Effects of dietary Lactococcus lactis Z-2 on growth, host health and resistance to Aeromonas hydrophila in juvenile common carp (Cyprinus carpio L.). JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2025. [PMID: 39831325 DOI: 10.1002/jsfa.14136] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/16/2024] [Revised: 11/24/2024] [Accepted: 01/07/2025] [Indexed: 01/22/2025]
Abstract
BACKGROUND Lactococcus lactis Z-2 was previously isolated from common carp intestine. In order to investigate the effects of optimal dose of L. lactis Z-2 on growth, host health and disease resistance to Aeromonas hydrophila in common carp, five experimental diets, including without (CK and CK+ groups) or with 5 × 107 (group A), 5 × 108 (group B) and 5 × 109 CFU g-1 (group C) L. lactis Z-2, were evaluated for 8 weeks. RESULTS Supplementation of L. lactis Z-2 increased final weights, weight gain, specific growth rate, condition factor and muscle crude protein content, while feed conversion ratio, muscle crude lipid and ash contents were lower than in the CK group (P < 0.05). Furthermore, L. lactis Z-2 also promoted intestinal digestive enzyme (lipase, amylase, protease) activities, improved intestinal morphology and upregulated gene (ZO-1, Occludin, Claudin) expression of intestinal barrier; stimulated secretion of proinflammatory (IL-6, IL-1β, TNF-α) and anti-inflammatory cytokines (TGF-β, IL-10) in serum; and boosted AKP, ACP, LZM and antioxidant enzyme (T-AOC, GSH-Px, T-SOD, CAT) activities of hepatopancreas (P < 0.05). Among them, the effect of group B was more prominent. After A. hydrophila infection, the CK+ group showed overexpression of immune indicators and decreased antioxidant capacity. Whereas dietary intervention with L. lactis Z-2 significantly reversed these changes. Moreover, the survival rate was significantly higher (100%) in group B than in the CK+ group (36.36%) after A. hydrophila infection (P < 0.05). CONCLUSION Dietary L. lactis Z-2 improved the growth performance, immune response, antioxidant capacity, intestinal health and disease resistance of juvenile common carp. Ultimately, 5 × 108 CFU g-1 dietary L lactis Z-2 is recommended for the formulation of feed. © 2025 Society of Chemical Industry.

Dietary tea tree (Melaleucae Aetheroleum) oil fortifies growth, biochemical, immune-antioxidant trait, gene function, tissue reaction, and Aeromonas sobria resistance in Nile tilapia (Oreochromis niloticus). BMC Vet Res 2025; 21:1.

Abstract
The current study had aimed to assess the long-term dietary supplementation with Melaleucae aetheroleum, tea tree essential oil (TTO). The impact on growth performance, biochemical indices, immune function, oxidant/antioxidant activity, gene expression, histopathology, and resistance against Aeromonas sobria in Nile tilapia (Oreochromis niloticus) was investigated. Four groups (with five replicates; G1 (control group, G2, G3, and G4) of Nile tilapia received diets enriched with TTO (doses of 0.0, 0.5, 1.0, and 2.0 mL/kg diet) for 60 days, then fish were challenged by A. sobria. Outcomes indicated an extensive elevation in growth metrics (final body weight, weight gain, SGR, feed intake and fish body protein). Similarly, the total blood protein, albumin, total globulin levels, Serum complement-3 levels, lysozyme activity, immunoglobulin M (IgM), nitric oxide, and phagocytic activity were significantly enhanced in all treatments, notably in the 2.0 mL TTO/kg fed groups compared to the control. Lower levels of urea, creatinine, AST, ALP, ALT, cortisol, glucose, triglycerides, cholesterol and body crude lipids were observed in the fish that were fed a 2.0 mL TTO/kg diet. Supplementing TTO at 2.0-mL /kg diet revealed the best results for elevating CAT, SOD, and GSH activities plus declining MDA value in hepatic homogenate. Additionally, dietary 2.0-mL TTO/kg showed the best outcomes for the intestinal morphometry plus maintaining the histological picture in spleen and liver. Concurrently, fish that were fed a 2.0 mL TTO/kg diet exhibited a substantial upregulation of TNF-α, IL-1β, IL-10, TFG-β, IFN-γ and BCL-2 genes in the liver, while, caspase-3, and BAX were downregulated. Furthermore, TTO-enriched diets enhanced the relative percentage survival post-A. sobria challenge plus enhanced the clinical picture in a dose-dependent manner. Taken together, the findings revealed that long-term exposure to dietary TTO fortified the physiological performance, oxidant/anti-oxidant stability, immune function, gene expression, histological picture, and resistance of Nile tilapia against A. sobria.

