[Epidemiology of urinary tract infection in children in Marrakech]

By its incidence, the polymorphism of its clinical presentation, its potential gravity, the difficulty of realization of urine culture in children, the frequency of the subjacent urologic abnormalities, the urinary tract infection (UTI) is an important problem in paediatrics. This work relates to a retrospective study carrying 121 episodes of UTI in 111 children taken care in paediatrics services of the Teaching Hospital Mohammed VI in Marrakech between March 2005 and March 2009. The age of our children varied between one month and 15 years with an average of 31 months, girls were more touched than boys with a sex ratio at 1.9. E. coli was the most common causative agent in our study (72 %), followed by Klebsiella in 14 % and Proteus in 5.8 % of cases. The study of antimicrobial susceptibility showed that the majority of the isolates were resistant to amoxicilline in 2/3 of cases. Third generation cephalosporins and aminosides kept their effectiveness on the majority of isolates (E. coli was susceptible to 3GC in 91.2 % and to gentamycin in 88 %). E. coli was sensible to the TSU in 54.4 % of cases.
