Comparative genomic analysis of the novel strain <i>Vibrio cidicii</i> VC01, isolated from China

<i>Vibrio cidicii</i> strains are opportunistic pathogens causing bacteremia in humans and can be multidrug-resistant. Since few studies report on <i>Vibrio cidicii</i> strains, there is a lack of knowledge of the genetic diversity, presence of antimicrobial resistance genes, and virulence factors in <i>V. cidicii</i> strains. This study revealed the genomic features, phylogeny, and diversity of <i>V. cidicii</i> strains, highlighting five O-antigen biosynthesis gene cluster genotypes in <i>V. cidicii</i> strains and a Tn7-like transposon carrying a type Ⅰ restriction-modification in VC01. These findings provide new insights into the genetic diversity and antimicrobial potential of <i>V. cidicii</i> strains.
