dc.description.abstract | Water and post-larvae samples from black tiger (Penaeus monodon) shrimp hatcheries; pond water, pond sediment and shrimp from aquaculture farms were screened for the presence of V cholerae. A V cholerae-duplex PCR method was developed by utilizing V cholerae species specific sodB primers and ctxAB genes specific primers. Incidence of V cholerae was not observed in shrimp hatchery samples but was noticed in aquaculture samples. The incidence of V cholerae was higher in pond water (7.6%) than in pond sediment (5.2%). Shrimp head (3.6%) portion had relatively higher incidence than shrimp muscle (1.6%). All the V cholerae isolates (n=42) belonged to non- 01/non-0139 serogroup, of which 7% of the V cholerae isolates were potentially cholera-toxigenic (ctx positive). All the ctx positive V cholerae (n=3) were isolated from the pond water. Since, cholera toxin (CT) is the major contributing factor for cholera gravis, it is proposed that the mere presence of non-01/non-0139 V cholerae need not be the biohazard criterion in cultured black tiger shrimp but only the presence of ctx carrying non-01/non-0139 V cholerae may be considered as potential public health risk. | en_US |
