The mitigative role of novel aflatoxin-degrading enzymes in diverse broiler performance indicators and gut microbiota following the consumption of diets contaminated with aflatoxins. JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2024; 104:7441-7453. [PMID: 38738519 DOI: 10.1002/jsfa.13564] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/14/2023] [Revised: 04/23/2024] [Accepted: 04/23/2024] [Indexed: 05/14/2024]
Abstract
BACKGROUND This study aims to explore both the toxic effects of aflatoxins (AFs) and the protective effects of degrading enzymes (DE) on broilers exposed to AFs. RESULTS The findings reveal that a diet contaminated with 69.15 μg kg-1 of aflatoxin B1 had significant adverse effects on broilers. Specifically, it led to a reduction in average daily gain, dressed yield percentage, half-eviscerated yield with giblet yield percentage, eviscerated yield percentage, as well as serum superoxide dismutase (SOD), glutathione peroxidase activity and liver SOD activity (P < 0.05). Conversely, the diet increased the feed conversion ratio, liver index, serum glutamic oxaloacetic transaminase levels and malondialdehyde levels in both serum and liver (P < 0.05). Additionally, AFs disrupted the intestinal microflora significantly (P < 0.05), altering the relative abundance of Enterococcus, Lactobacillus and Escherichia in broiler jejunum. The addition of DE to AF-contaminated feed mitigated these negative effects and reduced the residues of aflatoxin B1, aflatoxin B2 and aflatoxin M1 in the liver and duodenum (P < 0.05). We also observed that broilers fed the diet pelleted at 80 °C exhibited improved dressing percentage and water holding capacity compared to those on the 75 °C diet. CONCLUSION In summary, DE serves as an effective feed additive for mitigating AF contamination in poultry production. © 2024 Society of Chemical Industry.

The protective effects of Lactobacillus SNK-6 on growth, organ health, and intestinal function in geese exposed to low concentration Aflatoxin B1. Poult Sci 2024; 103:103904. [PMID: 38880050 PMCID: PMC11228886 DOI: 10.1016/j.psj.2024.103904] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2024] [Revised: 05/22/2024] [Accepted: 05/22/2024] [Indexed: 06/18/2024] Open
Abstract
Aflatoxin B1 (AFB1) is a prevalent mycotoxin present in feed ingredients. In this study, we investigated the effects of Lactobacillus salivarius (L. salivarius) on the Landes geese exposed to AFB1. The 300 one-day-old Landes geese were randomly divided into five groups: The control group received a basic diet, while the other groups were fed a basic diet supplemented with 10 μg/kg AFB1, 10 μg/kg AFB1+ 4*108 cfu/g L. salivarius, 50 μg/kg AFB1, and 50 μg/kg AFB1 + 4*108 cfu/g L. salivarius for 63 d. Results showed that high level AFB1 exposure significantly decreased final BW and ADG, increased feed/gain ratio (F/G) and liver index (P < 0.05). L. salivarius improved levels of IL-1, IL-6, and IL-12 under low level of AFB1 exposure (P < 0.05), along with similar trends observed in serum IgA, IgG, IgM, T3, T4, TNF-ɑ, and EDT (P < 0.05). AFB1 exposure reduced jejunum villus high and villus high/crypt depth ratio, and suppressed expression of ZO-1, Occludin, and Claudin-1 mRNA, and significant improved with L. salivarius supplementation under low level AFB1 exposure (P < 0.05). AFB1 significantly increased expression levels of TLR3 and NF-kB1, with supplementation of L. salivarius showing significant improvement under low AFB1 exposure (P < 0.05). Cecal microbiota sequencing revealed that under low level AFB1 exposure, supplementation with L. salivarius increased the abundance of Bacteroidetes and Lactococcus. In summary, supplementation with 4*108 cfu/g L. salivarius under 10 μg/kg AFB1 exposure improved growth performance and immune capacity, enhanced jejunum morphology, reduced liver inflammation, altered the cecal microbial structure, and positively affected the growth and development of geese.

Protective effects of feed additives on broiler chickens exposed to aflatoxins-contaminated feed: a systematic review and meta-analysis. Vet Res Commun 2024; 48:225-244. [PMID: 37644237 DOI: 10.1007/s11259-023-10199-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2023] [Accepted: 08/11/2023] [Indexed: 08/31/2023]
Abstract
Aflatoxin contamination in feed is a common problem in broiler chickens. The present systematic review and meta-analysis examined the impact of aflatoxin-contaminated feed and the efficacy of various feed additives on the production performance of broiler chickens fed aflatoxin-contaminated feed (AF-feed). A total of 35 studies comprising 53 AF-feed experiments were selected following PRISMA guidelines. Feed additives included in the analyses were toxins binder (TB), mannan-oligosaccharides (MOS), organic acid (OA), probiotics (PRO), protein supplementation (PROT), phytobiotics (PHY), and additive mixture (MIX). Random effects model and a frequentist network meta-analysis (NMA) were performed to rank the efficacy of feed additives, reported as standardized means difference (SMD) at 95% confidence intervals (95% CI). Overall, broiler chickens fed AF-feed had significantly lower final body weight (BW) (SMD = 198; 95% CI = 198 to 238) and higher feed conversion ratio (SMD = 0.17; 95% CI = 0.13 to 0.21) than control. Treatments with TB, MOS, and PHY improved the BW of birds fed AF-feed (P < 0.05) to be comparable with non-contaminated feed or control. Predictions on final BW from the broiler-fed aflatoxin-contaminated diet were 15% lower than the control diet. Including feed additives in the aflatoxins diet could ameliorate the depressive effect. Remarkably, our network meta-analysis highlighted that TB was the highest-performing additive (P-score = 0.797) to remedy aflatoxicosis. Altogether, several additives, especially TB, are promising to ameliorate aflatoxicosis in broiler chickens, although the efficacy was low regarding the severity of the aflatoxicosis.

Abstract
In this study, three aflatoxin degrading enzyme genes, tv-adtz, arm-adtz and cu-adtz, were heterologously expressed in Pichia pastoris. The protein expression of the enzyme solution was detected by sodium dodecyl sulfate polyacrylamide gel electrophoresis, and the results showed that specific protein bands were detected and the target genes were successfully integrated into Pichia pastoris. The enzyme activities and detoxification efficiency of TV-ADTZ, Arm-ADTZ and Cu-ADTZ crude enzyme solutions were detected, and the highest enzyme activities were up to 3.57, 4.30, and 2.41 U mL-1 , and the highest degradation rates were up to 45.58%, 60.0% and 34.21%, respectively. Arm-ADTZ with the best degradation effect was selected and designed for detoxification application experiments to test its detoxification efficiency of AFB1 in aqueous phase and in the process of moldy ground corn and preparation of DDGS, respectively, and the degradation rates reached 78.94%, 56.48%, and 24.31% after 24 h of reaction, respectively. Thus, it can be seen that the aflatoxin-degrading enzyme gene was successfully integrated into Pichia pastoris and secreted for expression, and the expressed product could effectively degrade AFB1 .

Abstract
The diverse bacterial populations within the symbiotic microbiota play a pivotal role in both health and disease. Microbiota modulates critical aspects of tumor biology including cell proliferation, invasion, and metastasis. This regulation occurs through mechanisms like enhancing genomic damage, hindering gene repair, activating aberrant cell signaling pathways, influencing tumor cell metabolism, promoting revascularization, and remodeling the tumor immune microenvironment. These microbiota-mediated effects significantly impact overall survival and the recurrence of tumors after surgery by affecting the efficacy of chemoradiotherapy. Moreover, leveraging the microbiota for the development of biovectors, probiotics, prebiotics, and synbiotics, in addition to utilizing antibiotics, dietary adjustments, defensins, oncolytic virotherapy, and fecal microbiota transplantation, offers promising alternatives for cancer treatment. Nonetheless, due to the extensive and diverse nature of the microbiota, along with tumor heterogeneity, the molecular mechanisms underlying the role of microbiota in cancer remain a subject of intense debate. In this context, we refocus on various cancers, delving into the molecular signaling pathways associated with the microbiota and its derivatives, the reshaping of the tumor microenvironmental matrix, and the impact on tolerance to tumor treatments such as chemotherapy and radiotherapy. This exploration aims to shed light on novel perspectives and potential applications in the field.