Abstract
Acne vulgaris is an inflammatory dermatological pathology that affects mostly young people. However, it can also appear in adulthood, mainly in women. It has a high psychosocial impact, not only at the time of active lesions but also due to the consequences of lesions such as scarring and hyperpigmentation. Several factors are involved in the physiopathology of acne and the constant search for active ingredients is a reality, namely phytotherapeutic ingredients. Tea tree oil is an essential oil extracted from Melaleuca alternifolia (Maiden & Betch) Cheel with known antibacterial, anti-inflammatory, and antioxidant properties, making it a candidate for the treatment of acne. This review aims to describe the various properties of tea tree oil that make it a possible ingredient to use in the treatment of acne and to present several human studies that have evaluated the efficacy and safety of using tea tree oil in the treatment of acne. It can be concluded that tea tree oil has good antibacterial, anti-inflammatory, and antioxidant properties that result in a decrease in the number of inflammatory lesions, mainly papules, and pustules. However, given the diversity of study designs, it is not possible to draw concrete conclusions on the efficacy and safety of this oil in the treatment of acne.

Abstract
The use of essential oils (EOs) as a natural alternative to antibiotics for disease prevention strategies is gaining much interest in recent decade. Coriander (Coriandrum sativum L.) essential oil is rich in bioactive compounds like linalool and geranyl acetate which have antioxidant, anti-inflammatory and antimicrobial activities. The present work was proposed to evaluate the inclusion levels of coriander oil in tilapia feed to enhance tilapia health and resistance to bacterial infection. Five iso-nitrogenous and iso-lipidic feeds were prepared with graded levels of coriander oil (0, 0.5, 1, 1.5 and 2%). The fish were then fed with the five experimental diet twice daily for a period of 60 days in triplicate. Haemoglobin, mean corpuscular volume, mean cell haemoglobin increased significantly in the coriander oil treated groups. The thrombocyte count was more in 2% inclusion level. The superoxide dismutase activity increased significantly in all the treated groups. The feeds with 1.5 and 2% coriander oil showed increased respiratory burst and myeloperoxidase activities while lysozyme and antiprotease activities were significantly higher in 1, 1.5 and 2% dietary treatments compared to control. The survival increased in dose dependent manner post challenge with an intraperitoneal injection of Aeromonas hydrophila at a LD50 dose of 5 × 106 cfu mL-1. The feed containing 1, 1.5 and 2% of coriander oil showed 89, 100 and 100% survival respectively compared to 39% in control diet. The expression level of IgM and IL-8 increased significantly post challenge with A. hydrophila in coriander oil fed groups. The expressions of TNFα, IL-1β, TGFβ and HSP 70 genes, however, decreased significantly in the treated groups compared to control. Histopathological examination of spleen showed large melano-macrophage centers in control and 0.5% coriander fed group with signs of necrosis and vacuolation post A. hydrophila infection, whereas 1, 1.5 and 2% treated groups showed normal architecture of spleen. From the above observations it can be concluded that coriander oil with 1% incorporation in feed improves tilapia health and resistance to bacterial infection.

Protective role of rutin dietary supplementation mediated by purinergic signaling in spleen of silver catfish Rhamdia quelen exposed to organophosphate pesticide trichlorfon. Comp Biochem Physiol C Toxicol Pharmacol 2021; 244:109006. [PMID: 33610818 DOI: 10.1016/j.cbpc.2021.109006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/23/2020] [Revised: 01/28/2021] [Accepted: 02/11/2021] [Indexed: 10/22/2022]
Abstract
Evidence suggests the involvement of purinergic signaling, a mechanism mediated by extracellular nucleotides and nucleosides, with the impairment of immune and inflammatory responses in silver catfish (Rhamdia quelen) exposed to trichlorfon. Plant-derived substances have been considered potent anti-inflammatory agents due to effects on the purinergic system, such as the use of the flavonoid rutin. The aim of this study was to determine whether a diet containing rutin is able to prevent or reduce trichlorfon-induced impairment of immune responses through alteration of the purinergic pathway. Spleen adenosine triphosphate (ATP) levels were significantly higher in silver catfish exposed to 11 mg/L trichlorfon for 48 h compared to the control group, while adenosine (Ado) levels were significantly lower. Spleen ectonucleoside triphosphate diphosphohydrolase (NTPDase) activity was significantly lower in silver catfish exposed to trichlorfon compared to control group, while adenosine deaminase activity was significantly higher. Spleen metabolites of nitric oxide, interleukin-1, and IL-6 were significantly higher in silver catfish exposed to trichlorfon compared to control group. Diet with 3 mg rutin/kg diet was able to prevent all the alterations elicited by trichlorfon, except restoring spleen ATP levels. The purinergic exposure signaling is involved in impairment of immune and inflammatory responses in fish exposed to trichlorfon due to reduction in ATP hydrolyses and by an increase in Ado deamination, leading to release of pro-inflammatory mediators. Use of rutin-added diet exerted an essential role in protecting the silver catfish spleen from trichlorfon-induced impairment on immune and inflammatory responses, preventing all alterations on splenic purinergic signaling.

