Abstract

A simple experiment was carried out to examlne the effect of varlous physicochemical conditions on toxigenicity and toxin genes of Vibrio cholerae 01 lsolated from an artificial aquatic environment. All isolated strains, tested by tissue culture assay, DNA-DNA hybridization and ELISA, were cytotoxic to Vero cells, did not lose their toxin genes and continued to produce cholera toxin. These results are consistent with the hypothesis that V. cholerae can survive in the environment without losing potential pathogenicity.