Abstract
Mycotoxins are toxic compounds that pose a serious threat to animal health and food safety. Therefore, there is an urgent need for safe and efficient methods of detoxifying mycotoxins. As biotechnology has continued to develop, methods involving biological enzymes have shown great promise. Biological enzymatic methods, which can fundamentally destroy the structures of mycotoxins and produce degradation products whose toxicity is greatly reduced, are generally more specific, efficient, and environmentally friendly. Mycotoxin-degrading enzymes can thus facilitate the safe and effective detoxification of mycotoxins which gives them a huge advantage over other methods. This article summarizes the newly discovered degrading enzymes that can degrade four common mycotoxins (aflatoxins, zearalenone, deoxynivalenol, and ochratoxin A) in the past five years, and reveals the degradation mechanism of degrading enzymes on four mycotoxins, as well as their positive effects on animal production. This review will provide a theoretical basis for the safe treatment of mycotoxins by using biological enzyme technology.

Abstract
Mycotoxins, which are fungal metabolites, pose a significant global food safety concern by extensively contaminating food and feed, thereby seriously threatening public health and economic development. Many foodborne mycotoxins exhibit potent intestinal toxicity. However, the mechanisms underlying mycotoxin-induced intestinal toxicity are diverse and complex, and effective prevention or treatment methods for this condition have not yet been established in clinical and animal husbandry practices. In recent years, there has been increasing attention to the role of gut microbiota in the occurrence and development of intestinal diseases. Hence, this review aims to provide a comprehensive summary of the intestinal toxicity mechanisms of six common foodborne mycotoxins. It also explores novel toxicity mechanisms through the "key gut microbiota-key metabolites-key targets" axis, utilizing multiomics and precision toxicology studies with a specific focus on gut microbiota. Additionally, we examine the potential beneficial effects of probiotic supplementation on mycotoxin-induced toxicity based on initial gut microbiota-mediated mycotoxicity. This review offers a systematic description of how mycotoxins impact gut microbiota, metabolites, and genes or proteins, providing valuable insights for subsequent toxicity studies of mycotoxins. Furthermore, it lays a theoretical foundation for preventing and treating intestinal toxicity caused by mycotoxins and advancing food safety practices.

Abstract
Deoxynivalenol (DON) is the most frequently present mycotoxin contaminant in food and feed, causing a variety of toxic effects in humans and animals. Currently, a series of mechanisms involved in DON toxicity have been identified. In addition to the activation of oxidative stress and the MAPK signaling pathway, DON can activate hypoxia-inducible factor-1α, which further regulates reactive oxygen species production and cancer cell apoptosis. Noncoding RNA and signaling pathways including Wnt/β-catenin, FOXO, and TLR4/NF-κB also participate in DON toxicity. The intestinal microbiota and the brain-gut axis play a crucial role in DON-induced growth inhibition. In view of the synergistic toxic effect of DON and other mycotoxins, strategies to detect DON and control it biologically and the development of enzymes for the biodegradation of various mycotoxins and their introduction in the market are the current and future research hotspots.

Abstract
The presence of mycotoxins in cereals can pose a significant health risk to animals and humans. China is one of the countries that is facing cereal contamination by mycotoxins. Treating mycotoxin-contaminated cereals with established physical and chemical methods can lead to negative effects, such as the loss of nutrients, chemical residues, and high energy consumption. Therefore, microbial detoxification techniques are being considered for reducing and treating mycotoxins in cereals. This paper reviews the contamination of aflatoxins, zearalenone, deoxynivalenol, fumonisins, and ochratoxin A in major cereals (rice, wheat, and maize). Our discussion is based on 8700 samples from 30 provincial areas in China between 2005 and 2021. Previous research suggests that the temperature and humidity in the highly contaminated Chinese cereal-growing regions match the growth conditions of potential antagonists. Therefore, this review takes biological detoxification as the starting point and summarizes the methods of microbial detoxification, microbial active substance detoxification, and other microbial inhibition methods for treating contaminated cereals. Furthermore, their respective mechanisms are systematically analyzed, and a series of strategies for combining the above methods with the treatment of contaminated cereals in China are proposed. It is hoped that this review will provide a reference for subsequent solutions to cereal contamination problems and for the development of safer and more efficient methods of biological detoxification.

Abstract
INTRODUCTION Aflatoxin B1 (AFB1) is a carcinogen produced by Aspergillus flavus and Aspergillus parasiticus which grow on maize. Given the high prevalence of child stunting (ie, impaired growth) and other nutritional disorders in low-income and middle-income countries, where maize is consumed, the role of aflatoxin exposure may be significant. Observational reports have demonstrated associations between aflatoxin exposure and impaired child growth; however, most have been cross-sectional and have not assessed seasonal variations in aflatoxin, food preparation and dynamic changes in growth. Biological mechanistic data on how aflatoxin may exert an impact on child growth is missing. This study incorporates a prospective cohort of children from rural Guatemala to assess (1) temporal associations between aflatoxin exposure and child growth and (2) possible mediation of the gut microbiome among aflatoxin exposure, inflammation and child growth. METHODS AND ANALYSIS We will prospectively evaluate aflatoxin exposure and height-for-age difference trajectories for 18 months in a cohort of 185 children aged 6-9 months at enrolment. We will assess aflatoxin exposure levels and biomarkers of gut and systemic inflammation. We will examine the faecal microbiome of each child and identify key species and metabolic pathways for differing AFB1 exposure levels and child growth trajectories. In parallel, we will use bioreactors, inoculated with faeces, to investigate the response of the gut microbiome to varying levels of AFB1 exposure. We will monitor key microbial metabolites and AFB1 biotransformation products to study nutrient metabolism and the impact of the gut microbiome on aflatoxin detoxification/metabolism. Finally, we will use path analysis to summarise the effect of aflatoxin exposure and the gut microbiome on child growth. ETHICS AND DISSEMINATION Ethics approval was obtained from Arizona State University Institutional Review Board (IRB; STUDY00016799) and Wuqu' Kawoq/Maya Health Alliance IRB (WK-2022-003). Findings will be disseminated in scientific presentations and peer-reviewed publications.

Effects of Lactic Acid Bacteria Reducing the Content of Harmful Fungi and Mycotoxins on the Quality of Mixed Fermented Feed. Toxins (Basel) 2023; 15:toxins15030226. [PMID: 36977117 PMCID: PMC10056090 DOI: 10.3390/toxins15030226] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Revised: 03/13/2023] [Accepted: 03/14/2023] [Indexed: 03/19/2023] Open
Abstract
The contamination of fermented feeds and foods with fungi and mycotoxins is a major food safety issue worldwide. Certain lactic acid bacteria (LAB), generally recognized as safe (GRAS) fermentation probiotics, are able to reduce microbial and mycotoxins contamination. In this study, Lactiplantibacillus (L.) plantarum Q1-2 and L. salivarius Q27-2 with antifungal properties were screened as inoculants for mixed fermenting feed, and the fermentation and nutritional qualities, microbial community, and mycotoxins of mixed fermented feed were analyzed at different fermentation periods (1, 3, 7, 15, and 30 days, respectively). The findings indicated that the utilization of Q1-2 and Q27-2 strains in fermenting feed led to a decrease in pH and an increase in lactic acid concentration and the proportion of Lactiplantibacillus, while effectively restraining the proliferation of undesirable microorganisms. In particular, Q1-2 reduced the relative abundance of fungi including Fusarium and Aspergillus. Compared to the control group, the Q1-2 and Q27-2 groups reduced aflatoxin B1 by 34.17% and 16.57%, and deoxynivalenol by up to 90.61% and 51.03%. In short, these two LAB inoculants could reduce the contents of aflatoxin B1 and deoxynivalenol to the limited content levels stipulated by the Chinese National Standard GB 13078-2017. These findings suggest that the LAB strains of Q1-2 and Q27-2 have potential applications in the feed industry for the mitigation of mycotoxin pollution, thereby enhancing the quality of animal feed.

