Simplified Protocol for Carba NP Test for Enhanced Detection of Carbapenemase Producers Directly from Bacterial Cultures.
نویسندگان
چکیده
We compared carbapenemase detection among 266 Gram-negative bacilli (161 carbapenemase producers) using the Carba NP tests issued by the CLSI (CNPt-CLSI) and a novel protocol (CNPt-direct) designed for carbapenemase detection direct from bacterial cultures (instead of bacterial extracts required by the CLSI tests). The specificities were comparable (100%), but the CNPt-direct was more sensitive (98% versus 84%). The CNPt-direct was easier to perform due to the direct use of colonies and offered a more robust detection of carbapenemase producers.

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

OBJECTIVES The objective of this study was the evaluation of the performance of two commercially available biochemical tests for the rapid detection of carbapenemase-producing Enterobacteriaceae compared with a home-made technique. METHODS A collection of 150 enterobacterial isolates, including 132 isolates with decreased susceptibility to at least one carbapenem molecule, were tested for car...
متن کاملEvaluation of Carba NP Method for Rapid Detection of Pseudomonas aeruginosa Isolates Producing Carbapenemase Enzymes
Background and purpose: Recently, increased resistance to carbapenem antibiotics among Pseudomonas aeruginosa has raised concerns. The Carba NP test is used for detection of carbapenemase types. This study aimed at applying Carba NP method for rapid detection of P. aeruginosa isolates producing carbapenemase enzymes. Materials and methods: A total of 97 clinical specimens was collected from pa...

BACKGROUND We compared the performance of the modified Hodge test (MHT), Triton Hodge test (THT), Carba NP test (CNPt), simplified Carba NP test (CNPt-direct), blue-Carba NP test (BCT), and carbapenem inactivation method (CIM) for rapid and accurate carbapenemase detection. METHODS The methods were evaluated by using 256 gram-negative isolates, including 197 Enterobacteriaceae (79 Enterobacte...
متن کاملFurther proofs of concept for the Carba NP test.
Recently, Tijet et al. evaluated the Carba NP test (1), which we developed in order to identify carbapenemase producers. Our first study included 316 carbapenemaseand non-carbapenemase-producing Enterobacteriaceae and Pseudomonas aeruginosa isolates (2, 3). Tijet et al. confirmed that this biochemical test has an excellent specificity of 100%, together with an excellent positive predictive valu...
