Widespread dissemination of CTX-M 15 genotype extended spectrum beta-lactamase producing Enterobacteriaceae among patients presenting to community hospitals in Southeastern United States.

ESBL production was confirmed by both methods in 47 Enterobacteriaceae9. Risk factors and clinical impact of levo-floxacin or cefazolin nonsusceptibility betalactamasa ESBL production among uropathogens in adults with community-onset urinary tract infections. These enzimes can confer resistencia to penicilins, first, second and third generation cephalosporins and aztreonam, and because of their plasmidic nature, they spread easily.
