Abstract
B. subtilis and S. algae effects in growth, survival and innate immunity were assessed on L. vannamei juveniles. During 60 days, shrimp were reared in three treatments: Bs, fed with 106 CFU of B. subtilis per gram of commercial feed, Sa, fed with 106 CFU of S. algae per gram of commercial feed and Control (without bacterial addition). Then, the animals were subjected to a V. parahaemolyticus challenge. For this purpose, four treatments were established: Control (shrimp not submitted to probiotic treatments), Vibrio (Vibrio challenged shrimp), Vibrio + Bs (Bs challenged shrimp) and Vibrio + Sa (Sa challenged shrimp). Shrimp hemolymph was sampled 45-days after rearing and 24 h post-challenge for quantification of prophenoloxidase (proPO), lipopolysaccharide and β-1,3-glucan-binding protein (LGBP) and hemocyanin (HEM) transcripts by qPCR. Moreover, shrimp final weight and survival were also verified. B. subtilis administration enhanced shrimp growth and improved proPO, LGBP and HEM expression levels before and after challenge. After 60-days of feeding, Sa final weight was higher than the Control, whereas Vibrio + Sa cumulative mortality after 48 h of Vibrio challenge was lower than Vibrio group. These results could be correlated with the proPO and LGBP up regulation in Vibrio + Sa compared to Vibrio group, protecting L. vannamei from the bacterial infection. Together, these results suggest the probiotic potential of B. subtilis e S. algae in the modulation of immune-related genes as a tool to control V. parahaemolyticus infection inside shrimp.
