Epidemiological characteristics, virulence genes, and antimicrobial resistance analysis of <i>Vibrio parahaemolyticus</i> in diarrheal cases in Huzhou City from 2021 to 2023.

ABSTRACT: Vibrio parahaemolyticus has emerged as a predominant cause of seafood-related infections globally. Despite this, a comprehensive analysis of its epidemiological traits and antimicrobial resistance patterns in Huzhou City remains lacking. Our study isolated 250 strains of V. parahaemolyticus from a total of 6,404 diarrhea patients sampled across six hospitals in Huzhou from 2021 to 2023. Epidemiological analysis revealed higher infection rates in warmer seasons, with the majority of cases occurring in individuals aged from 25 to 64. No significant gender-based difference was observed in the prevalence of V. parahaemolyticus. Serotype analysis identified O10:K4 as the predominant serotype. 93.20% (233/250) of clinical isolates harbored the tdh gene, while 4.0% (10