Abstract
The objective of this study was to determine whether dietary tea tree oil (TTO) supplementation could effectively replace the antibiotics through modulating the antioxidant capacity and intestinal microbiota profile, and then decreasing the diarrhoea incidence and improving the growth performance of weaned pigs. A total of 216 weaned pigs with initial body weights (BW) of 9.19 ± 1.86 kg were randomly allocated to three dietary treatments in a completely randomised design. The dietary treatments included a corn-soybean meal basal diet (CON) without any antibiotics, and two experimental diets formulated by adding 75 mg/kg aureomycin (AGP) or 100 mg/kg TTO into the basal diet, respectively. Pigs fed the TTO diet showed greater gain to feed ratio (p < 0.05) than those fed CON and AGP diets during d 0-14 and d 14-28. Both dietary TTO and AGP supplementation tended to increase the average daily gain of weaned pigs during d 14-28 (p = 0.06) and the overall 28-d period (p = 0.07), and significantly reduced (p < 0.05) the diarrhoea incidence during d 0-14 compared with the CON treatment. In addition, dietary TTO supplementation improved the apparent total tract digestibility of dry matter and ether extract (p < 0.05), and increased (p < 0.05) the propionate and butyrate concentrations in faecal samples of weaned pigs. Moreover, pigs fed the TTO diet showed greater total antioxidant capacity, greater superoxide dismutase and interleukin-10 concentrations, and lower malondialdehyde concentration in serum than those fed the CON diet (p < 0.05). Furthermore, pigs fed the TTO diet demonstrated greater relative abundance of Clostridiaceae_1, while those fed the AGP diet exhibited greater relative abundance of Lactobacillaceae at family level. In conclusion, dietary TTO supplementation could improve growth performance in weaned pigs, which could be mainly attributed to the benefits on nutrient digestibility, antioxidative capacity and microbial community profile.

Abstract
A viscous solution of low molecular weight chitosan (CH) at 5% w/v (10.2 kDa, 75 % deacetylated, 1451 cP at 25 °C) was associated with a microemulsion (ME) that undergoes a phase transition after water absorption in situ (≈28 % w/w), forming a more viscous liquid crystal, which was potentially evaluated as a topical vehicle. The ME was selected from a phase diagram, selecting a composition based on Tween® 80 (52 %), myristate isopropyl (28 %), and the aqueous phase (water and polyethylene glycol 400, 60:40 w/w) (20 %), which was after replaced by CH and herbal medicines (HM). HM are alternatives to treat candidiasis, and Stryphnodendron adstringens shell extract, characterized by molecular networking, and Melaleuca alternifolia Chell essential oil (46 % of terpinen-4-ol), showed in vitro activity against Candida albicans. Associating CH in ME improved the mechanical properties of the topical formulation, as adhesiveness, which is an advantageous feature for the topical treatment of vulvovaginal candidiasis.

