The performance of Etest KPC and MBL strips (bioMérieux) was evaluated as compared to other phenotypic tests for detecting carbapenemases of the KPC-type and metallo-β-lactamases, respectively, on 133 well-characterized enterobacterial isolates. KPC and meropenem-containing MP/MPI Etest had high sensitivity (>92 %) and specificity (>97 %).

A prospective survey was conducted on 862 Enterobacteriaceae with reduced susceptibility to carbapenems. The Carba NP test, UV spectrophotometry and DNA microarray were used for detecting carbapenemase producers, and results compared to PCR and sequencing. The 172 carbapenemase producers were detected using the Carba NP test and UV spectrophotometry whereas DNA microarray failed to detect IMI...

Objectives: Carbapenem-resistant Enterobacteriaceae isolates (n = 1485) were received at the French Associated National Reference Center for Antibiotic Resistance in 2012 and were characterized for their mechanism of resistance to carbapenems.Methods: Carbapenemase production was detected using the biochemical-based Carba NP test, based on the detection of in vitro hydrolysis of imipenem. All...

Comparative evaluation of the recently developed chromogenic culture medium chromID OXA-48 (bioMérieux) with chromID CARBA (bioMérieux) and SUPERCARBA showed that chromID OXA-48 and SUPERCARBA media have the highest sensitivity for detection of OXA-48 producing Enterobacteriaceae (91% and 93%) comparatively to chromID CARBA (21 %). The chromID OXA-48 has the highest specificity, with 100%, as...

The Carba NP test has been evaluated to detect carbapenemase-producing Pseudomonas spp. directly from blood cultures. This rapid and cost-effective test permits an early identification of carbapenemase-producing Pseudomonas spp. directly from blood cultures with excellent sensitivity and specificity. Results may be useful in particular for guiding the first-line therapy and epidemiological...

The impact of carbapenemase production among clinically significant Gram-negative rods is becoming a major medical issue. To date, Acinetobacter baumannii has been considered as a final recipient of carbapenemase genes (imipenemase, Verona metallo-β-lactamase, Guiana extended-spectrum β-lactamase and Klebsiella pneumonia carbapenemase types) from Enterobacteriaceae and ...

The biochemical-based Carba NP test has been evaluated to detect carbapenemase- producing Enterobacteriaceae (n = 193) directly from spiked blood cultures. It was able to rapidly detect KPC (n = 50), IMP (n = 27), VIM (n = 37), NDM (n = 33) and OXA-48-like producers (n = 46) with sensitivity and specificity of 97.9% and 100%, respectively. This cost-effective technique may be implemented in...

Carbapenemase-producing Enterobacteriaceae isolates are being increasingly reported, particularly from countries surrounding the Mediterranean area. We aimed to quantify the prevalence of carbapenemase- and extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae in rectal swabs from hospitalized patients in a University hospital in Morocco, and to compare the performance of three...