Abstract
Detoxification approaches are evolving from physical to biological to eliminate the toxins altogether. The current study was conducted to compare the impact of 2 newly developed toxin deactivators, Magnotox-alphaA (MTA) and Magnotox-alphaB (MTB) with a commercially available toxin binder, Mycofix PlusMTV INSIDE (MF) in alleviating the pernicious effects of aflatoxin B1 (AFB1) in laying hens. The treatments were: 1) negative control (NC; without AFB1), 2) positive control (PC; contaminated with 500 ppb AFB1), 3) MF (PC + 2 kg MF/ton feed), 4) MTA (PC + 2 kg MTA/ton feed), and 5) MTB (PC + 2 kg MTB/ton feed). Detoxifying bacteria revealed a substantial reduction of different toxins in vitro, in which 98.8, 94.5, and 73.3% degradation rates were achieved, respectively, for zearalenone (ZEN), patulin, and AFB1 in the first 1 h of exposure. The PC group had a sharp decline in egg production (EP; 68.83%) while MTB showed the superior EP (95.74%) followed by NC (90.66%), MF (86.57%), and MTA (82.08%; P ≤ 0.05). Egg weight (EW) was also observed to be inferior in PC group (53.80 g; P ≤ 0.05). Egg mass (EM) was higher in MTB (57.55 g) and NC (54.33 g) groups while PC produced the lowest (39.64 g; P ≤ 0.05). MTB and NC groups also demonstrated the best FCR, 1.62 and 1.68, respectively, and PC manifested the poorest FCR (1.98) with higher ADFI (P ≤ 0.05). MTB also produced a superior moisture content (MC; 82.11%) with inferior DM (17.89%) in ileum content (P ≤ 0.05). The greatest liver fat content was found in MF group (48.19%) and MTA yielded the superior serum β-carotene and Vit A. MDA level in yolk samples was influenced by treatments, rendering the highest level in PC group (P ≤ 0.05). Ileum microbiota and blood characteristics were also affected by treatments. In general, MTB proves to be a toxin-deactivator candidate with comparable results to that of commercially available toxin-binders.

Compound mycotoxin detoxifier alleviating aflatoxin B 1 toxic effects on broiler growth performance, organ damage and gut microbiota. Poult Sci 2022; 102:102434. [PMID: 36586389 PMCID: PMC9811249 DOI: 10.1016/j.psj.2022.102434] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Revised: 12/12/2022] [Accepted: 12/13/2022] [Indexed: 12/24/2022] Open
Abstract
The aim of this study was to evaluate the effects of compound mycotoxin detoxifier (CMD) on alleviating the toxic effect of aflatoxin B1 (AFB1) for broiler growth performance. One-kilogram CMD consists of 667 g aflatoxin B1-degrading enzyme (ADE, 1,467 U/g), 200 g montmorillonite and 133 g compound probiotics (CP). The feeding experiment was divided into 2 stages (1-21 d and 22-42 d). In the early stage, a total of 300 one-day-old Ross broilers were randomly divided into 6 groups, 5 replications for each group, 10 broilers (half male and half female) in each replication. In the later feeding stage, about 240 twenty-two-day-old Ross broilers were randomly divided into 6 groups, 8 replications for each group, 5 broilers in each replication. Group A: basal diet; group B: basal diet with 40 μg/kg AFB1; group C: basal diet with 1 g/kg CMD; groups D, E, and F: basal diet with 40 μg/kg AFB1 plus 0.5, 1.0 and 1.5 g/kg CMD, respectively. The results indicated that AFB1 significantly decreased average daily gain (ADG), protein metabolic rate, organ index of thymus, bursa of Fabricius (BF), superoxide dismutase (SOD), glutathione peroxidase (GSH-PX) and catalase activities in serum, and increased AFB1 residues in serum and liver (P < 0.05). Hematoxylin-Eosin (HE) staining analysis of jejunum, liver and kidney showed that AFB1 caused the main pathological changes with different degrees of inflammatory cell infiltration. However, CMD additions could alleviate the negative effects of AFB1 on the above parameters. The gut microbiota analysis indicated that AFB1 could significantly increase the abundances of Staphylococcus-xylosu, Esherichia-coli-g-Escherichia-Shigella, and decrease Lactobacillus-aviarius abundance (P < 0.05), but which were adjusted to almost the same levels as the control group by CMD addition. The correlative analysis showed that Lactobacillus-aviarius abundance was positively correlated with ADG, SOD and BF (P < 0.05), whereas Staphylococcus-xylosus abundance was positively correlated with AFB1 residues in serum and liver (P < 0.05). In conclusion, CMD could keep gut microbiota stable, alleviate histological lesions, increase growth performance, and reduce mycotoxin toxicity. The optimal CMD addition should be 1 g/kg in AFB1-contaminated broilers diet.

Abstract
A total of 480 one-day-old AA broiler chicks were randomly allocated to one of four treatments in a 2 × 2 factorial to investigate the effects of tannic acid (TA) on growth performance, relative organ weight, antioxidant capacity, and intestinal health in broilers dietary exposed to aflatoxin B1 (AFB1). Treatments were as follows: (1) CON, control diet; (2) TA, CON + 250 mg/kg TA; (3) AFB1, CON + 500 μg/kg AFB1; and (4) TA+AFB1, CON + 250 mg/kg TA + 500 μg/kg AFB1. There were 10 replicate pens with 12 broilers per replicate. Dietary AFB1 challenge increased the feed conversion ratio during days 1 to 21 (P < 0.05). The TA in the diet did not show significant effects on the growth performance of broilers during the whole experiment period (P > 0.05). The liver and kidney relative weight was increased in the AF challenge groups compared with the CON (P < 0.05). The addition of TA could alleviate the relative weight increase of liver and kidney caused by AFB1 (P < 0.05). Broilers fed the AFB1 diets had lower activity of glutathione peroxidase, catalase, total superoxide dismutase, S-transferase, and total antioxidant capacity in plasma, liver and jejunum, and greater malondialdehyde content (P < 0.05). Dietary supplemented with 250 mg/kg TA increased the activities of antioxidative enzymes, and decreased malondialdehyde content (P < 0.05). In addition, AFB1 significantly reduced the villus height and crypt depth ratio in the ileum on day 42 (P < 0.05). In conclusion, supplementation with 250 mg/kg TA could partially protect the antioxidant capacity and prevent the enlargement of liver in broilers dietary challenged with 500 μg/kg AFB1.

Abstract
Mycotoxins in feedstuffs are considered as a principal worry by food safety authorities worldwide because most of them can be transferred from the feed to food commodities of animal origin, and further consumed by humans. Therefore, effective alternatives for the reduction of the impact of mycotoxins need to be applied in the feed production industry. Applications of beneficial microorganisms (probiotics) can be alternative and applied as feed additives in order to reduce or eliminate the toxic effects of mycotoxins on animals. The aim of this article is to provide information on the role of beneficial microorganisms (probiotics) and point out their role in the reduction of the effect of mycotoxin toxicity in farming animals (mammals and poultry). The objective was to provide a summary of the existing knowledge based on the application of different strains belonging to the group of lactic acid bacteria (LAB) or yeasts that are already or can be future employed in the feed industry, in order to reduce mycotoxicosis presence in mammals and poultry exposed to mycotoxin-contaminated feed. Moreover, an overview of mycotoxins toxicity in mammals and poultry will be presented, and furthermore, the role of the beneficial microorganisms (including probiotics) in the reduction of mycotoxins toxicity (aflatoxicosis, deoxynivalenol, zearalenone, ochratoxin A, and fumonisin toxicities) will be described in detail.

Effects of Compound Mycotoxin Detoxifier on Alleviating Aflatoxin B 1-Induced Inflammatory Responses in Intestine, Liver and Kidney of Broilers. Toxins (Basel) 2022; 14:toxins14100665. [PMID: 36287934 PMCID: PMC9609892 DOI: 10.3390/toxins14100665] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 09/19/2022] [Accepted: 09/20/2022] [Indexed: 11/17/2022] Open
Abstract
In order to alleviate the toxic effects of aflatoxins B1 (AFB1) on inflammatory responses in the intestine, liver, and kidney of broilers, the aflatoxin B1-degrading enzyme, montmorillonite, and compound probiotics were selected and combined to make a triple-action compound mycotoxin detoxifier (CMD). The feeding experiment was divided into two stages. In the early feeding stage (1−21 day), a total of 200 one-day-old Ross broilers were randomly divided into four groups; in the later feeding stage (22−42 day), 160 broilers aged at 22 days were assigned to four groups: Group A: basal diet (4.31 μg/kg AFB1); Group B: basal diet with 40 μg/kg AFB1; Group C: Group A plus 1.5 g/kg CMD; Group D: Group B plus 1.5 g/kg CMD. After the feeding experiment, the intestine, liver, and kidney tissues of the broilers were selected to investigate the molecular mechanism for CMD to alleviate the tissue damages. Analyses of mRNA abundances and western blotting (WB) of inflammatory factors, as well as immunohistochemical (IHC) staining of intestine, liver, and kidney tissues showed that AFB1 aggravated the inflammatory responses through NF-κB and TN-α signaling pathways via TLR pattern receptors, while the addition of CMD significantly inhibited the inflammatory responses. Phylogenetic investigation showed that AFB1 significantly increased interleukin-1 receptor-associated kinase (IRAK-1) and mitogen-activated protein kinase (MAPK) activities (p < 0.05), which were restored to normal levels by CMD addition, indicating that CMD could alleviate cell inflammatory damages induced by AFB1.

