Isolation and identification of Vibrio cholerae and Vibrio parahaemolyticus from prawn (Penaeus monodon) seafood: Preservation strategies

Abstract

Bacterial diseases are one of the major problems which affects the production, development and expansion of aqua culture. Vibrio sp. are widespread in marine and estuarine environments. The several pathogenic species are commonly associated with outbreaks of Vibrio species and it is mainly associated with food poisonings. In this research, the occurrence of Vibrio sp. was studied by the isolation and it is confirmed by the biochemical methods. The growth rate was studied by changing the different operating parameters. Isolation studies were done by using enrichment and selective plating methods. The different biochemical test was carried out and inferred that the isolated organisms were Vibrio choleraee and Vibrio parahaemolyticus. The antibiotic study was also performed to find out the resistant and sensitivity of the Vibrio species. From the results, it was observed that this can be able to correlate the growth of vibrio species to a limited condition and other environmental parameters for which it will be able to find the remedial measures to prevent the growth and spreading of the diseases. Also the different preservation method was carried out to suppress the growth rate of Vibrio sp.
