CTX-M-15-producing uropathogenic Escherichia coli isolates at Rio de Janeiro, Brazil: Molecular epidemiology and MALDI-TOF MS.

CTX-M-15-producing uropathogenic Escherichia coli isolates at Rio de Janeiro, Brazil: Molecular epidemiology and MALDI-TOF MS. New Microbiol. 2019 Apr 29;41(2) Authors: Pavoni Gomes Chagas T, da Silva Caldeira LF, Vidal Pedinotti Zuma A, Cassiano de Oliveira I, D'Alincourt Carvalho-Assef AP, Dutra Asensi M, Piffano Costa Pellegrino FL Abstract 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 CTXM- 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 phylotyping 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.
