Abstract
Limosilactobacillus (L) fermentum (strains 139, 263, 296) is a novel probiotic mixture isolated from fruit processing by-products. The use of this formulation has been associated with improvements in cardiometabolic, inflammatory, and oxidative stress parameters. The present study evaluated the safety of a potential multi-strain probiotic by genotoxicity (micronucleus assay) and subchronic toxicity study (13-week repeated dose). In the genotoxicity evaluation, L. fermentum 139, 263, 296 did not increase the frequency of micronuclei in erythrocytes of rats of both sexes at doses up to 1010 CFU/mL. In the subchronic toxicity study, the administration of L. fermentum did not promote adverse health effects, such as behavioral changes, appearance of tumors, changes in hematological and biochemical parameters. In addition, higher doses of L. fermentum 139, 263, 296 have been shown to reduce the levels of pro-inflammatory cytokines. Administration of potentially probiotic L. fermentum did not promote adverse health effects in rats and could be evaluated as a potential probiotic for humans.

Heliyon 2024; 10:e24691. [PMID: 38304811 PMCID: PMC10831734 DOI: 10.1016/j.heliyon.2024.e24691] [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: 04/20/2023] [Revised: 01/11/2024] [Accepted: 01/12/2024] [Indexed: 02/03/2024] Open
Abstract
Background & aims Probiotics are alive and beneficial bacteria used as food complements with sufficient amounts to improve and balance the intestinal flora in the human gastrointestinal tract and inhibit harmful microorganisms. In this study, we conducted experiments to evaluate he safety and the effect of one of our probiotics on selected biochemical parameters in animal models. Methods LabMix is a probiotic product containing three bacterial strains, including Lactobacillus acidophilus LA 304.17, Lactobacillus casei LC 304.08, and Bifidobacterium bifidum BF 304.98, with a density of 9 × 109 CFU/g and being mixed with suitable excipients. In this study, we conducted experiments to evaluate LabMix's acute ttoxicity in mice as well as subchronic toxicity in rats. Results The LD50 dose in mice of this product could not be determined since no death or disorder was recorded. In rats receiving LabMix with doses of 2.52 × 109 CFU/kg and 12.6 × 109 CFU/kg continuously for 28 days, this product caused no significant changes in the amount of red and white blood cells and platelets. Similarly, no significant changes were recorded in serum concentrations of hemoglobin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), glucose, protein, cholesterol, bilirubin, and creatinine. Besides, LabMix products also did not cause any changes in the histology of the liver, kidney, and spleen in rats. Moreover, LabMix was well tolerated without affecting the normal growth and feeding of rats. Furthermore, LabMix also decreased serum cytokines and increased serum and gut mucosal IgA antibodies. Conclusions LabMix product is possibly considered safe for human., and this sproduct reduced the release of pro-inflammatory cytokines (IL-6 and TNF-α ), but increased IgA levels. However, it is necessary to further evaluate the product's effectiveness in the preclinical phase as well as in further phases before mass production and commercialization.

Int J Mol Sci 2023; 25:141. [PMID: 38203313 PMCID: PMC10779160 DOI: 10.3390/ijms25010141] [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: 10/31/2023] [Revised: 11/30/2023] [Accepted: 12/15/2023] [Indexed: 01/12/2024] Open
Abstract
Lactobacilli have been widely used as probiotics because of their benefits for intestinal health and physiological functions. Among a variety of Lactobacillus genera, Limosilactobacillus reuteri has been studied for its ability to exert anti-inflammatory functions and its role in controlling metabolic disorders, as well as the production of the antimicrobial compound reuterin. However, the effects and mechanisms of L. reuteri on enhancing immune responses in the immunosuppressed states have been relatively understudied. In this study, we isolated an immunomodulatory strain, namely, L. reuteri KBL346 (KBL346), from a fecal sample of a 3-month-old infant in Korea. We evaluated the immunostimulatory activity and hematopoietic function of KBL346 in macrophages and cyclophosphamide (CPA)-induced immunosuppressed mice. KBL346 increased the phagocytic activity against Candida albicans MYA-4788 in macrophages, and as biomarkers for this, increased secretions of nitric oxide (NO) and prostaglandin E2 (PGE2) were confirmed. Also, the secretions of innate cytokines (TNF-α, IL-1β, and IL-6) were increased. In CPA-induced immunosuppressed mice, KBL346 at a dosage of 1010 CFU/kg protected against spleen injury and suppressed levels of immune-associated parameters, including NK cell activity, T and B lymphocyte proliferation, CD4+ and CD8+ T cell abundance, cytokines, and immunoglobulins in vivo. The effects were comparable or superior to those in the Korean red ginseng positive control group. Furthermore, the safety assessment of KBL346 as a probiotic was conducted by evaluating its antibiotic resistance, hemolytic activity, cytotoxicity, and metabolic characteristics. This study demonstrated the efficacy and safety of KBL346, which could potentially be used as a supplement to enhance the immune system.

