Vibrio parahaemolyticus was isolated from cultivated oysters (97 strains), the fish hamachi (43 strains), and miscellaneous fishes (171 strains), including mackerel and horse-macherel. It was examined for sensitivity to 6 antibiotics and 7 sulfa drugs by the Showa disc method.
More than 55.8% of the strains of each group showed sensitivity-to oleandomycin. Sensitivity (+++) was exhibited by no strains of fish origin. Then 0-5.3% of the strains of each group were sensitive to gentamycin. To chloramphenicol were sensitive (+++) 39.2% of the strains of oyster origin and 45.6% of the strains of miscellaneous fish origin. Sensitivityto sulfa drugs was manifested by 100%, 94.9%, and 88.5% of the strains of hamachi, miscellaneous fish, and oyster origin, respectively.
