Genetic diversity, virulence genes, antimicrobial resistance, and biofilm formation of <i>Klebsiella pneumoniae</i> isolated from bovine mastitis milk in South Korea.

ABSTRACT: Klebsiella pneumoniae, a zoonotic agent, is a causative pathogen of bovine mastitis. Despite its clinical relevance in dairy farms, studies on K. pneumoniae in bovine mastitis remain limited. Additionally, studies on K. pneumoniae's genetic diversity and virulence characteristics in South Korea remain limited. Therefore, in this study, we aimed to elucidate the genetic diversity, antimicrobial resistance, virulence genes, and biofilm-forming capacity of 29 K. pneumoniae strains isolated from bovine mastitis milk samples in South Korea between 2017 and 2023. Multilocus sequence typing revealed 23 sequence types, four of which were novel, indicating substantial genetic heterogeneity and the absence of a dominant clonal lineage. Excluding intrinsic resistanc
