RESUMEN
OBJECTIVE: To characterize the pediatric patients presenting at the two pediatric centers in Bogotá, with first isolate urine culture of community-acquired extended-spectrum b-lactamase (ESBL)-producing enterobacteriaceae. METHODS: Review of microbiological data of children between January, 2012 and December, 2018, obtained using the WHONET software. RESULTS: A total of 2657 Escherichia coli, Klebsiella spp and Proteus mirabilis - positive urine cultures were obtained within a 6-year period; data of 132 patients were finally selected. Frequency of ESBL-producing bacteria infections in community-acquired urinary tract infections (UTI) was 5%: 123 E. coli (93.2%), 7 K. pneumoniae (5.2%), 1 K. oxytoca (0.8%), and 1 P. mirabilis (0.8%). CONCLUSION: A predominance of female sex, preschool children, and lower tract urinary infections were found, as well as a low frequency of comorbidities. Adequate sensitivity to amikacin and nitrofurantoin was found in this study.
