OXA-48-like carbapenemases: the phantom menace.
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, with OXA-48 being the most widespread. They differ by a few amino acid substitutions or deletions (one to five amino acids). The enzymes hydrolyse penicillins at a high level and carbapenems at a low level, sparing broad-spectrum c...
متن کاملCharacterization of Enterobacteriaceae producing OXA-48-like carbapenemases in the UK.
OBJECTIVES To characterize UK clinical isolates of Enterobacteriaceae producing OXA-48-like carbapenemases and to compare their resistance plasmids. METHODS Twenty-six enterobacteria producing OXA-48-like enzymes were studied. These were from 22 diverse hospitals in the UK. Isolates of Escherichia coli and Klebsiella pneumoniae were assigned to clonal lineages by multilocus sequence typing. C...

متن کاملEvaluation of the K-SeT R.E.S.I.S.T. immunochromatographic assay for the rapid detection of KPC and OXA-48-like carbapenemases.
Sir, The worldwide emergence of carbapenemases is a major health issue leaving clinicians with few treatment options. Implementation of infection prevention and control (IPC) procedures relies on early detection of carbapenemase producers and distinction from other carbapenem resistance mechanisms. Various carbapenem hydrolysis methods allow detection of carbapenemase activity but do not differ...
