The Treponema pallidum Complement-Fixation Test

Appraisal of the Treponema pallidum haemagglutination test.

Several attempts have been made to use haemagglutination reactions for the diagnosis of syphilis between 1932 and 1958. The first reliable method was developed by Rathlev (1965). Further results of investigations with this method have been reported by authors from Japan and from the Venereal Disease Research Laboratory in Atlanta, U.S.A. Rathlev prepared the reagents for the test in the Statens...

Clinical value of the Treponema pallidum haemagglutination test.

In 1,129 patients attending the Department for Sexually Transmitted Diseases, the serum was examined by three screening tests (VDRL slide, RPCF, and TPHA) and twelve cases of syphilis (1 per cent. of patients attenting the clinic) were discovered. Six of these patients were considered to have latent syphilis (5 acquired, 1 congenital) and were detected only by the TPHA; all six cases were confi...

Shape of Treponema pallidum.

Treponema pallidum was found to be not helical, but a flat wave twisted into one to five different planes per cell.
