Abstract

Vibrio parahaemolyticus (V. parahaemolyticus) has been recognized as a significant food-borne pathogen around the
world. In this study, we investigated the prevalence and antimicrobial resistance of V. parahaemolyticus isolated from
raw fishes. A total of 64 samples of raw fishes purchased from a traditional seafood market in Seoul, Korea. were
examined for the presence of V. parahaemolyticus using intestines, gills, and fins. Twenty five grams of all samples
were enriched in 225ml of alkaline peptone water at 37℃ for 24h and then streaked onto thiosulfate citrate bile sucrose
agar. Suspected colonies were inoculated into triple sugar iron agar for biochemical screening test and were finally
confirmed with API 20NE strip. Antimicrobial resistance tests were performed with disc diffusion method in accordance
with National Committee for Clinical Laboratory Standard. Thirty three V. parahaemolyticus strains were isolated from
raw fishes among 33 out of 64 (51.6%). Among 33 isolates, 16 isolates (48.5%) were resistant to ampicillin, 7 isolates
(21.2%) were resistant to amikacin, and all isolates were not resist to other antibiotics such as amoxicillin & clavulanic
acid, sulfamethoxazole & trimethopenem, ciprofloxacin, cefotaxime and cefepime. Although the prevalence of V. parahaemolyticus was high in raw fishes compared to other studies, antimicrobial resistance rate of the isolates was relatively low. These results could be useful information for risk assessment of V. parahaemolyticus in raw fishes.
