Title : Antibiotic resistance of Vibrio parahaemolyticus isolated from cultured groupers (Epinephelus spp) in Phu Yen, Vi
Abstract:
Phu Yen is a coastal province in the region Central, Vietnam, where there is marine fish farming cages and ponds are quite developed. Here, grouper (Epinephelus spp) is one of the subject of rearing. However, the disease and its harmful effects are still a big obstacle to raising this animal locally Scattered or mass deaths often occur and cause damage to farmers. Vibrio parahaemolyticus is a major cause of foodborne infections and is responsible for significant losses in marine aquaculture in worldwide. However, the prevalence and antibiotic resistance of V. parahaemolyticus in cultured groupers in Vietnam, are still poorly understood. In the present study, 23 V. parahaemolyticus isolates were recovered from 102 samples from 10 ship farms in Phu Yen province. Most of isolates exhibited resistance to tetracycline (95.65%), erythromycin (91.3%), ampicillin (78.26%) and amoxicillin (65.23%). Conversely, enrofloxacin, ofloxacin and chloramphenicol were the most effective drugs for the treatment of V. parahaemolyticus with more than 90% efficiency. These results indicate the need for prudent use of antibiotics on fish farm in Vietnam and to develop effective treatment strategies for V. parahaemolyticus including vaccine development based on virulence genes in the near future.
