Abstract / Zusammenfassung

Vibrio spp. are natural inhabitants of the aquatic environment. Among the members of the genus, twelve species have been reported to be pathogenic to humans and can cause foodborne infections. The aim of the recent study was to investigate the prevalence and the antimicrobial resistance patterns of Vibrio spp. isolated from retail shrimps in Hanoi, Vietnam. A total of 202 shrimp samples were collected from retail markets located in ten urban districts of Hanoi. Among those, 201 (99.5%) samples were positive for Vibrio spp. The most common species detected was V. parahaemolyticus (95.5%), followed by V. alginolyticus (56.4%), V. cholerae (2%) and V. vulnificus (1.5%). Multiple Vibrio spp. were found in 114 (56.4%) samples. In total, 195 V. parahaemolyticus isolates, four V. cholerae isolates and three V. vulnificus isolates, which are Vibrio species associated with foodborne infections, were tested for resistance to eight antimicrobial drugs using the disc diffusion method. V. parahaemolyticus isolates showed a high rate of resistance against ampicillin (87.2%), while a moderate rate was observed for sulfamethoxazole/trimethoprim (18.5%) and intermediate resistance towards tetracycline (24.6%). Low resistance rates (0.5%) were recorded against both ciprofloxacin and cephalothin. Only one V. cholera isolate with resistance to ampicillin and two V. cholerae isolates to sulfamethoxazole/trimethoprim were found. All of the V. vulnificus isolates (n=3) were susceptible to the eight antimicrobial agents tested. Among the three Vibrio species, multi-resistance was found only in V. parahaemolyticus (16.9%). The result of this study indicates the high prevalence of Vibrio spp. in shrimp resistant to likewise ampicillin and sulfamethoxazole/trimethoprim.
