چکیده انگلیسی
We performed a single-month snapshot study of the population diversity of multidrug resistant (MDR) Klebsiella pneumoniae isolates producing carbapenemases and/or extended-spectrum β-lactamases from four major hospitals in Brazil. Isolates produced diverse ESBL (CTX-M-2, -8, -15, SHV-2), KPC-2 or both (CTX-M-2 and KPC-2), linked to specific genetic backgrounds and plasmids from a few families (IncR, IncFIIk, IncL/M) that were shared among clonal lineages within and between hospitals. A high clonal diversity was identified, among isolates from the same ST (ST11, ST15, ST101 or ST340). Diverse capsular types (n=13 K-types) were identified, most of which linked to specific ST (ST11 and K27 or K64, ST101 and K17, ST340 and KL151, ST15 and K24 or ST17 and KL112). Isolates shared a common set of virulence genes (ureA, fimH, uge, wabG, mrkD, entB) and occasionally ybtS (42%) and kfuBC (18%). Our data suggest intra- and inter-hospital spread of common genetic structures and international MDR K. pneumoniae clones.
