چکیده

We describe a large hospital outbreak (93 bloodstream infections) of colistin-resistant Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae isolates which was mirrored by increased colistin consumption. The outbreak was mostly traced to the clonal expansion of an mgrB deletion mutant of an ST512 strain that produced KPC-3.

From January 2014 to December 2014, 972 consecutive non-replicate carbapenemase-producing Enterobacteriaceae isolates from colonised or infected patients were collected at the Associated French National Reference Centre as part of the French national survey on antimicrobial resistance. It included 577 Klebsiella spp. (59%), 236 Escherichia coli (24%), 108 Enterobacter spp. (11%), 50 Citrobacter...

Clonal replacement of epidemic KPC-producing Klebsiella pneumoniae in a hospital in China

BACKGROUND Klebsiella pneumoniae is a frequent nosocomial pathogen causing difficult-to-treat infections worldwide. The prevalence of Klebsiella pneumoniae carbapenemase (KPC)-producing Klebsiella pneumoniae (KPC-KP) is increasing in China. The aim of this study was to investigate the molecular epidemiology of KPC-KP in a nosocomial outbreak. METHODS Fifty-four KPC-KP isolates were consecutiv...

Using aGalleria mellonellaanimal model, we compared the virulence of two sequence type 258 (ST258) KPC-producingKlebsiella pneumoniaestrains, which were representative of the two clades of this clonal lineage, with that of isogenic colistin-resistantmgrBmutants. With both strains, themgrBmutants did not exhibit modification in virulence. In theG. mellonellamodel, the clade 1 strain (capsular ty...
