Genetic platforms, bacterial hosts, and ecological contexts enable emergence and restrict dissemination of non-epidemic acquired carbapenemases
Abstract
Carbapenemases are carbapenem-hydrolysing enzymes that remain among the most prevalent drivers of antimicrobial resistance in Gram-negative bacteria,1 some of which, including KPC, NDM, VIM, IMP, and OXA-48-like (also known as the epidemic Big Five), have shown global dissemination. However, dozens of non-epidemic acquired carbapenemases (NEACs) have been described over the past two decades that have not shown major epidemiological expansion.2 These enzymes emerged in clinical or environmental settings and were associated with mobile genetic elements, without establishing a sustained global presence.
