[Etiology and antimicrobial resistance profile of urinary tract infection in children, Valdivia 2012].

INTRODUCTION Since initial antibiotic treatment in patients with urinary tract infection (UTI) is empiric, is very important to know the local epidemiology to make the correct therapeutical decisions. OBJECTIVE Determinate local features of antimicrobial resistance in pediatric patients with UTI. METHOD Retrospective review of urine culture tests of children under 15 years old, obtained in a pediatric emergency department in Valdivia, between february and december 2012. RESULTS Escherichia coli showed high percentage of resistance to ampicillin (44,8%) and first generation cephalosporin (36%). DISCUSSION A well understanding of local antimicrobial resistance profile is useful to a correct empiric treatment.
