Reactivity of Haemophilus influenzae type b anti-pili antibodies.

The reactivity of anti-pilus antibodies to native and denatured Haemophilus influenzae b (Hib) pili was studied using rabbit serum prepared against piliated H. influenzae b strain M43 (p+) and adsorbed with its non-piliated variant, strain M42 (p-). The specificity of the adsorbed serum for Hib pili was documented by immunogold electron microscopy and by immunoprecipitation, which revealed the ...

Immunogenicity and Efficacy of Different Haemophilus influenzae type b Vaccines

Haemophilus influenzae, a major cause of meningitis in young children leading to death and other neurological sequelae. The disease leaves 15 to 35% of the survivors with permanent disabilities, such as, mental retardation or deafness. Despite the availability of new and more powerful antibiotics children with Hib meningitis still suffer from high mortality or morbidity. The emergence of multir...

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...

Development of functional Haemophilus influenzae type b antibodies after vaccination.

Sixteen autologous stem cell transplant recipients received three vaccinations with conjugated haemophilus influenzae type b vaccine. Quantitative and qualitative aspects of the antibody response were studied. The vaccination schedule resulted in high antibody response rates and functional maturation of antibodies, as measured by antibody avidity and phagocytosis-inducing capacity.