Abstract
Bacillus subtilis can secret a variety of substances to improve human and animal gut health via inhibiting the proliferation of pathogenic bacteria. In this study, a fast-growing and stress-resistant strain of Bacillus subtilis M6 (B. subtilis M6) were isolated, which showed a strong antibacterial activity to E. coli K88, S. typhimurium ATCC14028, and S. aureus ATCC25923 in vitro. In vivo studies showed that B. subtilis M6 can significantly improve the average daily gain (ADG) using an AA broiler model. Dietary B. subtilis M6 improved the intestinal morphology. The villus height of jejunum and ileum were significantly increased. The concentration of malondialdehyde (MDA) in the ileal mucosa was significantly reduced in B. subtilis M6 treatment group, which suggested the oxidative stress of the ileum was significantly relieved. Though the β diversity of treatments was not significantly, B. subtilis M6 improved the composition of intestinal microbes, especially at the level of caecum genus, the dominant genus was changed from Ruminococcus to Akkermansia, which indicated the change of intestinal carbohydrate nutrition. In conclusion, these data indicate that the B. subtilis M6 shows a probiotic potential to improve intestinal health via altering gut microbiota.

Abstract
Dietary Lactobacillus acidophilus ATCC 4356 was used to relieve the impacts of aflatoxin B1 toxicity on the performances of Liza ramada. The control diet was without any additives, while the second and third diets were supplemented with aflatoxin B1 at 0.5 and 1 mg/kg. The fourth diet was supplemented with Lb. acidophilus ATCC 4356 at 1 × 106 CFU/mL per kg diet, while the fifth with aflatoxin B1 at 1 mg/kg and Lb. acidophilus ATCC 4356 at 1 × 106 CFU/mL per kg diet. The growth performance markedly increased (p < 0.05) in L. ramada fed Lb. acidophilus ATCC 4356, while aflatoxin B1 at 0.5 and 1 mg/kg groups showed a severe reduction. The red blood cells, hemoglobulin, hematocrit, and white blood cells were markedly increased in L. ramada fed Lb. acidophilus ATCC 4356 while decreased (p < 0.05) in fish fed aflatoxin B1 at 0.5 and 1 mg/kg. The blood total protein and albumin were markedly increased (p < 0.05) in L. ramada fed Lb. acidophilus ATCC 4356 while reduced in aflatoxin B1 at 0.5 and 1 mg/kg groups. The levels of total cholesterol and triglycerides were meaningfully increased in fish of the Lb. acidophilus ATCC 4356 and aflatoxin B1 at 1 mg/kg groups while decreased in aflatoxin B1 at 0.5 and 1 mg/kg groups. Alanine aminotransferase, aspartate aminotransferase, creatinine, and urea levels were markedly decreased (p < 0.05) in fish-fed Lb. acidophilus ATCC 4356 while increased in aflatoxin B1 at 0.5 and 1 mg/kg groups. The highest levels of blood glucose and cortisol were seen in fish contaminated with aflatoxin B1 at 1 mg/kg, while the lowest levels were observed in the fish fed Lb. acidophilus ATCC 4356 group (p < 0.05). The catalase and superoxide dismutase were markedly enhanced in the Lb. acidophilus ATCC 4356 group and severely declined in aflatoxin B1 at 0.5 and 1 mg/kg groups (p < 0.05). The malondialdehyde level was markedly reduced in fish fed Lb. acidophilus ATCC 4356 with or without aflatoxin B1 at 1 mg/kg diets while increased in fish contaminated with aflatoxin B1 at 0.5 and 1 mg/kg (p < 0.05). The control group had lower malondialdehyde levels than the aflatoxin B1 at 1 mg/kg group and higher than the Lb. acidophilus ATCC 4356 with or without aflatoxin B1 toxicity (p < 0.05). Histopathological examination revealed impaired intestines and livers in fish contaminated with aflatoxin B1 while Lb. acidophilus ATCC 4356 relieves the inflammation and protected the intestines and livers. In conclusion, dietary Lb. acidophilus ATCC 4356 is recommended to relieve the impacts of aflatoxicosis-induced hepatorenal failure and oxidative stress in L. ramada.

Abstract
The present study aims to evaluate the effects of lycopene (LYC) supplementation on the intestinal immune function, barrier function, and antioxidant capacity of broilers fed with aflatoxinB1 (AFB1) contaminated diet. A total of 144 one-day-old male Arbor Acres broilers were randomly divided into three dietary treatment groups; each group consisted of six replicates (eight birds in each cage). Treatments were: (1) a basal diet containing neither AFB1 nor LYC (Control), (2) basal diet containing 100 µg/kg AFB1, and (3) basal diets with 100 µg/kg AFB1 and 200 mg/kg LYC (AFB1 and LYC). The results showed that dietary LYC supplementation ameliorated the AFB1 induced broiler intestinal changes by decreasing the inflammatory cytokines interferon-γ (IFN-γ), interleukin 1beta (IL-1β), and increasing mRNA abundances of cludin-1 (CLDN-1) and zonula occludens-1 (ZO-1) in the jejunum mucosa. On the other hand, AFB1-induced increases in serum diamine oxidase (DAO) activities, D-lactate concentration, mucosal malondialdehyde (MDA), and hydrogen peroxide (H2O2) concentrations were reversed by dietary LYC supplementation (p < 0.05). Additionally, LYC supplementation ameliorated the redox balance through increasing the antioxidant enzyme activities and their related mRNA expression abundances compared to AFB1 exposed broilers. In conclusion, dietary supplementation with LYC could alleviate AFB1 induced broiler intestinal immune function and barrier function damage and improve antioxidants status.

Abstract
The aim of this study was to examine the impact of intake of a lactic acid bacterium, Lactobacillus plantarum 299v (Lp299v) on aflatoxin-induced hepatotoxicity in broilers. For this, broilers were intoxicated with dietary aflatoxins and simultaneously treated with live Lp299v in drinking water. One-day-old male broilers were divided into eight groups (n = 10/group) as follows. Aflatoxin groups fed basal diet contaminated with aflatoxins (200 or 2000 ppb). The probiotic groups received drinking water enriched with live (Lp299v) (108 CFU/ml). A group of birds was given a commercial mycotoxin binder (2.5 g/kg feed). Control groups received basal diet without probiotic or aflatoxin binder. The growth performance was calculated for the entire period (0-42 days), and blood and liver specimens were processed for histology and determination of liver damage markers. Results showed extensive damage including bile duct hyperplasia, hepatocellular ballooning, and necrosis in chickens fed aflatoxin alone. However, liver lesions were limited to lobular inflammation and pyknosis in broilers treated with aflatoxins along with Lp299v. The histology of the liver tissues from the birds on aflatoxin-free diet + probiotic appeared to be normal when compared to the respective controls. Histopathological indices in different experimental groups were corroborated with the liver damage markers namely, serum ALT, AST, LD, and γ-GT. It is concluded that the improvement in the growth performance and prevention of aflatoxin-related liver lesions could be mainly assigned to the probiotic therapy for the entire period of breeding, although the aflatoxin-binding ability of the Lp299v in inactivation of aflatoxins cannot be ruled out.RESEARCH HIGHLIGHTS Aflatoxin-related liver damage progression was inhibited by probiotics in broilers.Aflatoxin inactivation by probiotics can be assessed by liver histopathology.Growth performance in broilers was improved following the intake of probiotics.

Abstract
Food contamination such as toxins and heavy metals has been increasing in the last few decades as a result of industrialization in general and as part of food production in particular. Application of microorganisms in toxins and heavy metals bio-removal has been documented and applied as a favorable decontamination approach due to being environmentally friendly, reasonably simple, and economically feasible. Lactobacilli have been proposed and applied as a beneficial biologic sorbent for toxins and heavy metals in processes of reducing their hazardous bio-availability. The purpose of this review is to summarize the known role of Lactobacillus bacterial species in food bio-decontamination processes. After a quick glimpse of the worthy properties of lactobacilli, their cell wall structure is mentioned. Then the potential role of Lactobacillus strains for mycotoxins (aflatoxins, patulin, ochratoxin A, fumonisins, zearalenone, cyanotoxins, and trichothecenes) and heavy metals (lead, arsenic copper, mercury, cadmium, zinc, aluminum, chromium, and iron) bio-removal were described. In addition, the role of various factors in removal yield and the decontamination mechanism were explained. Finally, the lactobacilli-contaminant stability, in vivo studies, and being a friend or foe of Lactobacillus bacteria are discussed.

