Comparison of hemagglutinating pili of Haemophilus influenzae type b with similar structures of nontypeable H. influenzae.
Thirty-eight clinical isolates of nontypeable Haemophilus influenzae were tested for the presence of hemagglutinating pili similar to those of H. influenzae type b (Hib) that mediate buccal epithelial cell adherence. Four endogenously hemagglutinating (HA+) strains were identified, and eight additional HA+ variants were obtained from HA- strains by erythrocyte enrichment. All 12 HA+ nontypeable...

ABSTRACT Background: A polymerase chain reaction (PCR) assay with primers from "hpd" gene was compared with culture for the detection of Haemophilus influenzae type b (Hib) in CSF samples from children suspected of meningitis. Methods: 300 cerebrospinal fluid (CSF) samples from suspected meningitis cases were studied by culture (Leventhal & Chocolate Agar) and PCR. Results: The latter...
