Part Description

LP113695-3   Carbapenem resistance genes
Carbapenems are stable to AmpC β-lactamases and extended-spectrum-β-lactamases. Carbapenemases are a diverse group of b-lactamases that are active not only against the oxyimino-cephalosporins and cephamycins but also against the carbapenems. Aztreonam is stable to the metallo-β-lactamases but many IMP and VIM producers are resistant, owing to other mechanisms. Carbapenemases were formerly believed to derive only from classes A, B, and D, but a class C carbapenemase has been described.

IMP-type carbapenemases (one of the metallo-β-lactamases)(class B): Plasmid-mediated IMP-type carbapenemases, 17 varieties of which are currently known, found in enteric Gram-negative organisms, Pseudomonas and Acinetobacter species.

VIM (Verona integron-encoded metallo-β-lactamase): A second growing family of carbapenemases, the VIM family, VIM enzymes occur mostly in P. aeruginosa, also P. putidaand, very rarely, Enterobacteriaceae.

Both IMP and VIM hydrolyse all β-lactams except monobactams, and evade all β-lactam inhibitors.

OXA (oxacillinase) group of β-lactamases (Class D): The OXA group of β-lactamases occur mainly in Acinetobacter species and are divided into two clusters. OXA carbapenemases hydrolyse carbapenems very slowly in vitro, and the high MICs seen for some Acinetobacter hosts (>64 mg/L) may reflect secondary mechanisms. They are sometimes augmented in clinical isolates by additional resistance mechanisms, such as impermeability or efflux. OXA carbapenemases also tend to have a reduced hydrolytic efficiency towards penicillins and cephalosporins.

KPC (K. pneumoniae carbapenemase) (Class A): A few class A enzymes, most noted the plasmid-mediated KPC enzymes, are effective carbapenemases as well. Ten variants, KPC-2 through KPC-11 are known, and they are distinguished by one or two amino-acid substitutions

The class A Klebsiella pneumoniae carbapenemase (KPC) is currently the most common carbapenemase.

CMY (Class C): The first class C carbapenemase was described in 2006 and was isolated from a virulent strain of Enterobacter aerogenes. It is carried on a plasmid, pYMG-1, and is therefore transmissible to other bacterial strains. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.