Abstract
Aflatoxin B1 (AFB1) contamination in feed and food seriously threatens the healthy growth of animals and humans, and it may lead to huge economic losses in livestock and poultry production. Therefore, screening of high-efficient AFB1-degrading bacteria is necessary to ensure the safety of feed and food. The study aims to isolate and characterize bacteria from various sources to explore its AFB1 degradation potential. Fifteen bacterial were obtained using a medium containing coumarin as the sole carbon source; only one strain showed a good-degrading ability in culture media by adding AFB1 and it was selected for further studies. A gram-negative and spore-forming, designated E1, was identified as Paenibacillus pabuli, with the highest sequence similarity to P. pabuli NBRC13638T (98.97%). The growth of the strain E1 was observed under 22-47 °C, pH 5.5-9.5 and NaCl concentration 0-6% (w/v), with optimum growth at 37 °C, pH 7.5 and 1% NaCl. The biodegradation characteristics of object strain were detected by high performance liquid chromatography (HPLC). The degradation ratio of AFB1 reached 55% at 24 h and 70.2% at 48 h. After 96 h, the degradation rate of AFB1 reached 85.9%. The active degradation components were present in the cell-free supernatant of strain E1, and the degradation ratio of AFB1 reached 80.0% after 96 h. It is the first report that genus Paenibacillus could degrade AFB1. Moreover, E1 has highly adaptable to diverse environmental conditions. It will be a potential candidate for biodegradation of mycotoxins in feed and food.

Abstract
The aim of this study was to evaluate the detoxification of aflatoxin B1 (AFB1) in vitro and in broiler chickens using a triple-action compound mycotoxin detoxifier (CMD). Response surface methodology (RSM) was used to evaluate AFB1 detoxification in artificial gastrointestinal fluid (AGIF) in vitro. The AFB1-degradation rate was 41.5% (P < .05) when using a compound probiotic (CP) in which the visible counts of Bacillus subtilis, Lactobacillus casein, Enterococcus faecalis and Candida utilis were 1.0 × 105, 1.0 × 105, 1.0 × 107 and 1.0 × 105 CFU/mL, respectively. When CP was combined with 0.1% AFB1-degrading enzyme to give CPADE, the AFB1-degradation rate was increased to 55.28% (P < .05). The AFB1-removal rate was further increased to above 90% when CPADE was combined with 0.03% montmorillonite to make CMD. In vivo, a total of 150 one-day-old Ross broilers were allotted to 3 groups, 5 replications for each group, 10 broilers in each replication. Group A: basal diet, Group B: basal diet with 40 μg/kg AFB1, Group C: basal diet with 40 μg/kg AFB1 plus CMD. The feeding experiment period was 21 d. The results showed that broiler growth was increased, and AFB1 residues in serum, excreta and liver were decreased by CMD addition in broiler diet (P < .05). In conclusion, CMD was able to remove AFB1 efficiently in vitro and to increase broiler production performance and reduce AFB1 residues in the chickens.

Abstract
Aflatoxins (AFs) are a class of mycotoxins produced by the toxigenic Aspergillus fungi and are common contaminants of foods and feeds. Aflatoxin B1 (AFB1), the most potent aflatoxin, is well characterized to reduce productive performance and mortality in broilers. This exclusive review summarizes the efficacy of various plant products and phytochemicals to counteract AFB1 toxicity in broilers. The biochemical and molecular mode of action of AFB1 to induce liver damage, genotoxicity, immunosuppression and the protective effect of plant products against such mechanisms and their toxic effects are discussed. The link between antioxidant, immunomodulatory and hepatoprotective functions of plant products; oxidative stress and AFB1 macromolecular adducts mediated AFB1 toxicity are covered. Efficacy of Satureja khuzistanica, Zataria multiflora Boiss, Thymus vulgaris, Sauropsus androgynus, Hemidesmus indicus, Leucas aspera, Moringa oleifera, Eclipta alba, Curcuma longa, Silybum marianum, Urtica dioica, and citrus fruit are summarized. The anti-aflatoxic effect of water-soluble substances of wheat, grape seed proanthocyanidin extract and phytochemicals like thymol, carvarol, piperine, transcinnamaldehyde, resveratrol, curcumin, and silymarin are also discussed. Specific plant products and phytochemicals are shown to be effective against AF toxicity in broilers and could represent an important tool to reduce health and economic losses associated with AFB1 exposure.

Abstract
Aflatoxin B1 (AFB1) is one of the most dangerous mycotoxins for humans and animals. This study aimed to investigate the effects of compound probiotics (CP), CP supernatant (CPS), AFB1-degradation enzyme (ADE) on chicken embryo primary intestinal epithelium, liver and kidney cell viabilities, and to determine the functions of CP + ADE (CPADE) or CPS + ADE (CPSADE) for alleviating cytotoxicity induced by AFB1. The results showed that AFB1 decreased cell viabilities in dose-dependent and time-dependent manners. The optimal AFB1 concentrations and reactive time for establishing cell damage models were 200 µg/L AFB1 and 12 h for intestinal epithelium cells, 40 µg/L and 12 h for liver and kidney cells. Cell viabilities reached 231.58% (p < 0.05) for intestinal epithelium cells with CP addition, 105.29% and 115.84% (p < 0.05) for kidney and liver cells with CPS additions. The further results showed that intestinal epithelium, liver and kidney cell viabilities were significantly decreased to 87.12%, 88.7% and 84.19% (p < 0.05) when the cells were exposed to AFB1; however, they were increased to 93.49% by CPADE addition, 102.33% and 94.71% by CPSADE additions (p < 0.05). The relative mRNA abundances of IL-6, IL-8, TNF-α, iNOS, NF-κB, NOD1 (except liver cell) and TLR2 in three kinds of primary cells were significantly down-regulated by CPADE or CPSADE addition, compared with single AFB1 group (p < 0.05), indicating that CPADE or CPSADE addition could alleviate cell cytotoxicity and inflammation induced by AFB1 exposure through suppressing the activations of NF-κB, iNOS, NOD1 and TLR2 pathways.

Abstract
Nutraceuticals have taken on considerable significance due to their supposed safety and possible nutritional and medicinal effects. Pharmaceutical and dietary companies are conscious of monetary success, which benefits healthier consumers and the altering trends that result in these heart-oriented value-added products being proliferated. Numerous nutraceuticals are claimed to have multiple therapeutic benefits despite advantages, and unwanted effects encompass a lack of substantial evidence. Several common nutraceuticals involve glucosamine, omega-3, Echinacea, cod liver oil, folic acid, ginseng, orange juice supplemented with calcium, and green tea. This review is dedicated to improving the understanding of nutrients based on specific illness indications. It was reported that functional foods contain physiologically active components that confer various health benefits. Studies have shown that some foods and dietary patterns play a major role in the primary prevention of many ailment conditions that lead to putative functional foods being identified. Research and studies are needed to support the possible health benefits of different functional foods that have not yet been clinically validated for the relationships between diet and health. The term "functional foods" may additionally involve health/functional health foods, foods enriched with vitamins/minerals, nutritional improvements, or even conventional medicines.

Abstract
Mycotoxin contamination causes significant economic loss to food and feed industries and seriously threatens human health. Aflatoxins (AFs) are one of the most harmful mycotoxins, which are produced by Aspergillus flavus, Aspergillus parasiticus, and other fungi that are commonly found in the production and preservation of grain and feed. AFs can cause harm to animal and human health due to their toxic (carcinogenic, teratogenic, and mutagenic) effects. How to remove AF has become a major problem: biological methods cause no contamination, have high specificity, and work at high temperature, affording environmental protection. In the present research, microorganisms with detoxification effects researched in recent years are reviewed, the detoxification mechanism of microbes on AFs, the safety of degrading enzymes and reaction products formed in the degradation process, and the application of microorganisms as detoxification strategies for AFs were investigated. One of the main aims of the work is to provide a reliable reference strategy for biological detoxification of AFs.

