[Bacteriologic features of urinary tract infections in children in the Sousse area, Tunisia].

Urinary tract infection (UTI) is frequent in childhood. Our purpose is to determine the bacteriologic profile of UTI in children through a retrospective study of 1281 urinary specimens analysed in the Laboratory of Microbiology of F. Hached University hospital of Sousse between 1997 and 2002 (2000 except). The most frequent pathogens recovered were E. coli (71%), K. pneumoniae (10%) P. mirabilis (8%), Staphylococcus (1.6%), P. aeruginosa (1%) and others (2%). E. coli susceptibility to antibiotics was characterised by the high resistance percentage to amoxicillin (60%), to amoxicilline - acid clavulanic (54%) and to cotrimoxazole (40%). The resistance percentage to third generation cephalosporins, to aminoglycosides and to nitrofurane remained very low, respectively of 1.5%, 1% and 1%. High resistance rates among K. pneumoniae strains towards to amoxicillin - acid clavulanic and Cefotaxim, respectively of 63 and 39% were noticed. The resistance percentages to amikacin and cotrimoxazole were respectively of 17 and 65%, but only of 4% to nitrofurane. 70% of P. mirabilis strains were resistant to amoxicillin, 63% of them remained susceptible to amoxicillin - acid clavulanic. No resistance was shown to amikacin against 31% towards cotrimoxazole.