Purine levels and purinergic signaling in plasma and spleen of Brycon amazonicus exposed to acute heat thermal stress: An attempt to regulate the immune response. J Therm Biol 2020; 89:102569. [PMID: 32364972 DOI: 10.1016/j.jtherbio.2020.102569] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2019] [Revised: 02/20/2020] [Accepted: 03/15/2020] [Indexed: 12/12/2022]
Abstract
Amazon fish are vulnerable to climate change. Several lines of evidence suggest that the temperature of Amazonian rivers will increase in the coming years. Elevated temperature disturbs homeostasis and subjects fish to physiological stress; however, the effects of temperature on immunity remain poorly understood, particularly those effects involving purinergic signaling. This system fine-tunes the inflammatory and immune responses triggered by stress. Therefore, the aims of this study were to determine whether acute heat stress induces the release of nucleotides into extracellular compartment and to determine whether purinergic enzymes modulate the proinflammatory effects of adenosine triphosphate (ATP) in plasma and spleen of matrinxã (Brycon amazonicus) exposed to acute heat stress. We exposed juvenile matrinxã to four temperature regimes (28 °C as control, 30, 32 and 34 °C) for 72 h and observed the effects on purinergic signaling. Plasma cortisol levels were significantly higher in fish exposed to 34 °C than in the control group, while spleen ATP, adenosine diphosphate (ADP) and adenosine monophosphate (AMP) levels were significantly higher in this group than in controls. Activities of spleen nucleoside triphosphate diphosphohydrolase (NTPDase) and 5'-nucleotidase were significantly higher in fish exposed to 34 °C than those of the control group, while spleen interleukin-1 (IL-1) and interleukin-6 (IL-6) levels were higher in this same group than in the control group. No significant differences were observed between the groups regarding plasma parameters. Based on these data, we concluded that acute heat stress at 34 °C caused physiological stress in matrinxã, manifesting as elevated plasma cortisol levels. The most important finding is that purinergic enzymes were modulated, though not efficiently, in response to the excessive release of nucleotides into the extracellular space. In summary, the purinergic signaling pathway may be involved in the impairment of immune and inflammatory responses in matrinxã exposed acutely to 34 °C.

Abstract
A trial was operated to assess the potential of using Lactobacillus plantarum L-137 (L-137) and/or β-glucan (BG) in improving the resistance of Nile tilapia against Aeromonas hydrophila. Control diet and 3 diets supplemented with L-137, BG or L-137 + BG were prepared. Final body weight, specific growth rate, superoxide dismutase, and catalase showed considerably (P < .05) increased values in L-137 or L-137/BG groups, while glutathione peroxidase increased significantly (P < .05) only in L-137/BG group. Fish fed L-137 and/or BG diets showed that feed conversion ratio and malonaldehyde levels were significantly decreased (P < .05). Also, both L-137 and BG helped Nile tilapia to have high phagocytosis activity and relative expression of tumor necrosis factor-alpha (TNF-α) and interleukin 1 beta (IL-1β) and interferon-gamma (INF-γ) genes. After A. hydrophila challenge, the intestinal villi epithelium of the L-137/BG group was intact and denser than the other groups. The hepatopancreas and spleen of the control group displayed severe necrosis in hepatocytes and congestion of blood sinusoids in addition to diffuse vacuolation. Regarding the L-137, BG and L-137/BG groups, there was a moderate and normal degree of vacuolation with focal necrosis and mild to moderate degree of congestion of blood sinusoids. Red blood cells, hemoglobin, and albumin showed meaningfully (P < .05) increased values in L-137 or L-137/BG groups. TNF-α, IL-1β, and INF-γ expressions were upregulated by L-137 and/or BG. The obtained results revealed the ability of L-137 and/or BG to protect Nile tilapia from the effects of A. hydrophila infection by the motivation of the immune, antioxidative, and antiinflammation responses.

Purinergic signaling and gene expression of purinoceptors in the head kidney of the silver catfish Rhamdia quelen experimentally infected by Flavobacterium columnare. Microb Pathog 2020; 142:104070. [PMID: 32081613 DOI: 10.1016/j.micpath.2020.104070] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2019] [Revised: 02/12/2020] [Accepted: 02/13/2020] [Indexed: 01/21/2023]
Abstract
The head kidney is a lymphoid immune organ that plays a key role in the immune and inflammatory responses of teleost fish. It is associated with immunoglobulin G production and differentiation of B cells. The presence of a multi-enzymatic complex found anchored in the plasma membrane makes the head kidney an important purinergic-dependent tissue. Purinergic signaling has been associated with these responses under pathological conditions via regulation of extracellular adenosine triphosphate (ATP), the main damage molecular associated pattern agent released during bacterial infections. The aim of this study was to determine whether purinergic signaling is a pathway associated with impairment of immune responses in silver catfish (Rhamdia quelen) experimentally infected by Flavobacterium columnare, as well as to evaluate the role of P2 purine receptors in this response. Triphosphate diphosphohydrolase (NTPDase) activity in the head kidney was significantly lower in silver catfish experimentally-infected F. columnare 72 h post-infection (hpi) than in the control group, while no significant difference was observed with respect NTPDase activity on adenosine diphosphate, as well as on 5'-nucleotidase and adenosine deaminase activities. Extracellular ATP levels were significantly higher in the head kidney of experimentally-infected fish than in the control group at 72 hpi. Finally, p2ry11 and p2rx3 purine receptor levels were significantly higher in experimentally-infected fish than in the control group at 72 hpi. We conclude that purinergic signaling in the head kidney of silver catfish infected by F. columnare creates a pro-inflammatory profile that may contribute to impairment of immune and inflammatory responses via reduction of ATP hydrolysis and its accumulation in the extracellular milieu, accompanied by upregulation of p2ry11 and p2rx3 purine receptors, leading to pro-inflammatory status.

