Molecular characteristics of extended-spectrum beta-lactamase-producing Escherichia coli from the Chicago area: high prevalence of ST131 producing CTX-M-15 in community hospitals.
This study was designed to characterise 30 non-duplicate extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli clinical isolates from the community in the Chicago metropolitan area collected during 2008. The majority of isolates (n=28) were recovered from urine and 2 isolates were from blood. Molecular characterisation was done using the following techniques: isoelectric focusing; polymerase chain reaction (PCR) and sequencing of bla(ESBL); PCR for plasmid-mediated quinolone resistance determinants; identification of ST131; phylogenetic grouping; and replicon typing. Genetic relatedness was determined by pulsed-field gel electrophoresis (PFGE) with XbaI and repetitive sequence-based PCR (rep-PCR) typing. Twenty-six (87%) of the ESBL-producing E. coli were positive for bla(CTX-M) genes (22 CTX-M-15 and 4 CTX-M-14), whilst the remaining 4 isolates produced SHV-2. Twenty-eight isolates (93%) were non-susceptible to ciprofloxacin and 16 (53%) were positive for aac(6')-Ib-cr. Overall, 16 (53%) of the ESBL-producers belonged to clonal complex ST131 that produced CTX-M-15 or CTX-M-14. Molecular characteristics of ST131 showed that it belonged to three distinct but related PFGE clones, was derived from phylogenetic group B2 and contained IncFII type plasmids. These results illustrate that E. coli clonal complex ST131 producing CTX-M-15, CTX-M-14, OXA-1, TEM-1 and aac(6')-Ib-cr has emerged as an important cause of community-onset urinary tract infections caused by ESBL-producing E. coli isolates in the Chicago area.
