“…The core purpose of integrating synbiotics into diets is to enhance disease resistance by activating fish immunity (Dawood et al, ). Our results are in accordance with those of Firouzbakhsh, Mehrabi, Heydari, Khalesi, and Tajick () who observed significantly reduced mortality rates in Biomin‐treated rainbow trout ( O. mykiss ) challenged with Saprolegnia parasitica . Similarly, Kumar et al () observed high resistance against A. hydrophila in Cirrhinus mrigala juveniles fed synbiotic additives.…”

This study investigated the effects of a synbiotic Lacto Forte on growth performance, haemato-immunological responses, plasma bactericidal capacity, histological profiles and resistance of Oreochromis niloticus to Pseudomonas fluorescens. The experimental fish were divided into three groups; two of them (T1 and T2) were given Lacto Forte incorporated diets at increasing level (0.7 and 1.5 g/kg, respectively) and an additive-free basal diet served as the control (T0) for 30 and 45 days. At the end of the feeding trial, a challenge was performed using a virulent strain of P. fluorescens and mortalities were recorded over an additional 14-days period. The results showed that Lacto Forte has a pronounced effect on haematological and growth performance parameters at 1.5 g/kg rather than 0.5 g/kg (p < 0.05). Plasma lysozyme, proteases, antiproteases and bactericidal capacity were significantly enhanced (p < 0.05) in Lacto Forte-treated groups, particularly after 45 days of supplementation. Long-term supplementation with Lacto Forte (1.5 g/kg) induced degenerative changes in the liver, spleen and intestine. Additionally, a significant increase (p < 0.05) in survival rates were found in Lacto Forte-treated groups compared to the control one 14 days post-challenge. As a result, Lacto Forte fortifies tilapia immune response and can be used as a surrogate for antibiotics to control P. fluorescens.

“…Sheikhzadeh and Heidarieh [21] declared that synbiotic Biomin ® IMBO could improve the growth performance and skin mucus immunity in Carassius carassius. Firouzbakhsh et al [64] reported in rainbow trout (Oncorhynchus mykiss) significant increases in FW and SGR at all experimental treatments. In their study, the best FCR, and maximum SR were observed in fish fed with 1% synbiotic supplemented diet.…”

This study was carried out to evaluate combined and singular effects of ethanolic extract of Persian shallot (Allium hirtifolium Boiss) and synbiotic Biomin®IMBO on growth performance, innate immune responses, and antioxidant defense in zebrafish (Danio rerio). Fish with initial weight of 151.90 ± 0.31 mg were allocated in 21 10-L glass aquariums. The experimental groups were as follows: T1, control (without any supplementation); T2, 1% synbiotic; T3, 3% synbiotic; T4, 1% Persian shallot (as a medical plant); T5, 3% Persian shallot; T6, 1% Persian shallot and 1% synbiotic; T7, 3% Persian shallot and 3% synbiotic. At the end of the experiment (60 days), all treatments significantly showed higher final weight (FW), weight gain (WG), WG (%), and specific growth rate (SGR) compared with the fish fed on control diet. Furthermore, both synbiotic Biomin®IMBO and Persian shallot significantly improved intestine immune parameters including lysozyme, alternative complement hemolytic activity (ACH50), total immunoglobulin (total Ig), and myeloperoxidase (MPO) of zebrafish compared to fish fed on control diet (p < 0.05). Also, in all experimental groups, hepatic catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx), and glutathione reductase (GR) activities significantly increased compared to the control group. Whereas, the highest MDA level was observed in the control group compared to the treatments (p < 0.05). Moreover, skin mucus immune parameters of zebrafish have been noticeably improved with synbiotic Biomin®IMBO and Persian shallot compared to fish fed on the control diet (p < 0.05). The results indicate that synbiotic or Persian shallot supplemented diet could enhance the general health status of the zebrafish.

“…Artificial infection with S . parasitica zoospores in fish was carried out following Firouzbakhsh, Mehabi, Heydari, Khalesi, and Tajick () method with slight modification (Saha, Pal, Sahu, & Saha, ). To allow penetration of zoospores inside fish body, prevention of mucus layer and stress induction was done following Hatai and Hoshiai ().…”

This study evaluated the effect of sublethal doses of antifungal drug miconazole nitrate (MCZ) on immunological responses and its role as a prophylactic drug against S. parasitica in Labeo rohita fingerlings. Fish were fed with sublethal doses of MCZ, that is, T1-6.30 mgMCZ kgBW , T2-12.61 mgMCZ kgBW and T3-25.22 mgMCZ kgBW , and sampling was done at different time intervals for 240 hr. Immunological parameters viz. lysozyme activity, oxygen radical production and plasma antiprotease activity showed significant enhancement (p < 0.05) in fish fed with T2 and T3 doses. Expression of immune-relevant genes such as TLR-22 and β2-M showed significantly higher expression at 6 hr and 24 hr of sampling in both liver and head kidney. However, these genes showed a downregulation after 120 hr of sampling in both the tissues. Preventive efficacy study showed that single dose of MCZ provides protection against oomycetes up to the fourth day of infection. Significantly higher mortality was observed in control diet-fed fish as compared to fish fed with MCZ medicated diet. Thus, it can be concluded that the MCZ can act as a potent antifungal agent for preventing oomycetes infection as well as to enhance the immune response.