Abstract
Animal feeds may contain exogenous compounds that can induce toxicity when ruminants ingest them. These toxins are secondary metabolites originating from various sources including plants, bacteria, algae and fungi. Animal feed toxins are responsible for various animal poisonings which negatively impact the livestock industry. Poisoning is more frequently reported in newly exposed, naïve ruminants while ‘experienced’ ruminants are observed to better tolerate toxin-contaminated feed. Ruminants can possess detoxification ability through rumen microorganisms with the rumen microbiome able to adapt to utilise toxic secondary metabolites. The ability of rumen microorganisms to metabolise these toxins has been used as a basis for the development of preventative probiotics to confer resistance against the poisoning to naïve ruminants. In this review, detoxification of various toxins, which include plant toxins, cyanobacteria toxins and plant-associated fungal mycotoxins, by rumen microorganisms is discussed. The review will include clinical studies of the animal poisoning caused by these toxins, the toxin mechanism of action, toxin degradation by rumen microorganisms, reported and hypothesised detoxification mechanisms and identified toxin metabolites with their toxicity compared to their parent toxin. This review highlights the commercial potential of rumen inoculum derived probiotics as viable means of improving ruminant health and production.

Abstract
In order to alleviate toxic effects of aflatoxins B1 (AFB1) and zearalenone (ZEA) on broiler production performance and gut microbiota, three kinds of compound probiotics (CP) were selected. The optimal ratios of Bacillus subtilis, Lactobacillus casei and Candida utilis in broiler diets were 7, 5 and 6 log CFU/g for ZEA biodegradation (CP1); 6, 7 and 7 log CFU/g for AFB1 biodegradation (CP2); 7, 6 and 7 log CFU/g for ZEA + AFB1 biodegradation (CP3). A total of 350 1-day-old Ross broilers were randomly divided into 7 groups. Group A was the basal diet, group B-G contained ZEA, AFB1, ZEA + AFB1, ZEA + CP1, AFB1+CP2, ZEA + AFB1+CP3, respectively. The experiment showed that AFB1 or AFB1+ZEA significantly decreased broiler production performance, damaged liver and jejunum, increased mycotoxin residues in broiler body; however, three kinds of compound probiotics additions could alleviate mycotoxin negative effects on the above parameters (p < 0.05). The gut microbiota analysis indicated that AFB1+ZEA increased jejunal microbial richness, but which were decreased to almost the same level as the control group by CP3 addition. CP3 addition significantly increased jejunal Firmicutes and Lactobacillus aviarius abundances. The correlative analysis showed that gut Lactobacillus aviarius abundance was positively correlated with average daily gain (ADG) of broilers (p < 0.05), while AFB1+ZEA addition decreased its relative abundance, indicating that CP3 addition increased broiler growth by increasing Lactobacillus aviarius abundance. AFB1 and ZEA residues in broiler body were negatively correlated with the gut beneficial bacterial abundances (p < 0.01), but positively correlated with the potentially harmful bacterial abundances (p < 0.05), which inferred that CP3 addition could decrease mycotoxin residues through positively regulating gut relative bacterial abundances. In conclusion, compound probiotics could keep gut microbiota stable, degrade mycotoxins, alleviate histological lesions, increase production performance and reduce mycotoxin toxicity for broilers.

Abstract
The aim of this study was to investigate the impact of mycotoxin binders on the determination of aflatoxins in maize and maize gluten using various analytical methods, including ELISA, HPLC and LC-MS/MS. Three types of commercially available mycotoxin binders, yeast cell wall, mineral, and a mixture of mineral and bacterium, were investigated at inclusion levels of 0.1%, 0.2% and 0.4%. The binders were added to maize and maize gluten contaminated with aflatoxins at concentrations between 6.9 and 26.7 μg kg-1. The samples were analysed and the values were compared with corresponding controls (samples without binders) using ANOVA. The yeast cell wall binder had no significant effect (p=0.05) on the concentration of aflatoxins measured in either maize or maize gluten at any of the three inclusion levels, regardless of which analytical method was used. The mineral binder and the mixed mineral and bacterium binder had no significant effect (p=0.05) on the measured aflatoxin concentrations in either maize or maize gluten at any of the three inclusion levels when analysis was conducted using LC-MS/MS. Inclusion of these binders resulted in significant lower (p<0.01) detection of aflatoxins in both maize and maize gluten when analysis was conducted using ELISA; the effect was dose-dependent. They also resulted in significant lower detection of aflatoxins in maize extracted by methanol/water (70/30 v/v) (p<0.0001) and in maize gluten extracted by acetonitrile/water (80/20 v/v) (p<0.05) when analysis was conducted using HPLC. However, neither the mineral binder nor the mixed mineral and bacterium binder had significant effects (p=0.05) on aflatoxin concentrations measured in maize using HPLC, when extracted by acetonitrile/water (80/20 v/v). The study demonstrated that mycotoxin binders could result in underestimation of the levels of aflatoxin contamination, depending on the nature of the binder, the extraction solvent used in the analytical method, and the composition of tested sample.

Abstract
Abstract
Background
Aflatoxin B1 (AFB1) is classified as a Group I carcinogen. A Previous study found that oxidative stress from the metabolism of AFB1 induced hepatotoxic effects in wheat miller workers. Zinc and vitamin C may play a significant role in the activation of detoxification and overcoming the oxidative stress of AFB1.
Objectives
A prospective clinical trial was designed to evaluate the role of zinc and vitamin C oral supplementation on the oxidant-antioxidant status and the hepatotoxic effects of AFB1 in wheat miller workers.
Methods
Liver enzymes (ALT, AST, ALP, and GGT), P53 protein, malondialdehyde (MDA), glutathione S transferase (GST), Superoxide dismutase (SOD), zinc and vitamin C were estimated in 35 wheat miller workers before and after zinc and vitamin C supplementation for 1 month.
Results
The results revealed that zinc and vitamin C were significantly increased after the one-month supplementation, while liver enzymes (AST, ALP, and GGT), MDA, and GST of the workers were significantly decreased. SOD and P53 were also decreased but not to a significant level; SOD was decreased in 56% and P53 was decreased in 58% of the total workers.
Conclusions
Zinc and vitamin C oral supplementation for 1 month had an ameliorative effect on the hepatotoxicity of AFB1 in wheat miller workers, through decreasing MDA, SOD, and GST levels that in turn led to an improvement in their liver enzymes. Further study on a larger scale is needed to confirm these results.

Abstract
Pullorum disease is one of the most serious poultry diseases. Antibiotic prophylaxis is commonly applied in actual production, but the emergence of drug-resistant strains and drug residues threatens the health of animals and humans. The use of probiotics has become a potential solution for the aforementioned problem. In this study, we investigated the effects of Lactobacillus casei DBN023 (CGMCC-16146) on the intestinal tissue structure and immune functions of the jejunal epithelium in chicks infected with Salmonella pullorum CMCC-533 using histomorphological and immunological methods. A total of 450 newborn chicks were randomly divided into the control group and experimental groups. We used hematoxylin and eosin (H&E) staining, immunohistochemistry (IHC), and an enzyme-linked immunosorbent assay (ELISA) to observe the structure of the jejunal mucosa and analyze changes in cytokine and secretory immunoglobulin A (sIgA) levels. The results showed that prophylactic feeding of L. casei DBN023 to chicks significantly increased their jejunum villar height, villar height-to-crypt-depth (V/C) ratio, and muscle thickness; reduced intestinal-crypt depth; and increased the proliferating cell nuclear antigen (PCNA) level compared with S. pullorum infection. L. casei DBN023 enhances intestinal mucosal immunity, regulates cytokine balance, enhances intestinal immune function, and effectively reduces intestinal inflammation. Thus, it protects intestinal tissues and reduces S. pullorum CMCC-533 damage to the intestinal tract.

Zearalenone Biodegradation by the Combination of Probiotics with Cell-Free Extracts of Aspergillus oryzae and its Mycotoxin-Alleviating Effect on Pig Production Performance. Toxins (Basel) 2019; 11:toxins11100552.

