Abstract

Klebsiella oxytoca complex comprises nine closely related species causing human infections. We curated genomes labeled Klebsiella ( = 14,256) in GenBank and identified 588 belonging to the complex, which were examined for precise species, sequence types, K- and O-antigen types, and virulence and antimicrobial resistance genes. The complex and Klebsiella pneumoniae share many K- and O-antigen types. Of the complex, K. oxytoca and Klebsiella michiganensis appear to carry more virulence genes and be more commonly associated with human infections.
