In this study, a survey was conducted in the Jiangxi Province of China, covering a total of 140 CRKP strains collected from 11 hospital laboratories from June 2016 to January 2018. All CRKP isolates were subjected to antimicrobial susceptibility testing, capsular serotypes, virulence gene profiles, multilocus sequence typing, and pulsed-field gel electrophoresis. The differences in the patient characteristics and distributions among the various regions were statistically significant (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009\u2264\u20090.001). Most patients were hospitalized in intensive care units (30.0%) and burn departments (13.6%), with lower respiratory (52.1%) and urinary tract (15.7%) infections being most prevalent. A higher ratio of CRKP isolates were identified in the southern and central regions of Jiangxi than in the other regions.

A total of 39 virulent strains were detected, of which 22 strains were classified by capsule serotyping. Hypervirulent genes were most common in the eastern and central regions of Jiangxi.