Abstract
In fish, stressful events initiate a hormone cascade along the hypothalamus-pituitary-interrenal and hypothalamus-sympathetic-chromaffin (HSC) axis to evoke several physiological reactions in order to orchestrate and maintain homeostasis. Several biotic and abiotic factors, as well as aquaculture procedures (handling, transport, or stocking density), activated stress system inducing negative effects on different physiological processes in fish (growth, reproduction, and immunity). In order to reduce these consequences, the use of essential oils (EOs) derived from plants has been the focus of aquaculture studies due to their diverse properties (e.g., anesthetic, antioxidant, and antimicrobial), which have been shown to reduce biochemical and endocrine alterations and, consequently, to improve the welfare status. Recently, several studies have shown that biogenic compounds isolated from different EOs present excellent biological activities, as well as the nanoencapsulated form of these EOs may potentiate their effects. Overall, EOs presented less side effects than synthetic compounds, but their stress-reducing efficacy is related to their chemical composition, concentration or chemotype used. In addition, their species-specific actions must be clearly established since they can act as stressors by themselves if their concentrations and chemotypes used are not suitable. For this reason, it is necessary to assess the effect of these natural compound mixtures in different fish species, from marine to freshwater, in order to find the ideal concentration range and the way for their administration to obtain the desired biological activity, without any undesired side effects. In this review, the main findings regarding the use of different EOs as stress reducers will be presented to highlight the most important issues related to their use to improve fish welfare in aquaculture.

Abstract
Aquaculture suffers from a number of diseases caused by Aeromonas hydrophila. Biofilm can protect bacteria from antibiotic therapy. To identify the genes those play crucial roles in A. hydrophila biofilm formation, a library of mini-Tn10 transposon insertion mutants of A. hydrophila B11 has been constructed, and 10 mutants were subjected to biofilm formation assay. The biofilm formation ability of mutant (B188) was significantly decreased compared with B11. The DNA sequence flanking the mini-Tn10 transposon inserted showed that an ORF of approximately 576 bp of the mutant strain B188 was inserted. This ORF putatively displays the highest identity (92%) with the cytochrome c4 gene (cyt-c4) of A. hydrophila subsp. hydrophila ATCC 7966. Silencing cyt-c4 led to deficiencies in biofilm formation, adhesion, drug resistance and pathogenicity of A. hydrophila, which suggests that cyt-c4 plays crucial role in the biofilm formation and virulence mechanisms of A. hydrophila.

Abstract
The aim of this work is to identify the chemical constituents and the bioactivity of essential oil (EO), acetone extract (ACE) and n-hexane extract (HexE) of S. terebinthifolius ripened fruits using GC-MS. Total phenolic content and antioxidant activity of extracts were determined using the Folin-Ciocalteu and 1,1-diphenyl-2-picryl-hydrazyl (DPPH) assays, respectively. The toxicity against the growth of Acinetobacter baumannii, Bacillus subtilis, Escherichia coli, Micrococcus flavus, Pseudomonas aeruginosa, Sarcina lutea, and Staphylococcus aureus was determined with measuring the inhibition zones (IZs) using the disc diffusion method at the concentrations from 125 to 2000 μg/mL, also, the minimum inhibitory concentrations (MICs) using 96-well micro-plates and ranged from 4 to 2000 μg/mL. The major components in EO were α-pinene (36.9%), and α-phellandrene (32.8%). The major components in ACE were oleic acid (38.7%), α-phellandrene (13.33%), and δ-cadinene (11.1%), while the major methyl esters of fatty acids detected in HexE were oleic (12.8%), and palmitic (10.9%). The EO showed good activity against the growth of Staph. aureus and P. aeruginosa with MIC values of 16 μg/mL and 32 μg/mL, the ACE showed broad activity against the studied bacterial pathogens with MIC values ranged from of 4-128 μg/mL against the studied bacterial isolates, while HexE, however, showed weak antibacterial activity. The IC50 values of EO, ACE and HexE were 15.11 ± 0.99, 118.16 ± 1.7 and 324.26 ± 2.45 μg/mL, respectively, compared to IC50 of Tannic acid (23.83 ± 1.9 μg/mL) and butylated hydroxytoluene (BHT, 2.9 ± 0.1 μg/mL). Data suggested that the ripened fruits of S. terebinthifolius have potent antioxidant and antibacterial activities.

