Particularites bacteriologiques des infections urinaires chez l'enfant dans la region de Sousse, Tunisie

ABSTRACT

Urinary tract infection [UTI] is frequent in childhood. Our purpose is to determine the bacterioiogic profile of UT1 in children through a retrospective study of 1281 urinary specimens analysed in the Laboratory of Microbiology of F. Hached University hospital of Sousse between 1 997 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 catrimoxazole [40%]. The resistance percentage to third generation cepha-losporins, 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 clovulonic. No resistance was shown to amikacin against 31% towards cotrimoxozole
