Carbapenems, once considered the last line of defense against of serious infections with Enterobacteriaceae, are threatened with extinction. The increasing isolation of carbapenem-resistant Gram-negative pathogens is forcing practitioners to rely on uncertain alternatives. As little as 5 years ago, reports of carbapenem resistance in Enterobacteriaceae, common causes of both community and healt...

Performances of the Rapidec Carba NP test (bioMérieux) were evaluated for detection of all types of carbapenemases in Enterobacteriaceae, Acinetobacter baumannii, and Pseudomonas aeruginosa. In less than 2 h after sample preparation, it showed a sensitivity and specificity of 96%. This ready-to-use test is well adapted to the daily need for detection of carbapenemase producers in any laboratory...

A commercial multiplex PCR (hyplex SuperBug ID) was tested with a collection of 132 clinical Enterobacteriaceae strains producing different carbapenemases. The sensitivity for the detection of KPC-, VIM-, NDM-, and OXA-48-encoding genes was 100%, whereas two IMP variants were missed.

A study was designed to evaluate the modified Hodge test (MHT), Mastdiscs ID inhibitor combination disks (MDI), Rosco Diagnostica Neo-Sensitabs (RDS), metallo-β-lactamase (MBL) Etest, and in-house multiplex PCR for the detection of well-characterized carbapenemase-producing Enterobacteriaceae. One hundred forty-two nonrepeat clinical isolates of carbapenemase-producing Enterobacteriaceae (inclu...

Introduction: The capacity of resistance to β-lactam among enterobacteriales is notable, mainly into water environment. Herein, many species this family have the ability carrier and produce β-lactamases enzymes, such as extended-spectrum (ESBLs) carbapenemases. However, contrary clinical settings, where distribution resistant bacteria well documented, evidence resis-tant pathogens in domestic s...
