Objectives Carbapenem-hydrolysing class D β-lactamases of the OXA-48 type are
increasingly reported from Enterobacteriaceae. β-Lactamase OXA-48 hydrolyses penicillins …

Abstract OXA-48-type carbapenem-hydrolysing class D β-lactamases are increasingly
reported in enterobacterial species. To date, six OXA-48-like variants have been identified …

ABSTRACT Two bla OXA-48-like-positive isolates (Klebsiella pneumoniae and Enterobacter
cloacae) were recovered in Argentina in 2008 as part of a large-scale survey focused on …

The epidemiology of carbapenemases worldwide is showing that OXA-48 variants are
becoming the predominant carbapenemase type in Enterobacteriaceae in many countries …

Three enterobacterial isolates (two Klebsiella pneumoniae and one Escherichia coli) were
recovered from three patients transferred from India to France in 2011. All three isolates …

ABSTRACT OXA-48-type β-lactamases are now routinely encountered in bacterial infections
caused by carbapenem-resistant Enterobacterales. These enzymes are of high and growing …

Pseudomonas aeruginosa isolates 871 and 873 were isolated at Hacettepe University
Hospital in Ankara and were highly resistant to ceftazidime (MIC, 128 μg/ml). Each produced …

The carbapenem-hydrolyzing class D β-lactamases OXA-23 and OXA-24/40 have emerged
worldwide as causative agents for β-lactam antibiotic resistance in Acinetobacter species …

OXA-163 and OXA-48 are closely related class D β-lactamases that exhibit different
substrate profiles. OXA-163 hydrolyzes oxyimino-cephalosporins, particularly ceftazidime …

Pseudomonas aeruginosa clinical isolate PA35 is resistant to amino-and ureido-penicillins,
has intermediate susceptibility to cefsulodin, cefepime and aztreonam, and is susceptible to …
