For the serodiagnosis of syphilis a quantitative passive agglutination (MCA-TP) test for antibodies to Treponema pallidum was performed with chemically stable microcapsules with no antigenic activity instead of with conventional sheep erythrocytes. The microcapsules were easily sensitised with the antigen of sonicated Treponema pallidum by treatment with glutaraldehyde. Compared with the Trepon...

A total of 255 sera were collected from unvaccinated crossbred (174) and indigenous (81) cattle and buffalo having history of respiratory and reproductive disorders. All the sera sample were subjected to indirect ELISA and passive haemagglutination (PHA) test for the detection of BHV-1 antibodies. Indirect ELISA and PHA test detected significantly (P<0.01) varied prevalence of BHV-1 antibody i....

One hundred sera from 49 patients with glandular toxoplasmosis were examined by a latex agglutination test, the dye test, an indirect haemagglutination test, and a double antibody sandwich enzyme linked immunosorbent assay (ELISA) for antitoxoplasma IgM. The results support previous findings that the dye test, indirect haemagglutination test, and latex agglutination test measure different antib...

Four hundred and forty-six patients' sera from a hospital blood transfusion department in Newcastle were examined for toxoplasma antibodies by a haemagglutination test. Forty per cent. of the sera gave positive reactions, and an increase in the percentage of positive sera was found with increasing age, rising to over 60% at the age of 70 and over. A wide range of titres was demonstrated amongst...

Using an ultrasonicate of the Reiter treponeme as antigen the Reiter haemagglutination test (RHA) was evaluated as a serological test for syphilis. Comparison of the results of the cardiolipin Wassermann reaction, Reiter protein complement-fixation test, the fluorescent treponemal antibody-absorbed (FTA-ABS) test, the Treponema pallidum haemagglutination test (TPHA) (at dilutions of 1/16 and 1/...
