title: Shrimps survive white spot syndrome virus challenge following treatment with Vibrio bacterin.
abstract: Taking an innovative approach, a vaccination study using five bacterial strains viz. Vibrio campbelli (B60), V. alginolyticus (B73), V. parahaemolyticus-like (B79), V. parahaemolyticus (R8) and V. harveyi (RG203) was conducted in Penaeus monodon against white spot syndrome virus (WSSV) infection, considered as one of the serious pathogens of shrimps. Oral challenge with shrimps infected with WSSV showed a relative percentage survival of 5 and 47% in the P. monodon juveniles vaccinated with V. parahaemolyticus and V. harveyi, respectively. Results showed that there is a possibility of specifically immunising the shrimps against WSSV using bacterin prepared out of Vibrio harveyi isolates taken from shrimps infected with WSSV. Also, there was a level of protection attained by the shrimps due to immunisation with Vibrio strains.
