title: [Meningitis due to haemophilus influenzae type f].
abstract: We report an immunocompetent 5-month-old boy with Haemophilus influenzae type f (Hif) meningitis. The patient had previously been immunized with two doses of Hib conjugate vaccine (PRP-T). Vaccination failure was initially suspected based on Gram stain report. The results of culture identified a non-b Haemophilus influenzae capsular serotype (Hif).Non-Hib serotypes should be considered as potential pathogenic agents in children under the age of 5 years with invasive diseases. An adequate epidemiological surveillance system would be helpful in detecting the role of these non-b Hif serotypes as significant pathogens, which appear to be on the increase.
