V. cholerae 01 E1 Tor isolated during Cholera epidemic of 1994 and V cholerae 0139 serotype isolated during 1993 epidemic were subjected to the study of proteases and other enzymes. Out of 26 strains of V. cholerae 01 studied, gelatinase and caseinase activity was seen in 100 and 69.23 percent strains respectively. All strains showed catalase and oxidase activity. Of the other enzymes studied 19.23, 65.38 and 57.69 percent strains were positive for DNAse, lipase and phosphatase respectively. None of the strains showed lecithinase activity. Similar findings were observed in 22 strains of V. cholerae 0139 except all strains were positive for phosphatase activity. Role of enzymes in virulence is suggested.
