Surveillance of Vibrio spp in Penaeus monodon collected from shrimp pond of Satkhira, Bangladesh

Abstract

Vibrio is the most common genera associated with crustaceans and often causing significant economic losses. Many Vibrio species are pathogenic to human and have been implicated in food borne diseases. The present study was conducted to identify Vibrio spp. from the tiger shrimp (Penaeus monodon) of shrimp pond at Satkhira, Bangladesh. A total number of 33 Vibrio species isolates were identified from 20 shrimp samples through a series of morphological, physiological and biochemical tests. The work reports the prevalence of Vibrio spp. in the pond environments and the existence of three Vibrio species such as V. alginolyticus, V. parahaemolyticus and V. harveyi were identified. In the study of antibiogram, all isolates were shown 100% sensitive to streptomycin, ciprofloxacin and chloramphenicol. Maximum 41% isolates were shown resistant to co-trimethaxozole whereas 30% and 24% resistant to azithromycin and novobiocin respectively.
