Measurement of parainfluenza-3 virus antibody by the single radial hemolysis technique.
نویسندگان
چکیده
A single radial hemolysis assay for parainfluenza-3 virus antibody is described as a simple, sensitive, accurate, and precise alternative to hemagglutination inhibition and serum neutralization tests. A highly significant correlation exists between single radial hemolysis zone areas and hemagglutination inhibition titers of both serum and nasal secretion samples. Antibody conversions equivalent to as little as a twofold rise in hemagglutination inhibition titer are readily and reliably detected in sera and nasal secretions. Single radial hemolysis and hemagglutination inhibition activity was demonstrable in the immunoglobulin G fraction of a hyperimmune parainfluenza-3 virus antiserum.

The use of single-radial-haemolysis for rubella antibody studies.
The use of a single-radial-haemolysis technique for the detection of antibody to rubella virus is described. The single-radial-haemolysis test was compared with the standard HI methods for the detection of antibody to rubella virus. A close correlation between the two methods was observed in a survey of over two thousand serum samples and the study indicated that single-radial-haemolysis was hi...
متن کاملQuantitation and analysis of the specificity of post-immunization antibodies to influenza B viruses using single radial haemolysis.
The single radial haemolysis (SRH) technique detected anti-B/HK/8/73 HA antibody rises in 59-85% of paired sera from persons immunized with different influenza vaccines. In contrast, analysis of the same sera by the haemagglutination inhibition (HI) test indicated significant antibody rises in only 27-54% of paired sera. High levels of antibody were detected to influenza B/HK/8/73 and B/Singapo...

Background: Acute respiratory tract infections, both bacterial and viral, cause 4.5 million childhood deaths worldwide, most of which occur in developing countries. Parainfluenza viruses, of the paramyxoviridae family, are among the common causes of acute respiratory infections, giving rise to 30% of respiratory infections in children before school age. The four parainfluenza viruses that cause...
متن کاملNew tests for characterization of mumps virus antibodies: hemolysis inhibition, single radial immunodiffusion with immobilized virions, and mixed hemadsorption.
Hemolysis inhibition (HLI), single radial immunodiffusion (SRID) with immobilized virions, and mixed hemadsorption tests were used for measuring antibodies against mumps virus. Rabbit hyperimmune sera against mumps and early and late human convalescent sera were analyzed. All three tests identified antibodies against both hemagglutinin and the second major envelope component, hemolysin (fusion ...
متن کاملMeasurement of antibodies to influenza virus neuraminidase by an enzyme-linked immunosorbent assay.
The contribution of influenza A neuraminidase antibodies to the reaction with whole virus in an enzyme-linked immunosorbent assay (ELISA) was assessed by specific absorption of rabbit hyperimmune sera. Although measurable and independent, the effect of neuraminidase antibodies was less than that of hemagglutinin antibodies. Recombinants with an irrelevant hemagglutinin were used successfully as...
