Antimicrobial resistance in Haemophilus influenzae isolated during population-based surveillance for meningitis in Salvador, Brazil.

Abstract

Antimicrobial susceptibility was determined for 150 Haemophilus influenzae isolates obtained during population- based surveillance for meningitis in Salvador, Brazil. Ten (6.7%) isolates were resistant to ampicillin and chloramphenicol. Of these, two isolates, a -lactamase and non- -lactamase producer, were resistant to amoxacillin-clavulinic acid. These findings indicate that present antibiotic regimens in Brazil may not be appropriate for the treatment of H. influenzae meningitis.
