Genomic Characterization of Klebsiella quasipneumoniae from Clinical Specimens in Singapore.
Ontology highlight
ABSTRACT: A total of 1,281 specimens from 1,024 patients were screened. Phylogenetic analysis classified 44 of these isolates as Klebsiella quasipneumoniae subsp. similipneumoniae (44/1,281 [3.4%]) and the remaining three as K. quasipneumoniae subsp. quasipneumoniae. The most common specimen source was urine (21/47 [44.7%]) followed by blood (14/47 [29.8%]). K. quasipneumoniae isolates were nonclonal. Carbapenemase-encoding genes (blaNDM and blaOXA-181) were detected in only two isolates (2/47 [4.3%]). K. quasipneumoniae appears to cause a spectrum of infections similar to those of K. pneumoniae, although higher rates of susceptibility to many commonly tested antimicrobials and low prevalence of virulence genes were demonstrated.
