Abstract
We report the prevalence and characterization of ,em>Vibrio</em> spp. isolated from marketed Yesso scallop (<em>Patinopecten yessoensis</em>) in Korea. A total of 30 isolates including, <em>V. parahaemolyticus</em> (n = 2),
<em>V. alginolyticus</em> (n = 9), <em>V. fluvialis</em> (n = 7), <em>V. diabolicus</em> (n = 7), <em>V. anguillarum</em> (n = 4) and <em>V. aestuarianus</em> (n = 1) were isolated and identified. The phenotypic pathogenicity tests demonstrated that, 18 (60%), 21 (70%), 18 (60%), 7 (23%), 22 (73%), 21 (70%), 9 (30%), and 11 (33%) of the isolates were positive for DNase, protease, gelatinase, lipase, phospho-lipase, amylase, slime production, and haemolysis, respectively. PCR assays revealed the prevalence of <em>toxR, tlh, VAC, vfh, hupO</em>, and <em>VPI</em> genes among the isolates with varying combinations. A close genetic affinity among <em>V. alginolyticus</em> and <em>V. diabolicus</em> strains was observed. Also the virulence genes specific to one Vibrio species were detected among other species as well. In addition, 29/30 (97%) isolates were multidrug resistant, while higher resistance rates were shown for ampicillin, colistin, vancomycin, and cephalothin. The results imply that the scallops in Korean markets harbor <em>Vibrio</em> spp., which are potentially virulent and multidrug resistant, thus their public health implications should not be underrated.
