The current emergence of the carbapenemase OXA-48 among Enterobacteriaceae is related to the spread of a single IncL/M-type plasmid, pOXA-48a. This plasmid harbors the blaOXA-48 gene within a composite transposon, Tn1999, which is inserted into the tir gene, encoding a transfer inhibition protein. We showed that the insertion of Tn1999 into the...

We report the first outbreak of carbapenem-resistant NDM-1-producing Acinetobacter baumannii in Europe, in a French intensive-care unit in January to May 2013. The index patient was transferred from Algeria and led to the infection/colonisation of five additional patients. Concurrently, another imported case from Algeria was identified. The seven isolates were genetically indistinguishable,...

OXA-48 beta-lactamase producers are emerging as an important threat mostly in the Mediterranean area. We report here the molecular epidemiology of a collection of OXA-48 beta-lactamase-positive enterobacterial isolates (n=107) recovered from European and north-African countries between January 2001 and December 2011. This collection included 67 Klebsiella pneumoniae, 24 Escherichia coli and 10...

The spread of carbapenemase-producing Enterobacteriaceae (CPE) is a threat to healthcare delivery, although its extent differs substantially from country to country. In February 2013, national experts from 39 European countries were invited to self-assess the current epidemiological situation of CPE in their country. Information about national management of CPE was also reported. The results...

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...

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...
