[Epidemiological and bacteriological characteristics of uropathogen bacteria isolated in a pediatric environment].
Urinary tract infection (UTI) in children is a grave pathology, which requires a fast and effective care. Bacteriological and epidemiological data play a determining role in patient's care. We report a retrospective study, which spreads out from January 1st till August 31st, 2009, having concerned hospitalized children for urinary infection in pediatrics service of Farhat Hached teaching hospital in Sousse. Our series contained 51 children with a sex ratio of 0.76, an average age of 32 months. The majority of cases was pyelonephritis (94.1%). A pathology is associated with the urinary infection in 41.2%. Three cases of vesico-ureteral reflux were noted. The diagnosis of urinary infection was confirmed by cytobacteriological exam of urine (CBEU). Enterobacteriacea were isolated in 96.1%. Escherichia coli remains the most often isolated (80.4%), followed by Klebsiella pneumoniae (9.8%) then by Proteus mirabilis (5.9%). E. coli was resistant to amoxicillin in 78% of cases, to the association amoxicillin-clavulanic acid in 64,8%, to cephalosporins of 3(rd) generation (C3G) in 5% and to cotrimoxazole in 51%. No K. pneumoniae or P. mirabilis strain was resistant to C3G. UTI in children is always an indication for CBEU realization at first intention. The results of this exam are very important considering the diversity of the responsible bacteria and the growing frequency of acquired antibiotic resistance.
