ABSTRACT
Vibrio parahaemolyticus is a major gastroenteritis-causing pathogen in Korea. Recent studies have reported that heavy metal and antimicrobial resistance in bacteria are related. In this study, we investigated heavy metal and antimicrobial resistance in wild strains of V. parahaemolyticus. First, we isolated and characterized 38 V. parahaemolyticus strains (toxR-positive) from shellfish collected from the West Sea of Korea between May and November 2018. Antibiotic and heavy metal resistance in the 38 strains were tested by disk diffusion assay and broth dilution assay, respectively. Then, we selected seven strains that showed resistance to cobalt (Co2+) and copper (Cu2+), to examine the relationship between heavy metal resistance and antimicrobial resistance. After heavy metal (Co2+ and Cu2+) pretreatment, the seven strains exhibited increased resistance to kanamycin, streptomycin, tetracycline, and gentamycin. Likewise, antimicrobial pretreatment resulted in increased heavy metal tolerance.
