These isolates were selected to capture a diversity of capsular types harbored by the main diverse K. pneumoniae lineages from different clonal groups (CG) that had been involved in human clinical infections and in the expansion of extended-spectrum β-lactamases (mainly, CTX-M-15 and SHV-12) and/or carbapenemases (mainly, KPC-type, OXA-48, VIM, and NDM) (Table 1). Here, CYP27A1 is linked to infection.
