Characterize a NDM-1 producing K. pneumoniae isolate recovered from a patient hospitalized in Guadeloupe, French West Indies, after its transfer from CubaMethodsAntibiotic susceptibilities were determined by the disk diffusion method, and E-test. Carbapenemase production was assessed using the Carba NP test. Antibiotic resistance determinants and their surrounding structures were...

The epidemiology of carbapenemases worldwide is showing that OXA-48 variants are becoming the predominant carbapenemase type in Enterobacteriaceae in many countries. However, not all OXA-48 variants possess significant activity toward carbapenems (e.g., OXA-163). Two Serratia marcescens isolates with resistance either to carbapenems or to extended-spectrum cephalosporins were successively...

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....

We rapidly identified extended-spectrum β-lactamase (ESBL) producers prospectively among 245 gram-negative bacilli–positive cultured blood specimens using the Rapid ESBL Nordmann/Dortet/Poirel test and direct bacterial identification using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. This combination identified ESBL-producing Enterobacteriaceae within 30 min...

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...

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 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...
