Anti-idiotypic antibody as potential serodiagnostic reagent for detection of bluetongue virus infection

Anti-idiotypic antibody as potential serodiagnostic reagent for detection of bluetongue virus infection.

Polyclonal anti-idiotypic antibodies (anti-Ids) were generated by the sequential immunization of rabbits with three mouse monoclonal antibodies (MAb1s) specific for a major bluetongue virus (BTV) protein, VP7. The anti-Ids, designated RAb2s, recognized idiotopes which were located within or near the antigen-combining sites of the MAb1s and were associated with both heavy and light chains of MAb...

Serological survey of sheep in Iran for Type specific Antibody to Bluetongue virus

Anti-idiotypic antibody as a potential candidate vaccine for Neisseria meningitidis serogroup B.

Sepsis and meningitis caused by Neisseria meningitidis serogroup B (NMGB) are serious diseases in infants and young adults, but no effective vaccine is available. The capsular polysaccharide (PS) of NMGB has poor immunogenicity and a structural similarity to polysialic acid (PSA) on neuronal tissue that may elicit autoantibodies. Using HmenB3, a protective and nonautoreactive monoclonal antibod...

Indication of Anti-HBc Antibody Screening and HBV-DNA Detection in Diagnosing Latent Hepatitis B Virus Infection

Background: In spite of available, and sensitive screening assay for detection of hepatitis B virus surface antigen (HBsAg), occasional cases of post-transfusion hepatitis B virus infection are still observed. The aim of the present study was to assess the prevalence of positive anti hepatitis B core (anti-HBc) and presence of HBV-DNA in serum sample of healthy blood donors negative for both HB...

Anti-Idiotypic Antibodies Specific to prM Monoantibody Prevent Antibody Dependent Enhancement of Dengue Virus Infection

Dengue virus (DENV) co-circulates as four serotypes (DENV1-4). Primary infection only leads to self-limited dengue fever. But secondary infection with another serotype carries a higher risk of increased disease severity, causing life-threatening dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS). Serotype cross-reactive antibodies facilitate DENV infection in Fc-receptor-bearing cells by ...
