Resumen
Because of the high prevalence of CTX-M-15-producing Escherichia coli isolates causing urinary tract
infections in Rio de Janeiro, we have investigated bla-CTX-M-15 gene presence, as well as CTX-M-15 production, in 32 E. coli isolates recovered from the urine of outpatients assisted at a public hospital located in
the west zone of Rio. Molecular epidemiology was assessed by PFGE and phylo-typing methods. The work
highlights the good performance of MALDI-TOF MS as an alternative tool to detect extended-spectrum
beta-lactamases among CTX-M-15-producing E. coli isolates.
