KPC-producing Klebsiella pneumoniae, finally targeting Turkey

Labarca, Jaime ; Poirel, Laurent ; Özdamar, M. ; Turkoglü, S. ; Hakko, E. ; Nordmann, Patrice

In: New Microbes and New Infections, 2014, vol. 2, no. 2, p. 50–51

We report here the first identification of the worldwide spread of Klebsiella pneumoniae carbapenemase-2-producing and carbapenem-resistant K. pneumoniae clone ST258 in Turkey, a country where the distantly-related carbapenemase OXA-48 is known to be endemic. Worryingly, this isolate was also resistant to colistin, now considered to be the last-resort antibiotic for carbapenem-resistant isolates.

The carbapenemase threat in the animal world : the wrong culprit

Poirel, Laurent ; Stephan, Roger ; Perreten, Vincent ; Nordmann, Patrice

In: Journal of Antimicrobial Chemotherapy, 2014, vol. 69, no. 7, p. 2007-2008

We read with great interest two recent publications dealing with the same topic, i.e. the public health risk related to the occurrence of acquired carbapenemase-producing Gram-negative species in the animal world and the environment.1,2 Woodford et al.1 highlight the series of reports of carbapenemases found either in bacteria isolated from non-human sources or in Salmonella enterica subsp....

Carbapenemase-producing Enterobacteriaceae: Overview of a major public health challenge = Entérobactéries et carbapénémases : bilan et enjeux d’un problème de santé publique majeur

Nordmann, Patrice

In: Médecine et Maladies Infectieuses, 2014, vol. 44, no. 2, p. 51–56

Bacterial resistance to antibiotics has become a major source of concern for public health. Enterobacteriaceae are among the most common human pathogens, causing community-acquired as well as hospital-acquired infections. Carbapenem-resistant Enterobacteriaceae have been increasingly reported worldwide since their first identification more than 20 years ago. Three main classes of carbapenemases...

CarbAcineto NP test for rapid detection of carbapenemase-producers in Acinetobacter spp.

Dortet, Laurent ; Poirel, Laurent ; Errera, Caroline ; Nordmann, Patrice

In: Journal of Clinical Microbiology, 2014, p. JCM.00594–14

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...

Rapid detection of carbapenemase-producing Enterobacteriaceae from blood cultures

Dortet, Laurent ; Bréchard, Ludivine ; Poirel, Laurent ; Nordmann, Patrice

In: Clinical Microbiology and Infection, 2013, p. -

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...

High rate of faecal carriage of extended-spectrum β-lactamase and OXA-48 carbapenemase-producing Enterobacteriaceae at a University hospital in Morocco

Girlich, D. ; Bouihat, N. ; Poirel, L. ; Benouda, A. ; Nordmann, Patrice

In: Clinical Microbiology and Infection, 2013, p. -

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...

Enhanced tumour growth and impaired cellular antitumoural defence in hepatic colorectal carcinoma metastasis in rats after laparoscopy compared to open surgery

Inderbitzin, D. Th. ; Marti, G. R. ; Eichenberger, S. ; Hoogewoud, H.-M. ; Kraehenbuehl, L.

In: Annals of Surgical Oncology, 2008, vol. 15, no. 4, p. p

Background This study aims to assess postoperative hepatic growth of colorectal adenocarcinoma metastasis and peritumoural macrophage counts after laparoscopy in an experimental animal model. Methods Thirty male syngenic WAG/Rij rats were randomised into two surgical groups: laparoscopy (LS; n = 15) using CO₂ at 12 mmHg and laparotomy (LT; n = 15; negative control) during an...

A simple deep breathing test reveals altered cerebral autoregulation in type 2 diabetic patients

Brown, Clive M. ; Marthol, H. ; Zikeli, U. ; Ziegler, D. ; Hilz, M. J.

In: Diabetologia, 2008, vol. 51, no. 5, p. 756-761

Aims/hypothesis Patients with diabetes mellitus have an increased risk of stroke and other cerebrovascular complications. The purpose of this study was to evaluate the autoregulation of cerebral blood flow in diabetic patients using a simple method that could easily be applied to the clinical routine screening of diabetic patients.Methods We studied ten patients with type 2 diabetes mellitus and...
