Decreased antibiotic susceptibility of Enterobacteriaceae causing community-acquired urinary tract infections in French Amazonia

Abstract : Objectives: Urinary tract infections (UTIs) have rarely been studied in the Amazon region. We aimed to describe the epidemiology of bacteria causing UTIs in French Guiana.Patients and methods: We performed a monocenter retrospective study of adults consulting at the emergency department of Cayenne Hospital in 2014 with a diagnosis of UTI. The bacterial species and resistance profile were described.Results: Two-hundred-and-eighty-nine patients presenting with UTI were included: 82 (28.4%) presented with cystitis, 166 (57.4%) with pyelonephritis, and 41 (14.2%) with male UTI. E. coli was predominant (74.1%), and had decreased susceptibility to ampicillin, amoxicillin-clavulanic acid, fluoroquinolones, co-trimoxazole, and furans compared with data from metropolitan France. Extended-spectrum beta-lactamases (ESBL) was isolated in 3.1% of E. coli and 31.6% of K. pneumoniae.Conclusions: Antibiotic susceptibility in UTI is lower than reported in metropolitan France without evidence for an excessive consumption of antibiotics.
