Agglutination of Treponema Pallidum in Human Syphilis
The results observed with this strain of Treponema pallidum may be stated as follows: 1. Normal human serum did not agglutinate this culture of Treponema pallidum in dilutions of 1:5 or higher; equal parts of treponema culture and normal serum (dilution 1:2) resulted in agglutination in about 50 per cent of the sera. With the strain of Treponema pallidum used in this study specific agglutinatio...
متن کاملLatex agglutination test for detecting antibodies to Treponema pallidum.
We have developed an automated latex agglutination test for Treponema pallidum (TPLA) for measurement of the concentration of treponemal antibodies in syphilitic sera. The assay needs neither a complicated pretreatment of the sera nor special techniques. Intra- and interassay precision studies showed high reproducibility. Potentially interfering substances, such as bilirubin, hemoglobin, trigly...
متن کاملMicrocapsule agglutination test for Treponema pallidum antibodies. A new serodiagnostic test for syphilis.
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...
متن کاملSpecific Agglutination of Treponema Pallidum by Sera from Rabbits and Human Beings with Treponemal Infections
A method has been described for the preparation of Treponema pallidum suspensions that are suitable for specific agglutination studies and can be stored at 4 degrees C. for months without loss of agglutinability. Such suspensions have been shown to react with two distinct antibodies in the serum of syphilitic animals and man: Wassermann antibody and a specific treponeme agglutinin. It has been ...
متن کاملAntibody Formation against Treponema Pallidum—agglutination
It has been shown by our experiments that the serum of rabbits treated with emulsions of Treponema pallidum contains agglutinating substances. Normal rabbit serum also possesses agglutinating power for this organism, but, as in the case of normal bacterial agglutinins, to an extent very much inferior to that possessed by the sera of immunized animals. Normal human sera will agglutinate similar ...
