Risk factors for acquisition of colistin-resistant Klebsiella pneumoniae and expansion of a colistin-resistant ST307 epidemic clone in hospitals in Marseille, France, 2014 to 2017.

ABSTRACT: BackgroundFrance is a low prevalence country for colistin resistance. Molecular and epidemiological events contributing to the emergence of resistance to colistin, one of the 'last-resort' antibiotics to treat multidrug-resistant Gram-negative infections, are important to investigate.AimThis retrospective (2014 to 2017) observational study aimed to identify risk factors associated with acquisition of colistin-resistant Klebsiella pneumoniae (CRKP) in hospitals in Marseille, France, and to molecularly characterise clinical isolates.MethodsTo identify risk factors for CRKP, a matched-case-control (1:2) study was performed in two groups of patients with CRKP or colistin-susceptible K. pneumoniae respectively. Whole-genome-sequences (WGS) of CRKP were compared with 6,412 K. pn