Abstract
In order to remove zearalenone (ZEA) detriment—Bacillus subtilis, Candida utilis, and cell-free extracts from Aspergillus oryzae were used to degrade ZEA in this study. The orthogonal experiment in vitro showed that the ZEA degradation rate was 92.27% (p < 0.05) under the conditions that Candida utilis, Bacillus subtilis SP1, and Bacillus subtilis SP2 were mixed together at 0.5%, 1.0%, and 1.0%. When cell-free extracts from Aspergillus oryzae were combined with the above probiotics at a ratio of 2:1 to make mycotoxin-biodegradation preparation (MBP), the ZEA degradation rate reached 95.15% (p < 0.05). In order to further investigate the MBP effect on relieving the negative impact of ZEA for pig production performance, 120 young pigs were randomly divided into 5 groups, with 3 replicates in each group and 8 pigs for each replicate. Group A was given the basal diet with 86.19 μg/kg ZEA; group B contained 300 μg/kg ZEA without MBP addition; and groups C, D, and E contained 300 μg/kg ZEA added with 0.05%, 0.10%, and 0.15% MBP, respectively. The results showed that MBP addition was able to keep gut microbiota stable. ZEA concentrations in jejunal contents in groups A and D were 89.47% and 80.07% lower than that in group B (p < 0.05), indicating that MBP was effective in ZEA biodegradation. In addition, MBP had no significant effect on pig growth, nutrient digestibility, and the relative mRNA abundance of estrogen receptor alpha (ERα) genes in ovaries and the uterus (p > 0.05).

Abstract
Zearalenone (ZEA) is a mycotoxin produced by Fusarium fungi that is commonly found in cereal crops. ZEA has an estrogen-like effect which affects the reproductive function of animals. It also damages the liver and kidneys and reduces immune function which leads to cytotoxicity and immunotoxicity. At present, the detoxification of mycotoxins is mainly accomplished using biological methods. Microbial-based methods involve zearalenone conversion or adsorption, but not all transformation products are nontoxic. In this paper, the non-pathogenic microorganisms which have been found to detoxify ZEA in recent years are summarized. Then, two mechanisms by which ZEA can be detoxified (adsorption and biotransformation) are discussed in more detail. The compounds produced by the subsequent degradation of ZEA and the heterogeneous expression of ZEA-degrading enzymes are also analyzed. The development trends in the use of probiotics as a ZEA detoxification strategy are also evaluated. The overall purpose of this paper is to provide a reliable reference strategy for the biological detoxification of ZEA.

Abstract
Mycotoxins are highly dangerous natural compounds produced by various fungi. Enzymatic transformation seems to be the most promising method for detoxification of mycotoxins. This review summarizes current information on enzymes of different classes to convert various mycotoxins. An in-depth analysis of 11 key enzyme mechanisms towards dozens of major mycotoxins was realized. Additionally, molecular docking of mycotoxins to enzymes' active centers was carried out to clarify some of these catalytic mechanisms. Analyzing protein homologues from various organisms (plants, animals, fungi, and bacteria), the prevalence and availability of natural sources of active biocatalysts with a high practical potential is discussed. The importance of multifunctional enzyme combinations for detoxification of mycotoxins is posed.

Abstract
Zearalenone (ZEA) and aflatoxin B1 (AFB1) are two main kinds of mycotoxins widely existing in grain and animal feed that cause a lot of economic loss and health problems for animals and humans. In order to alleviate the cytotoxic effects of AFB1 and ZEA on swine jejunal epithelial cells (IPEC-J2), the combination of a cell-free supernatant of compound probiotics (CFSCP) with mycotoxin degradation enzymes (MDEs) from Aspergillus oryzae was tested. The results demonstrated that coexistence of AFB1 and ZEA had synergetic toxic effects on cell viability. The cell viability was decreased with mycotoxin concentrations increasing, but increased with incubation time extension. The necrotic cell rates were increased when 40 µg/L AFB1 and/or 500 µg/L ZEA were added, but the addition of CFSCP + MDE suppressed the necrotic effects of AFB1 + ZEA. The viable cell rates were decreased when AFB1 and/or ZEA were added: However, the addition of CFSCP + MDE recovered them. The relative mRNA abundances of Bcl-2, occludin, and ZO-1 genes were significantly upregulated, while Bax, caspase-3, GLUT2, ASCT2, PepT1, and IL6 genes were significantly downregulated by CFSCP + MDE addition, compared to the groups containing 40 µg/L AFB1 and 500 µg/L ZEA. This research provided an effective strategy in alleviating mycotoxin cytotoxicity and keeping normal intestinal cell structure and animal health.

Abstract
Growing broiler chicks on a diet contaminated with aflatoxins (200 or 2000 ppb) for entire growth period resulted in increased oxidative stress and liver damage markers. The toxicity was subsided in broilers received a specific aflatoxin-binding probiotic i.e., Lactobacillus plantarum 299v (Lp299v). There was a substantial (30-90%) increase in antioxidant activity of plasma, which was suppressed due to dietary aflatoxins. Probiotic also reduced serum lactate dehydrogenase and alanine amino transferase together with lipid peroxidation products in liver, which were elevated due to aflatoxin. Because of Lp299v consumption, there was ∼20-55% recovery in body weight gain in broilers intoxicated with aflatoxins. Comparison of the Lp299v effects with that of a commercial aflatoxin binder revealed that, improved antioxidant activity of the chicks was associated with growth performance. These data suggest that aflatoxin-binding probiotics are beneficial with multi-functional effects and can efficiently help reducing aflatoxins in food chain associated with poultry industry.

Abstract
Aflatoxin B1 (AFB1) and zearalenone (ZEA) are the secondary toxic metabolites of fungi which contaminate a wide range of food and feedstuffs. Limiting exposure of humans and livestock to them is very essential. Among numerous methods of mycotoxin-degradation, biodegradation by microorganisms and enzymes is an effective and promising approach to eliminate their hazards. The present study aims to optimize the proportion of different species of beneficial microbes by means of response surface methodology (RSM) and its combination with mycotoxin-degradation enzymes. The results indicated that AFB1 and ZEA degradation rates were 38.38% and 42.18% by individual Bacillus subtilis (P < 0.05); however, AFB1 and ZEA degradation rates reached 45.49% and 44.90% (P < 0.05) when three probiotic species such as Bacillus subtilis, Lactobacillus casein and Candida utilis were at a ratio of 1:1:1, corresponding with the predictive value of the RSM model. The further experiment showed that AFB1 and ZEA degradation rates were 63.95% and 73.51% (P < 0.05) when the compound of three probiotic species was combined with mycotoxin-degradation enzymes from Aspergillus oryzae at a ratio of 3:2. This result indicated that the combination of probiotics with mycotoxin-degradation enzymes is a promising new approach for synchronous detoxification of AFB1 and ZEA.

Abstract
The present study aimed to investigate the toxic effect of aflatoxin B1 (AFB1) and the effectiveness of a biological mycotoxin binder (Nutritox®) in detoxifying aflatoxicosis. Ninety one-day-old chicks were chosen and divided into 3 groups. The first group received standard basal diet only, the second group received a basal diet with AFB1 (0.25 mg/kg diet), and the third group received a basal diet with AFB1 (0.25 mg/kg diet) and Nutritox® (1 kg/ton diet). AFB1 feed contamination significantly reduced growth performance and deteriorated FCR. Moreover, it significantly increased serum AST, ALT, and malondialdehyde and significantly decreased serum total protein, albumin, globulin, SOD, CAT activities and glutathione peroxidase gene expression as well. Aflatoxin residues were detected in the liver tissues. Furthermore, the liver and kidney of AFB1 treated group showed pathological changes. The supplementation of Nutritox® significantly reduced aflatoxin levels in the liver and counteracted the negative effects of AFB1.

Abstract
Lactic acid bacteria (LAB) and the glutathione (GSH) pathway are protective against aflatoxin, but information on the effect of LAB on aflatoxin metabolism and GSH activity in farm animals is scarce. This study aimed to investigate the effects of LAB and aflatoxin B (AFB) on growth performance, aflatoxin metabolism, and GSH pathway activity using 480 male Arbor Acres broiler chickens from d 1 to 35 of age. Diets were arranged in a 2 × 2 factorial design, including AFB at 0 or 40 µg/kg of feed and LAB at 0 or 3 × 10 cfu/kg of feed, and the LAB was a mixture of equal amounts of , , and . The results showed that there were highly significant ( < 0.01) effects of AFB toxicity, LAB protection, and their interaction on ADFI, ADG, and G:F of broilers during d 1 to 35. Compared with the AFB diet, the LAB diet reduced ( < 0.05) the residues of AFB in the liver, kidney, serum, ileal digesta, and excreta on d 14 by 121.5, 80.6, 43.7, 47.0, and 26.5%, respectively, and on d 35 by 40.6, 60.2, 131.7, 37.9, and 32.9%, respectively, whereas the LAB diet increased ( < 0.05) the contents of aflatoxin M, a metabolite of AFB, in the liver, kidney, serum, and ileal digesta on d 14 by 98.2, 154.2, 168.6, 19.1, and 34.1%, respectively, and in the kidney and serum on d 35 by 32.6 and 142.2%, respectively. For the activity of the GSH pathway in the liver and duodenal mucosa, there were significant ( ≤ 0.01) effects of LAB and AFB on reduced GSH, glutathione S-transferases (GST), and glutathione reductase (GR) on d 14 and 35; compared with the control diet, the LAB diet increased ( < 0.05) GSH, GST, and GR by a range of 11.6 to 86.1%, and compared with the AFB diet, the LAB diet increased ( < 0.05) GSH, GST, and GR by a range of 24.1 to 146.9%. In the liver, there were interactions ( < 0.05) on GSH and GST on d 14 and on GSH on d 35; in the mucosa, interactions were significant ( ≤ 0.01) on GSH and GR on d 14 and on GST on d 35. It can be concluded that LAB is effective in the detoxification of AFB by modulating toxin metabolism and activating the GSH pathway in animals.

