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...
متن کاملSerotypes of Haemophilus influenzae strains isolated from pediatric patients with respiratory tract infections.
Capsular serotypes of 122 respiratory Haemophilus influenzae strains were identified utilizing antigenic examinations (Slide Agglutination Test [SAT] and counter immuno-electrophoresis [CIE]), and PCR method. Results of the two methods were compared to find disagreement. Clinical and bacteriological characteristics of encapsulated strains were analyzed. By utilizing PCR assay, 3 (2.5%) serotype...
متن کاملCross-reactions between Actinobacillus (Haemophilus) pleuropneumoniae strains of serotypes 1 and 9.
Actinobacillus pleuropneumoniae strains of serotypes 1 and 9 were studied for their serological properties by means of agglutination, coagglutination (CoA), indirect hemagglutination (IHA), Co-IHA, ring precipitation (RP), and immunodiffusion (ID) tests. Particulate and soluble antigens of unheated and heat-treated bacterial cells were used in various serological tests. Agglutination, CoA, and ...
متن کاملHaemophilus paragallinarum haemagglutinin: role in adhesion, serotyping and pathogenicity.
It is suggested that Haemophilus paragallinarum requires at least three haemagglutinins for adhesion during infection. This paper reports the partial purification and characterization of the HA-L haemagglutinin from H. paragallinarum strain 46-C3, a heat sensitive, trypsin sensitive haemagglutinin that has been shown to be the serovar specific haemagglutinin in this organism. Using the pl and m...
متن کاملEffects of transformation on the hemagglutinins of Haemophilus paragallinarum.
Strain 0083 and two field isolates of H. paragallinarum were previously converted into NAD-independent organisms by the use of crude DNA extractions from naturally occurring NAD-independent H. paragallinarum isolates. Two of these transformed isolates [0083(T) and A745(T)] were used as DNA donors in another transformation experiment in which another field isolate (M85) was used as the DNA recip...
