“…This concept was consistent with our observation; there were higher survival in the groups of fish with the higher antibody titers and these fish were more common in the NB-O3 treatment group [27]. The results obtained in this study are in agreement with a previous study, which induced significant protection in Asian seabass (Lates calcarifer), demonstrated by an RPS value ranging from 75-85% in both monovalent and bivalent vaccine groups after challenge with the inactivated S. agalactiae and S. iniae [42] or better RPS value (59.3 59.3% and 77.8%) was achieved with fish in the vaccinated group supplemented with adjuvants (aluminum hydroxide and FIA) compared with fish in the other groups without adjuvants [44]. Our previous study reported that pre-treatment with NB-O3 stimulated expression of immune-related genes of the fish innate immune system [27].…”

Nanobubble technology has shown appealing technical benefits and potential applications in aquaculture. We recently found that treatment with ozone nanobubbles (NB-O3) activated expression of several immune-related genes leading to effective response to subsequent exposure to fish pathogens. In this study, we investigated whether pre-treatment of Nile tilapia (Oreochromis niloticus) with NB-O3 can enhance specific immune responses and improve efficacy of immersion vaccination against Streptococcus agalactiae. Spleen and head kidney of fish in the vaccinated groups showed a substantial upregulation in expression levels of three immunoglobulin classes(IgM, IgD, and IgT) compared with the unvaccinated control groups. At day 21 post-immunization, the relative expression was greatest (approx. 3.2 to 4.1 folds). Both systemic and mucosal IgM antibodies were elicited in vaccinated groups. As the result, the cumulative survival rate of the vaccinated groups was found to be higher than that of the unvaccinated groups, with a relative percent survival (RPS) ranging from 52.9-70.5%. However, fish in the vaccinated groups that received pre-treatment with NB-O3, bacterial antigen uptakes, expression levels of IgM, IgD, and IgT, as well as the specific-IgM antibody levels and percent survival, were all slightly or significantly higher than that of the vaccinated group without pre-treatment with NB-O3. Taken together, our findings suggest that utilizing pre-treatment with NB-O3 may improve the immune response and efficacy of immersion vaccination in Nile tilapia.HighlightsImmune response and efficacy of a heat-killed Streptococcus agalactiae immersion vaccine for Nile tilapia with and without pre-treatment with NB-O3 were accessed.Bacterial antigen uptake in the NB-O3-VAC compared to the AT-VAC groups was increased 1.32 and 1.80-fold at 3 and 6 h post-vaccination, respectively.Vaccinated group that received pre-treatment with NB-O3 had slightly to significantly higher levels of IgM, IgD, and IgT mRNA expression; IgM levels; and survival rate.Pre-treatment with NB-O3 may be a novel strategy for improving efficacy of immersion vaccine in aquaculture

The growth, immune response, and reproductive performance of broodstock of Nile tilapia (Oreochromis niloticus) under winter stress conditions were investigated the effects of supplementary diets with astaxanthin-enriched bacterium, Paracoccus carotinifaciens. Throughout an eight-week period in the winter season, male and female tilapia were fed with diets containing different levels of P. carotinifaciens dietary supplementation: 0 g/kg (T1; control), 5 g/kg (T2), 10 g/kg (T3), and 20 g/kg (T4). Subsequently, a four-week mating system was implemented during the winter stress period. The results revealed that there were no signi cant differences observed in growth, hematological indices, and blood chemical pro les among all treatment groups for both male and female tilapia. However, a signi cant increase in cholesterol content was noted in both male and female tilapia fed with the T4 diet (p<0.05). The total carotenoid content in the muscle was evaluated, and signi cantly higher values were found in both male and female tilapia that fed T4 supplementation (p<0.05). Moreover, immunological parameters such as myeloperoxidase and antioxidant parameters in the liver including superoxide dismutase activity and catalase enzyme activity showed signi cant increases in tilapia fed with the T4 diet. The impact of P. carotinifacienssupplementation on broodstock tilapia indicated a signi cant increase in spermatozoa concentration in males and increased egg production in females after consumption of the T4 diet (p<0.05). Thus, this study highlighted that the presence of astaxanthin-enriched bacterium P. carotinifaciensin the diet of broodstock Nile tilapia can lead to the accumulation of carotenoids in their muscle tissue, improvement in antioxidant status, enhancement of immune function, and potential enhancement of reproductive capabilities, even under overwintering conditions.
