OXA-163-Producing Klebsiella pneumoniae in Cairo, Egypt, in 2009 and 2010

2012

ABSTRACT Two genetically unrelated OXA-163-carrying Klebsiella pneumoniae strains were identified from two infection cases in June 2009 and May 2010 in Cairo, Egypt. OXA-163-producing Enterobacteriaceae had been previously reported in Argentina only. Both patients had no history of travel abroad. The emergence of this newly recognized OXA-48-related β-lactamase able to hydrolyze cephalosporins and carbapenems is especially worrying in a geographic area where OXA-48 is endemic and effective surveillance for antibiotic resistance is largely unaffordable.

NDM-1 and OXA-163 producing Klebsiella pneumoniae isolates in Cairo, Egypt, 2012

2013

Here we describe carbapenem resistance determinants in two Klebsiella pneumoniae isolates recovered from two hospitalised patients in the same intensive care unit of a cancer hospital in Cairo, Egypt. PCR and sequencing were used to detect and characterise β-lactamase genes. Clonal relationships between the isolates were analysed by pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST). The first K. pneumoniae isolate carried the blaNDM-1 gene and the second isolate carried the blaOXA-163 gene. Both isolates co-expressed the extended-spectrum β-lactamase CTX-M-15. The two isolates belonged to different sequence types (STs), ST11 and ST16, respectively. No history of …
