This study explores the genetic basis of antimicrobial resistance and virulence in Klebsiella pneumoniae isolated from different animal species in Germany, including the identification of a hypervirulent strain.
Klebsiella (K.) pneumoniae is an important pathogen in humans and animals, yet data on its occurrence in animals in Germany are limited. This study aimed to investigate the antimicrobial resistance (AMR) profiles, AMR genes, and virulence traits of K. pneumoniae isolates from various animals. A total of 59 isolates collected in 2023 from dogs, cats, horses, cattle, and chickens across 11 German federal states were analysed using whole-genome sequencing and antibiotic susceptibility testing.
