Influence of salinity upon the phenotypic expression of antibiotic resistance in nonhalophilic and halophilic vibrios.

The purpose of the present work is to demonstrate the influence of different NaCI concentrations included in the Mueller Hinton medium, upon the antibiotic susceptibility of 10 non-halophilic and 28 halophilic Vibrio strains. The highest number of resistance aspects were recorded at 1% NaCl concentration for V. cholerae O1/non O1 strains and at 3% for V. parahaemolyticus, V. algynolyticus, V. vulnificus, V. fisheri, V. anguillarum and V. metschnikovii.
