The two most common manifestations of Haemophilus influenzae type b (Hib) infection in Western communities are meningitis and epiglottitis. The role of antibodies against outer membrane proteins (OMP) in the pathogenesis of these diseases was investigated by Western blotting (immunoblotting) with an OMP antigen prepared from a local Hib strain. Acute- and convalescent-phase serum samples from 25 children with epiglottitis and 20 with meningitis and single serum samples from 19 control children in the same age group were tested. Western blots were evaluated quantitatively by use of graphs generated from a densitometer. OMP antibody was detected in all sera from patients and controls. There wa..View full abstract
