98064-9Beta-lactam resistance ESBL blaCTX-M-14 gene [Presence] by Molecular methodActive

Term Description

Qualitative detection of nucleic acids within the beta-lactamase CTX-M-14 gene (blaCTX-M-14) found in Gram-negative bacteria. Testing may be performed in addition to conventional culture susceptibility testing to determine the potential bacterial resistance mechanism to antibiotics.

Part Description

LP426519-7   Bacterial beta-lactam resistance ESBL blaCTX-M-14 gene
Extended-spectrum beta-lactamases (ESBL) are enzymes produced by some bacteria that are resistant to the majority of beta-lactam antibiotics which include the penicillins, cephalosporins and the monobactam aztreonam. [https://www.uptodate.com/contents/extended-spectrum-beta-lactamases] Organisms producing CTX-M type ESBL enzymes have been isolated worldwide with more than 150 enzymes identified. These enzymes have been classified into seven major phylogenetic groups: CTX-M -1, CTX-M-2, CTX-M-8, CTX-M-9, CTX-M-25, CTX-M-74 and CTX-M-75. CTX-M-9 group includes CTX-M-14 and CTX-M-15. The rare ESBL type CTX-M-8 has been isolated in Germany, mainly in E. coli, but also in Salmonella and E. aerogenes. CTX-M type ESBL have been isolated worldwide and their incidence has increased dramatically and is still increasing leading to a major therapeutic issue. Currently more than 150 allelic variants of CTX-M have been identified. The dissemination of these enzymes has caused an increased use of carbapenems for treatment of infections which carries its own risk of furthering resistance. [PMID:25234380] The genes are named with the prefix "bla", which stands for "beta-lactam", followed by the enzyme, for example, blaCTX-M-1. Source: LOINC
