Measurement of Antibodies Reacting with Capsular Antigens of Haemophilus Influenzae.
نویسندگان
چکیده
A simple haemagglutination procedure is described which measures antibodies that react with capsular antigens of Haemophilus influenzae. Abnormally high antibody titres of appropriate type-specificity are common in the blood of human subjects who are known to have carried capsulate strains of H. influenzae. It is not yet clear whether all such antibodies are due to such carriage.

Haemophilus influenzae Type b Meningitis
The age-related acquisition of serum anticapsular and bactericidal antibodies to Haemophilus influenzae type b observed in rats was similar to that of humans. The antigenic source for this "natural" immunity was not identified, since neither pharyngeal infection with H. influenzae b nor enteric colonization by cross-reacting bacteria was detected. Infant rats surviving H. influenzae b bacteremi...
متن کاملAntibody responses to capsular polysaccharide, lipopolysaccharide, and outer membrane in adults infected with Haemophilus influenzae type b.
The antibody response to Haemophilus influenzae type b antigens as capsular polysaccharide, lipopolysaccharide, and outer membrane components was studied by enzyme-linked immunosorbent assay in 10 adults infected with this bacterium. Almost all patients had detectable amounts of immunoglobulins G and M antibodies specific to capsular polysaccharide, lipopolysaccharide, or outer membrane in thei...
متن کاملEffect of heat on antigenicity and immunogenicity of the antigenic determinant shared by Haemophilus influenzae type b and Escherichia coli K100.
Escherichia coli K100 produces an antigenic determinant similar to, or identical with, the capsular antigen of Haemophilus influenzae type b. Studies of the effects of heat on the immunogenicity, erythrocyte-modifying capacity, and antigenicity of this cross-reacting antigen (CRA) revealed the following findings. Immunization of rabbits with viable or formaldehyde-killed suspensions of E. coli ...
متن کاملA study on Haemophilus influenzae type b growth rate and capsule production in different media
In the present study, seven isolates of Haemophilus influenzae type b were cultured in four different media to compare growth rate and capsule production. Four liquid media namely brain heart infusion broth (BHI), trypticase soy broth (TSB), Mueller Hinton Broth (MHB) and Gonococci broth (GC) with added supplements (1% hemoglobin, 1% Isovitalex) were used. The growth was measured by colony coun...

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...