Effects of lactic acid bacteria and smectite after aflatoxin B 1 challenge on the growth performance, nutrient digestibility and blood parameters of broilers. J Anim Physiol Anim Nutr (Berl) 2018; 102:953-961. [PMID: 29638014 DOI: 10.1111/jpn.12901] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2017] [Accepted: 03/12/2018] [Indexed: 11/30/2022]
Abstract
This study aimed to investigate the effect of lactic acid bacteria (LAB) and smectite on the growth performance, nutrient digestibility and blood parameters of broilers that were fed diets contaminated with aflatoxin B1 (AFB1 ). A total of 480 newly hatched male Arbor Acres broilers were randomly allocated into four groups with six replicates of 20 chicks each. The broilers were fed diets with the AFB1 (40 μg/kg) challenge or without (control) it and supplemented with smectite (3.0 g/kg) or LAB (4.0 × 1010 CFU/kg) based on the AFB1 diet. The trial lasted for 42 days. The results showed that during days 1-42 of AFB1 challenge, the feed intake (FI) and body weight gain (BWG) were depressed (p < .05). The inclusion of LAB and smectite increased (p < .05) the BWG by 71.58 and 41.89 g/bird, respectively, which reached the level of the control diet (p ≥ .05), but there were no differences (p ≥ .05) in performance between LAB and smectite. LAB and smectite also increased (p < .05) the apparent total tract digestibility of the crude protein. Regarding the blood parameters, AFB1 decreased (p < .05) the levels of red blood cell count, haematocrit, mean corpuscular volume, haemoglobin, albumin and total protein. In the meantime, the AFB1 increased (p < .05) leucocyte counts, urea nitrogen, cholesterol, total bilirubin, creatinine, glutamic-pyruvic transaminase, glutamic oxaloacetic transaminase and alkaline phosphatase. By contrast, LAB and smectite affected (p < .05) these parameters in the opposite direction. It can be concluded that after the AFB1 challenge, LAB and smectite have similar effects on the growth and health of the broilers, suggesting that LAB could be an alternative against AFB1 in commercial animal feeds.

Abstract
Aflatoxin B1 (AFB1) causes hepatotoxic, genotoxic, and immunotoxic effects in a variety of species. Although various neutralizing agents of AFB1 toxicity have been studied, the egg yolk immunoglobulin (IgY) detoxification of small molecular toxins and the mechanisms underlying such effects have not yet been reported. In this investigation, anti-AFB1 IgY against AFB1 was successfully raised, and a competitive indirect enzyme-linked immunosorbent assay was established with a sensitive half-maximal inhibitory concentration (IC50, 2.4 ng/mL) and dynamic working range (0.13-43.0 ng/mL). The anti-AFB1 IgY obtained reduced AFB1-induced cytotoxicity, cellular dysfunction, and genotoxicity by protecting cells against apoptotic body formation and DNA strand breaks, preventing G2/M phase cell cycle arrest, reducing AFB1-DNA adduct and reactive oxygen species production and maintaining cell migration and invasion and the mitochondrial membrane potential. Anti-AFB1 IgY significantly inhibited the AFB1-induced expression of proteins related to antioxidative, pro-apoptotic, and antiapoptotic processes in a strong dose-dependent manner. These experiments demonstrated that the anti-AFB1 IgY-bound AFB1 could not enter cells. This is the first time that IgY has been found to reduce the effects of small molecular toxins, which will be beneficial for the development of antibodies as detoxication agents.

Abstract
Aflatoxin (AF) contamination presents one of the most insidious challenges to combat, in food safety. Its adulteration of agricultural commodities presents an important safety concern as evident in the incidences of its health implication and economic losses reported widely. Due to the overarching challenges presented by the contamination of AFs in foods and feeds, there is an urgent need to evolve cost-effective and competent strategies to combat this menace. In our review, we tried to appraise the cost-effective methods for decontamination of AFs. We identified the missing links in adopting microbial degradation as a palliative to decontamination of AFs and its commercialization in food and feed industries. Cogent areas of further research were also highlighted in the review paper.

Toxins (Basel) 2018; 10:E25. [PMID: 29301315 PMCID: PMC5793112 DOI: 10.3390/toxins10010025] [Citation(s) in RCA: 70] [Impact Index Per Article: 11.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2017] [Revised: 12/28/2017] [Accepted: 12/28/2017] [Indexed: 12/21/2022] Open
Abstract
Aflatoxin B1 (AFB1), among other aflatoxins of the aflatoxin family, is the most carcinogenic and hazardous mycotoxin to animals and human beings with very high potency leading to aflatoxicosis. Selenium is an essential trace mineral possessing powerful antioxidant functions. Selenium is widely reported as an effective antioxidant against aflatoxicosis. By preventing oxidative liver damage, suppressing pro-apoptotic proteins and improving immune status in AFB1 affected animals; selenium confers specific protection against AFB1 toxicity. Meticulous supplementation of animal feed by elemental selenium in the organic and inorganic forms has proven to be effective to ameliorate AFB1 toxicity. Curcumin is another dietary agent of importance in tackling aflatoxicosis. Curcumin is one of the major active ingredients in the tubers of a spice Curcuma longa L., a widely reported antioxidant, anticarcinogenic agent with reported protective potential against aflatoxin-mediated liver damage. Curcumin restricts the aflatoxigenic potential of Aspergillusflavus. Curcumin inhibits cytochrome P450 isoenzymes, particularly CYP2A6 isoform; thereby reducing the formation of AFB1-8, 9-epoxide and other toxic metabolites causing aflatoxicosis. In this review, we have briefly reviewed important aflatoxicosis symptoms among animals. With the main focus on curcumin and selenium, we have reviewed their underlying protective mechanisms in different animals along with their extraction and production methods for feed applications.

Abstract
Aflatoxicosis is a grave threat to the poultry industry. Dietary supplementation with antioxidants showed a great potential in enhancing the immune system; hence, protecting animals against aflatoxin B1-induced toxicity. Grape seed proanthocyanidin extract (GSPE) one of the most well-known and powerful antioxidants. Therefore, the purpose of this research was to investigate the effectiveness of GSPE in the detoxification of AFB1 in broilers. A total of 300 one-day-old Cobb chicks were randomly allocated into five treatments of six replicates (10 birds per replicate), fed ad libitum for four weeks with the following dietary treatments: 1. Basal diet (control); 2. Basal diet + 1 mg/kg AFB1 contaminated corn (AFB1); 3. Basal diet + GSPE 250 mg/kg; (GSPE 250 mg/kg) 4. Basal diet + AFB1 (1 mg/kg) + GSPE 250 mg/kg; (AFB1 + GSPE 250 mg/kg) 5. Basal diet + AFB1 (1mg/kg) + GSPE 500 mg/kg, (AFB1 + GSPE 500 mg/kg). When compared with the control group, feeding broilers with AFB1 alone significantly reduced growth performance, serum immunoglobulin contents, negatively altered serum biochemical contents, and enzyme activities, and induced histopathological lesion in the liver. In addition, AFB1 significantly increased malondialdehyde content and decreased total superoxide dismutase, catalase, glutathione peroxide, glutathione-S transferase, glutathione reductase activities, and glutathione concentration within the liver and serum. The supplementation of GSPE (250 and 500 mg/kg) to AFB1 contaminated diet reduced AFB1 residue in the liver and significantly mitigated AFB1 negative effects. From these results, it can be concluded that dietary supplementation of GSPE has protective effects against aflatoxicosis caused by AFB1 in broiler chickens.
