Due to the emergence of antibiotic-resistant pathogens, probiotics in aquaculture are used for the prevention of infectious microbial diseases and substitute for antibiotics and chemotherapeutics. In this study, we evaluated the effect of probiotic Bacillus spp. isolated from African nightcrawler (Eudrilus eugeniae) on the growth, feed utilization, and disease resistance of Nile tilapia (Oreochromis niloticus). Four probiotic strains of Bacillus spp. (ANSCI9, BFAR9, RM3, and RM10) were individually incorporated in the commercial diet (control) at 10 8 CFU g -1 of feed. The experimental fish were fed at 5% of their body weight for 30 days, and subjected to a 14-day Aeromonas hydrophila challenge test afterward. The results showed the probiotic-treated groups have higher (P<0.05) average body weight (ABW) (4.51 ± 0.34 g) than the control (3.89 ± 0.17 g). The BFAR9 (2.73 ± 0.26 g) and RM10 (3.15 ± 0.30 g) showed higher (P<0.05) absolute growth (AG) than the control (2.20 ± 0.16 g). Furthermore, RM10 had higher (P<0.05) specific growth rate (SGR) (1.60 ± 0.10 % day -1 ) and relative growth rate (RGR) (181.39 ± 18.16 %) than the control (SGR=1.29 ± 0.07 % day -1 ; RGR=129.84 ± 9.77 %). Consequently, RM10 had significantly lower (P<0.05) feed conversion ratio (FCR) (1.99 ± 0.13) than the control (2.60 ± 0.16). The challenge test revealed that the probiotic-treated groups have higher (P<0.05) survival (81.25 ± 9.57 %) than the control (55.00 ± 19.15 %). These results revealed that the probiotic Bacillus spp. isolated from E. eugeniae improved the growth, feed utilization, and the disease resistance of Nile tilapia.

“…Bacillus is an extremely diverse group of bacteria that includes both the causative agent of anthrax ( Bacillus anthracis ) and several species that synthesize important antibiotics. In aquaculture, most Bacillus bacteria reported have been probiotic, including Bacillus amyloliquefaciens (Reda & Selim, ; Selim & Reda, ), Bacillus subtilis (Aly, Ahmed, Ghareeb, & Mohamed, ) and Bacillus pumilus (Aly, Mohamed, & John, ; Hong et al, ; Wang et al, ). The use of probiotic bacteria is regarded as a promising strategy and their use in aquaculture has been widely accepted, as is evident from the number of research studies published over the last ten years (Balcázar et al, ; Merrifield et al, ; Swapnap et al, ; Wang, Li, & Lin, ).…”

The giant river prawn, Macrobrachium rosenbergii, is an economically important freshwater prawn. The cultivation of zoea larvae is crucial for the success of the M. rosenbergii industry. In this study, we surveyed the microbial community diversity and structure associated with M. rosenbergii zoeae at different stages of larval development. Samples of zoea larvae from different developmental stages were collected and subjected to high‐throughput DNA sequencing. Firmicutes, Proteobacteria, Bacteroidetes and Actinobacteria were the dominant phyla in all six sample groups. At the genus level, the relative abundance of Bacillus decreased, and that of Enterobacter increased with the growth of the zoeae. This may have been related to the intestinal development of the zoea larvae. The microbial diversity of M. rosenbergii zoea larvae decreased significantly with development. The beta diversity analysis showed that the closer the developmental stage of M. rosenbergii, the more similar the structure of the associated bacterial communities.

Sixty days feeding trial was carried out to investigate the supplemental effects of dietary phytobiotic mixture composed of Spirulina platensis powder (SP) and Garlic powder (GP) on the growth performance, intestinal morphometry, and immune responses of Nile tilapia Oreochromis niloticus. A total of 240 cultured O. niloticus (41.4 ± 0.09 g) were randomly divided into four experimental groups (three replicate/group), fed on basal diets contain 0% (control), 1% (SP), 0.5% (GP), or a combination of both (SP + GP). Fish group fed on phytobiotic mixture showed significant improvements in its feed intake, live weight gain, specific growth rate, feed conversion ratio and protein efficiency ratio (p<0.05), associated with a healthy gut, compared to non-supplemented control. Dietary supplementation of phytobiotics appeared to stimulate the humoral and cellular innate immunity. Fish group that were fed on phytobiotic mixture revealed up-regulation in some immune related genes; TNF-α and liver hepcidin as well as it exhibited the least cumulative mortality % upon A. hydrophila infection. So we can conclude that dietary supplementation of garlic and Spirulina have been improved the growth performance, gut health, immune status and disease resistance in Nile tilapia.
