The dissemination of carbapenemase-producing bacteria worldwide is an important source of concern because carbapenemase producers are multidrug resistant (Nordmann and Poirel, 2014). National guidelines increasingly recommend a systematic screening of at least carbapenemase-producing Enterobacteriaceae (CPE) and glycopeptide-resistant enterococci (GRE) in patients admitted to hospitals who have...

From June to September 2012, 500 urine samples were recovered from patients with urinary tract infections (UTI) due to Gram-negative bacilli (≥10⁴ leukocytes/ml and ≥10⁵ Gram-negative isolates/ml) who visited the University hospital Bicêtre (France). They were challenged with extended-spectrum-β-lactamase (ESBL)-producing Enterobacteriaceae (ESBL-E) using the rapid diagnostic ESBL NDP...

The emergence of one of the most recently described carbapenemases, namely, the New Delhi metallo-lactamase (NDM-1), constitutes a critical and growingly important medical issue. This resistance trait compromises the efficacy of almost all lactams (except aztreonam), including the last resort carbapenems. Therapeutical options may remain limited mostly to colistin, tigecycline, and fosfomycin....

Multidrug-resistant Acinetobacter baumannii isolates, and particularly carbapenemase-producing isolates, are increasingly reported worldwide. The biochemically-based Carba NP test, extensively validated for detection of carbapenemase producers among Enterobacteriaceae and Pseudomonas spp., has been modified for the detection of carbapenemase production in Acinetobacter spp. A collection of 151...

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...

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 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...