Abstract
Neurodegenerative disorders (ND) are a group of conditions that affect the neurons in the brain and spinal cord, leading to their degeneration and eventually causing the loss of function in the affected areas. These disorders can be caused by a range of factors, including genetics, environmental factors, and lifestyle choices. Major pathological signs of these diseases are protein misfolding, proteosomal dysfunction, aggregation, inadequate degradation, oxidative stress, free radical formation, mitochondrial dysfunctions, impaired bioenergetics, DNA damage, fragmentation of Golgi apparatus neurons, disruption of axonal transport, dysfunction of neurotrophins (NTFs), neuroinflammatory or neuroimmune processes, and neurohumoral symptoms. According to recent studies, defects or imbalances in gut microbiota can directly lead to neurological disorders through the gut-brain axis. Probiotics in ND are recommended to prevent cognitive dysfunction, which is a major symptom of these diseases. Many in vivo and clinical trials have revealed that probiotics (Lactobacillus acidophilus, Bifidobacterium bifidum, and Lactobacillus casei, etc.) are effective candidates against the progression of ND. It has been proven that the inflammatory process and oxidative stress can be modulated by modifying the gut microbiota with the help of probiotics. As a result, this study provides an overview of the available data, bacterial variety, gut-brain axis defects, and probiotics' mode of action in averting ND. A literature search on particular sites, including PubMed, Nature, and Springer Link, has identified articles that might be pertinent to this subject. The search contains the following few groups of terms: (1) Neurodegenerative disorders and Probiotics OR (2) Probiotics and Neurodegenerative disorders. The outcomes of this study aid in elucidating the relationship between the effects of probiotics on different neurodegenerative disorders. This systematic review will assist in discovering new treatments in the future, as probiotics are generally safe and cause mild side effects in some cases in the human body.

Abstract
Tomato (Lycopersicon esculentum) is one of the most popular and valuable vegetables in the world. The most common products of its industrial processing in the food industry are juice, tomato paste, various sauces, canned or sun-dried fruits and powdered products. Tomato fruits are susceptible to bacterial diseases, and bacterial contamination can be a risk factor for the safety of processed tomato products. Developments in bioinformatics allow researchers to discuss target probiotic strains from an existing large number of probiotic strains for any link in the soil-plant-animal-human chain. Based on the literature and knowledge on the "One Health" concept, this study relates to the suggestion of a new term for probiotics: "One Health probiotics", beneficial for the unity of people, animals, and the environment. Strains of Lactiplantibacillus plantarum, having an ability to ferment a broad spectrum of plant carbohydrates, probiotic effects in human, and animal health, as well as being found in dairy products, vegetables, sauerkraut, pickles, some cheeses, fermented sausages, fish products, and rhizospheric soil, might be suggested as one of the probable candidates for "One Health" probiotics (also, for "One Health-tomato" probiotics) for the utilization in agriculture, food processing, and healthcare.

Abstract
Lactobacillus delbrueckii subsp. lactis CIDCA is a new potential probiotic strain whose molecular basis attributed to the host's benefit has been reported. This study investigated the safety aspects of Lactobacillus delbrueckii subsp. lactis CIDCA 133 based on whole-genome sequence and phenotypic analysis to avoid future questions about the harmful effects of this strain consumption. Genomic analysis showed that L. delbrueckii subsp. lactis CIDCA 133 harbors virulence, harmful metabolites, and antimicrobial resistance-associated genes. However, none of these genetic elements is flanked or located within prophage regions and plasmid sequence. At a phenotypic level, it was observed L. delbrueckii subsp. lactis CIDCA 133 antimicrobial resistance to aminoglycosides streptomycin and gentamicin antibiotics, but no hemolytic and mucin degradation activity was exhibited by strain. Furthermore, no adverse effects were observed regarding mice clinical and histopathological analysis after the strain consumption (5 × 107 CFU/mL). Overall, these findings reveal the safety of Lactobacillus delbrueckii subsp. lactis CIDCA 133 for consumption and future probiotic applications.
