Integron class 1 reservoir among highly resistant gram-negative microorganisms recovered at a Dutch teaching hospital

Infect Control Hosp Epidemiol. 2009 Oct;30(10):1015-8. doi: 10.1086/606039.

Abstract

Integrons play an important role in the dissemination of resistance genes among bacteria. Nearly 70% of highly resistant gram-negative bacteria isolated at a tertiary care hospital harbored an integron. Epidemiologic analysis suggests that horizontal gene transfer is an important mechanism of resistance spread and has a greater contribution than cross-transmission to levels of resistance in settings where highly resistant gram-negative bacteria are endemic.