Purinergic signalling displays an anti-inflammatory profile in the spleen of fish experimentally infected with Aeromonas caviae: Modulation of the immune response.

Abstract
Extracellular adenosine triphosphate (ATP) and its metabolite adenosine (Ado) are recognized as key mediators of immune and inflammatory responses. Depending on its concentration, ATP may act as an immunostimulant or immunodepressant, while Ado levels display an anti-inflammatory profile. The aim of this study was to evaluate whether splenic purinergic signalling is capable of modulating immune and inflammatory responses in fish experimentally infected with Aeromonas caviae. Triphosphate diphosphohydrolase (NTPDase) and 5'-nucleotidase activities increased in the spleen of silver catfish (Rhamdia quelen) experimentally infected with A. caviae compared with the uninfected control group. Moreover, splenic Ado levels increased in the infected animals relative to the uninfected control group. Based on these lines of evidence, our findings revealed that adenine nucleotide hydrolysis is modified in the spleen of fish infected with A. caviae attempting to restrict the inflammatory process through the upregulation of NTPDase and 5'-nucleotidase activities, which occurs in an attempt to hydrolyse the excessive ATP in the extracellular environment and rapidly hydrolyse AMP to form Ado. In summary, purinergic signalling can modulate immune and inflammatory responses during A. caviae infection.

Abstract
The spleen is an immune lymphatic organ linked with control of the immune response, which is important to fish health. Recent evidence has suggested the involvement of purinergic signaling in the modulation of immune and inflammatory responses through the nucleotide adenosine triphosphate (ATP) and the nucleoside adenosine (Ado), which are regulated by the enzymes nucleoside triphosphate diphosphohydrolase (NTPDase), 5'-nucleotidase, and adenosine deaminase (ADA). Thus, the aim of this study was to evaluate whether purinergic signaling can modulate the immune and inflammatory responses in the spleen of silver catfish (Rhamdia quelen) naturally infected with Ichthyophthirius multifiliis. Splenic NTPDase and 5'-nucleotidase activities increased in infected animals compared with uninfected animals, while the splenic ADA activity decreased. These data indicate that purinergic signaling can modulate the splenic immune and inflammatory responses through the regulation of ATP and Ado levels, which are known to participate in the physiological and pathological responses as pro-inflammatory and anti-inflammatory molecules, respectively. In summary, modulation of the splenic purinergic cascade has an anti-inflammatory role in reducing or preventing inflammatory damage.

Abstract
The purinergic system is recognized to modulate extracellular adenosine triphosphate (ATP) and related nucleotides through the activities of triphosphate diphosphohydrolase (NTPDase), 5'-nucleotidase, and adenosine deaminase (ADA), thereby playing an essential role in the immunoregulation of inflammatory and immune responses. Thus, the aim of this study was to evaluate whether the purinergic system can improve the inflammatory response in fish experimentally infected with Streptococcus agalactiae through the modulation of seric NTPDase, 5'-nucleotidase and ADA activities. Seric NTPDase (ATP as substrate) and 5'-nucleotidase activities increased in silver catfish experimentally infected with S. agalactiae compared with the uninfected control group, while seric ADA activity decreased. Based on this evidence, our findings suggest that regulation of adenine nucleotide hydrolysis occurs in an attempt to restrict the inflammatory process and improve the immune system by hydrolyzing excess extracellular ATP. On the other hand, downregulation of seric ADA activity may be an attempt to augment extracellular adenosine (a molecule with anti-inflammatory effects) levels. In summary, the purinergic system is capable of modulating the immune and inflammatory responses during fish streptococcosis.
