“…It indicates that neutrophils were not stimulated. A decreased IL‐12 gene expression was observed in rainbow trout treated with tetra after Aeromonas hydrophila infection (Bilen & Elbeshti, 2019). Moreover, a diminished IL‐12 transcript was also observed in rainbow trout treated with black cumin (Altunoglu et al., 2017).…”

“…To reduce the usage of antibiotics, application of immunostimulants seems to be one of the safest options in aquaculture. Recently, herbal immunostimulants such as tetra Cotinus coggyria powder and extract (Bilen et al., 2011; Bilen & Elbeshti, 2019), beard lichen Usnea barbata extract (Bilen, Sirtiyah, et al., 2019), Chenopodium album extract (Amhamed et al., 2018), lemon balm Melissa officinalis (Bilen, Altief, et al., 2020) and nettle ( Urtica dioica ) methanolic extracts (Bilen et al., 2014) have been found to be effective in fish against some important fish pathogens. However, the mode of utilization of immunostimulant in experimental studies remains to be another issue unaddressed.…”

This study investigated the effects of Greek juniper extract on immune responses of rainbow trout. In this experiment, 4 doses [0 (Control), 1 (J1), 4 (J4) and 8 (J8) mg/kg] of the extract were administered orally using an oral gavage twice a day for 14 days. Immune responses were measured on 7th and 14th days. On 14th day, Yersinia ruckeri was injected intraperitoneally to all fish of all groups. On 14th day, ORP in fish of J1 group increased significantly. Lysozyme activity (LA) was increased in J8 group on 7th day (p < .05). On 14th day, a significant decrease was determined in J1 and J4 treatments in LA. Myeloperoxidase activity was significantly decreased in all groups irrespective of sampling times (p < .05). Interleukin (IL)‐1β was significantly elevated in fish of J8 group on 7th day. IL‐8 increased in fish of J8 and J4 groups on 7th day of the study. IL‐12 gene expression was significantly up‐regulated in J8 fish group on 7th day, and in J4 fish group on 14th day. Survival rate was higher in J8 treatment compared to the control and other treatments (p < .05). The results suggest that Juniperus excelsa provides protection against Y. ruckeri in rainbow trout.

“…During the last decade, herbal‐derived immunostimulants have been widely used to enhance immunity in fish (Bilen & Elbeshti, 2019; Bilen et al, 2019; Bulfon et al, 2015; Hajirezaee et al, 2019; Rafieepour et al, 2019; Van Hai, 2015). Among these studies, some studies have also reported the effect of plant‐derived substances on prevention and modification of bacterial infections in fish (Divyagnaneswari et al, 2008; Ponnusamy et al, 2010; Sharma et al, 2010; Sivaram et al, 2004).…”

The immune-enhancing and antibacterial properties of Black cumin, Bunium persicum have been reported in the literatures. The present work examined the effects of black cumin essential oil (BEO) administration on immunity and resistance of rainbow trout, Oncorhynchus mykiss against the pathogen, Aeromonas hydrophila. To this end, fish were fed different levels of BEO [0%, 1% (10 g/kg diet), 2% (20 g/kg diet) and 3% (30 g/kg diet)] for 60 days. At the end of feeding trial, the growth parameters and immunological components of mucus and serum assayed and then fish challenged with A. hydrophila for an additional 10 days. No significant changes were observed in growth parameters (FCR, total weight gain, total final weight) between experimental groups after feeding period (p > 0.05). The BEO in 2% and 3% levels enhanced the serum and mucosal levels of lysozyme and bactericidal activity (p < 0.01). The serum immunoglobulin (Ig) levels, alternative complement activity (ACH50) and peroxidase activity elevated in fish administered 3% BPO (p < 0.01). Total albumin in blood, total protein in mucus and blood increased in all BPO-administered fish (p < 0.01). The mucosal protease and ALP activities elevated in fish fed 2% and 3% BPO (p < 0.01).The immune-related genes (iNOS and C3) were up-regulated in BEO-administered fish, with maximum expression in fish fed 3% BEO (p < 0.01). After the challenge with A. hydrophila, the IL-1b and TNFα expression significantly elevated in all groups (p < 0.01), although it was less pronounced in the EBO administrated fish. The diets containing 2% and 3% BEO significantly decreased the fish mortality following the challenge with A. hydrophila. In addition, less hepatocyte necrosis was observed in these treatments compared with the control group. Based on GC-Mass analysis of the essential oil, some components with antioxidant and antibacterial properties such as cuminaldehyde, ρ-cymene, limonene and γ-terpinene were recognized. In conclusion, the results of the present study demonstrated that dietary BEO can enhance immunity and increase the resistance of the rainbow trout against A. hydrophila.

The present research was conducted to prepare efficient G‐SPIONs by co‐precipitation to remove Edwardsiella tarda and Aeromonas hydrophila from the aqueous solution. The synthesized G‐SPIONs were characterized by UV–Vis spectrophotometer, DLS, FEG‐TEM, FT‐IR, XRD, and VSM analysis. The results showed that the synthesized G‐SPIONs had super‐paramagnetic properties (58.31 emu/g) and spherical shape (16 ± 3 nm). The antibacterial activity was assessed in sterilized distilled water at different G‐SPIONs concentrations viz. 0, 1.5, 3, 6, 12, 24, 48, 120, and 240 mg/L against E. tarda and A. hydrophila with various bacterial loads viz. 1 × 103, 1 × 104, 1 × 105, 1 × 106, and 1 × 107 CFU/ml at different time intervals 15, 30, 45, and 60 min. At a lower bacterial load of E. tarda and A. hydrophila 1 × 103–1 × 104 CFU/ml, 100% bacterial load was removed by 15 min exposure with NPs concentration 6–48 mg/L and 1.5–6 mg/L, respectively. Cent percent bacterial removal was observed in both the bacterial species even at higher bacterial load (1 × 105–1 × 107 CFU/ml) by increasing exposure time (15–60 min) and nanoparticle concentration as well (24–240 mg/L). At an initial bacterial load of E. tarda and A. hydrophila (1 × 103–1 × 107 CFU/ml), the EC50 ranged between 0.01–6.51 mg/L and 0.02–3.84 mg/L, respectively, after 15–60 min exposure. Thus, it is concluded that the antibacterial effect of G‐SPIONs depends on concentration and exposure time. Hence, G‐SPIONs can be used as an antibacterial/biocidal agent to treat Edwardsiellosis and Aeromonosis disease in aquaculture. Highlights The glucose‐conjugated super‐paramagnetic iron oxide nanoparticles (G‐SPIONs) synthesized by rapid and high yield co‐precipitation method shows bacterial removal efficiency against Edwardsiella tarda and Aeromonas hydrophila The bacterial removal efficiency of G‐SPIONs depends on concentration and exposure time to both the bacterial species The 100% bacterial removal efficiency can be achieved even at the highest bacterial load (1 × 107 CFU/ml) against E. tarda and A. hydrophila after 45 and 30 min exposure Due to the high bacterial removal efficiency of G‐SPIONs against E. tarda and A. hydrophila, it can be used for the treatment of Edwardsiellosis and Aeromonosis in fish
