Trend of Antibiotic Resistance in Children with First Acute Pyelonephritis.

There have been many recent reports of increasing antimicrobial resistance among uropathogens. In this study, we reviewed medical records of children (<18 yr age) with first acute pyelonephritis admitted to our Institution between January 2005 to December 2009. 411 children (189 girls) were studied and increasing trend in bacterial resistance toward co-trimoxazole, 2nd and 3rd generation cephalosporins and gentamicin were observed.
