Comparative efficacy of pre-moistened sponges and E-swabs for active surveillance of carbapenem-resistant Acinetobacter baumannii carriage.

We evaluated whether skin sampling with E-swabs is an effective alternative to pre-moistened sponges for detecting carbapenem-resistant Acinetobacter baumannii (CRAB) carriage. Skin samples were collected by sponges with enrichment and E-swabs with and without enrichment. We collected 899 samples (from 250 patients); 191 samples were CRAB positive.

Characterization of Enterobacterales growing on selective CPE screening plates with a focus on non-carbapenemase-producing strains.

Unlabelled: Carbapenem-resistant Enterobacterales (CRE) are divided into two distinct groups: carbapenemase-producing (CPE) and non-carbapenemase-producing (non-CPE). The population of non-CPE growing on CPE selective plates during routine screening is usually not reported and is not well defined. This study aimed to characterize non-CPE isolates growing on those plates.

Evaluation of the CARBA PAcE test, a colorimetric imipenem hydrolysis test for rapid detection of carbapenemase activity.

There is an urgent need for accurate and fast diagnostic tests to identify carbapenemase-producing bacteria. Here, we evaluated a colorimetric imipenem hydrolysis test, called the CARBA PAcE test, to detect carbapenemase-producing Gram-negative bacteria (GNB). We tested a collection of 270 GNB isolates with a characterized carbapenemase content.

Carbapenem-resistant carrier detection: a simple and efficient protocol.

Unlabelled: Timely detection of carbapenem-resistant (CRAB) carriers is essential to direct infection control measures. In this work, we aimed to develop a practical protocol to detect CRAB from screening samples. To choose a selective medium that detects CRAB with high sensitivity and specificity, 111 .

Plasmid-encoded VCC-1 β-lactamase in a clinical isolate of .

arbapenemase (VCC-1) is a chromosomal encoded class A carbapenemase thus far reported in environmental isolates. Here, we report the first isolation of a -carrying from a clinical sample in Israel. The isolate was resistant to all β-lactam agents, including carbapenems.
