Abstract
The study was conducted to determine the levels of antibiotic resistance and multiple antibiotic resistance of 150 Vibrio spp. isolates from white-leg shrimp (Litopenaeus vannamei) collected from Binh Dien Wholesale Market in Ho Chi Minh City. Ten antibiotics were used to test the resistance of Vibrio ssp. isolates including ampicillin, ciprofloxacin, chloramphenicol, doxycycline, gentamicin, kanamycin, nalidixic acid, streptomycin, tetracycline, and trimethoprim/sulfamethoxazole. Antibiotic susceptibility test results showed that the percentage of Vibrio spp. resistance to the above antibiotics was 92; 12; 0; 0; 3.3; 80; 3.3; 46.7; 3.3 and 18.0%, respectively. The percentage of multiple resistant isolates from two to five tested antibiotics was 88.7%. Especially, none of the isolates were sensitive to all tested antibiotics. The multiple antibiotic resistance (MAR) index value was 0.259 indicating that these isolates were exposed to high-risk sources of contamination where antibiotics were commonly used.
