62261-3 Vancomycin resistance vanA + vanB genes [Presence] by Molecular method

Term Description

Qualitative detection of the nucleic acid sequences in the bacterial vancomycin resistance vanA and/or vanB genes in positive blood culture specimens by target amplification and non-probe detection methods, such as melt curve analysis. This assay detects the presence of vanA and/or vanB genes and cannot distinguish between the two. This term was created for, but not limited in use to, the submitter's test kit, FilmArray Blood Culture Identification panel v2.

Part Descriptions

LP105141-8   Bacterial vancomycin resistance vanA+vanB genes
This test is used for the detection of vancomycin resistance genes by multiplex PCR. Vancomycin is a glycopeptide antibiotic used to treat various infections, primarily those caused by gram-positive bacteria. Vancomycin resistance genes were first found in enterococci, and more recently have been found in Staphylococcus aureus. The emergence of vancomycin-resistant enterococci (VRE) and vancomycin-resistant Staphylococcus aureus (VRSA) in hospitalized patients has lead to a restricted use of vancomycin. To date, multiple vancomycin resistance genes have been characterized, including: vanA, vanB, vanC (vanC-1, vanC-2, vanC-3), and VanD. Of the six van types, vanA and vanB are the most resistant to vancomycin, and are the two types that cause VRSA. PMID: 24983424 Source: Regenstrief LOINC

LP265773-4   Bacterial ABXBACT probe.amp.tar
PCR-based Methods for bacterial susceptibility are similar to genotyping for viral susceptibility, in that resistance or susceptibility is inferred based on the presence or absence of specific genetic information that is known to encode resistance to a specific antibiotic or group of antibiotics. For bacteria, resistance is often conferred by genes that are carried on plasmids, which can be transferred from one species to another. These genes encode proteins that specifically inhibit certain antibiotics, such as carbapenems or aminoglycosides. Source: Regenstrief LOINC
