To reduce the outbreaks caused by the major pathogenic Vibrio species, V. parahaemolyticus, V. vulnificus, and V. cholerae, the distribution, antibiotic resistance, and virulence of these Vibrio strains were monitored in shellfish and seawater along the Korean coast. Among the Vibrio strains, V. parahaemolyticus was the most abundant species; during summer, this strain showed a substantial increase that correlated with the water temperature. Although >99.0% of the Vibrio species isolates were sensitive to seven antimicrobials recommended by the Center for Disease Control and Prevention for the treatment of Vibrio infections, multiple-antibiotic resistance to at least three antimicrobials was found in 14.3% to 50.0% of each Vibrio species. Among V. parahaemolyticus isolates, 14.3% were positive for the trh gene, whereas only 1% was positive for the tdh gene. These results should aid in implementing proper precautions to avoid potential human health risks associated with exposure to pathogenic Vibrio species.
为了减少由主要致病性弧菌物种（副溶血性弧菌、创伤弧菌和霍乱弧菌）引起的暴发，在韩国沿海的贝类和海水中监测了这些弧菌菌株的分布、抗生素耐药性和毒力。在弧菌菌株中，副溶血性弧菌是最丰富的物种；在夏季，该菌株的数量显著增加，与水温相关。尽管 >99.0%的弧菌分离株对疾病控制与预防中心推荐用于治疗弧菌感染的七种抗生素敏感，但在 14.3%至 50.0%的每种弧菌分离株中发现了至少三种抗生素的多重耐药性。在副溶血性弧菌分离株中，14.3%的 trh 基因呈阳性，而 tdh 基因呈阳性的仅为 1%。这些结果有助于实施适当的预防措施，以避免与接触致病性弧菌物种相关的潜在人类健康风险。
