title: Utility of antimicrobial susceptibility testing of multiple Haemophilus influenzae isolates from throat swabs of children with adenoid hypertrophy.
abstract: Eleven out of 40 children with adenoiditis were colonized with multiple genotypes of Haemophilus influenzae. Heterogeneous antibiotic susceptibility to ampicillin and cotrimoxazole was observed in 6 children. A multiple-colony methodology may potentially help to find the resistant strains of H. influenzae in patients who do not respond to the antibiotic treatment.
