Antibiotic- and Metal-Resistant Strains of Vibrio parahaemolyticus Isolated from Shrimps

Enteropathogenic strains of Vibrio parahaemolyticus were isolated from shrimps, Penaeus monodon collected from the region of the Deltaic Sundarbans (West Bengal, India). About 63% of the isolated strains were resistant to ampicillin, cephalexin, and kanamycin. However, all these strains were sensitive to nitrofurantoin, nalidixic acid, tetracycline, and norfloxacin. The isolated strains were resistant to Ni2+] (75%), Cu2+ (87%), and Co2+ (37%), but all the strains were resistant against Cd2+, Zn2+, and Pb2+ at 10 mM concentration.
