The goal of this study was to compare two commercially available total antibody treponemal assays: a conventional TPHA test with an automated CIA run on the random access Siemens Immulite[R] 2000 analyzer.
The syphilis serologic testing for each sample was performed using a RPR test with antigens containing cardiolipin, lecithin, and cholesterol (bioMerieux, Netherlands), a TPHA test with antigens of the Nichols strain of T.
All these nine subjects were also found to be positive when tested with TPHA test.

The aims of this study were to determine and compare the prevalence of syphilis among different patient groups at Weskoppies Hospital, to determine and compare the psychiatric diagnoses of the infected and non-infected, to assess self-reported high-risk sexual behaviour, to establish the co-morbidity between syphilis and HIV, and to investigate the performance of the non-treponemal RPR test as screening method, compared with the confirmatory TPHA test.
MSM patients with positive VDRL and/or TPHA tests and serological follow up of at least 12 months were enrolled in the survey.
