| Abstract: | Enzymatic profiles were determined by the API ZYM system for 15 strains of non 01 Vibrio cholerae, 4 strains of V. metschnikovii, 9 strains of V. anguillarum, 6 strains of Plesiomonas shigelloides and 115 strains motile Aeromonas sp. All of the tested strains produced alkaline phosphatase, leucine aminopeptidase and did not possess alpha-fucosidase and alpha-mannosidase. Some differences in enzymatic activities among the tested Vibrionaceae strains were noted. The strains of non 01 V. cholerae, V. metschnikovii, V. anguillarum and P. shigelloides did not produce trypsin, whereas all of the tested Vibrio sp. strains appeared to be positive for this enzyme. Only the strains of P. shigelloides produced BI-Phospho-hydrolase. The lack of acid phosphatase activity was observed among the strains of V. anguillarum. |
