OCCURRENCE OF Vibrio cholerae IN SHRIMP CULTURE ENVIRONMENTS OF KERALA, INDIA
Journal Title: Indian Journal of Scientific Research - Year 2015, Vol 5, Issue 2
Abstract
The present study was conducted in order to monitor the presence of Vibrio cholerae in extensive and modified extensive shrimp culture systems. In extensive system, V. cholerae count ranged from 180 to 380 cfu ml-1 and 187 to 668 ml-1 in modified extensive system. In the present study sediment registered highest Vibrio load in both systems (1725-2708 cfu g-1 and 2019 to 5699 cfu g-1). In extensive system, percentage distribution of V. cholerae in water was 6.5, 7.2 and 16.6%, respectively, for premonsoon, monsoon and postmonsoon. In, modified extensive system, in water, percentage distribution of V. cholerae was the highest during postmonsoon (11.3%) and the lowest during monsoon (8.3%). Premonsoon registered 10.3% and annual mean, 10.3%. In the present study V. cholerae loads were found to increase with advancement of culture operation in both extensive and modified extensive culture systems. The presence of V. cholerae serve as an indicator of public health safety of water and food destined for human consumption. So an assessment of V. cholerae was done in order to evaluate the health status of the ponds.
