Automation of a flocculation test for syphilis on Groupamatic equipment.
A flocculation reaction employing a cardiolipid antigen was used for syphilis screening on Groupamatic equipment in parallel with conventional screening reactions: Kolmer CF, RPCF, Kahn, Kline, and RPR. The positive samples were confirmed by FTA-200, FTA-ABS, TPI, and in some cases by TPHA. There were 5,212 known samples which had already been tested by all methods and of which 1,648 were posit...
متن کاملSerological tests for syphilis.
Many of the nontreponemal or serological tests for syphilis involve the detection of serum antibodies (reagin) which are not directed against a component of the causative organism itself but may arise as a result of pathological changes brought about by proliferation of Treponema pallidum in host tissue. Test antigens for the detection of reagin are lipoidal, the main active component being the...
متن کاملSerological Tests for Syphilis.
In a pilot study by field-screening in two different sauna baths, a day-sauna and a night-sauna, 318 homosexual men were investigated for syphilis and hepatitis B surface antigen (HBsAg) and its antibody (anti-HBs). Of the 134 visitors to the day-sauna 35 1-o were seroreactive for syphilis, four (3%) carried HBsAg, and 95 (70' 9%) anti-HBs. Of the 184 visitors to the night-sauna 33' 2% were ser...
متن کاملVDRL slide flocculation reaction for syphilis performed on active sera.
The discovery of cardiolipin (Pangborn, 1941a) as the active agent in antigens for sero-reactions for syphilis enabled the production of chemically defined antigens, composed of cardiolipin, purified lecithin (Pangborn, 1941b), and cholesterol. Among the many tube and slide flocculation reactions based on the use of cardiolipin antigens, the Venereal Disease Research Laboratory (VDRL) slide flo...
متن کاملFlocculation tests in hydatid disease.
A new serological technique of diagnosing human hydatid disease, employing polystyrene latex particles coated with hydatid cyst fluid, and a modified technique using bentonite particles are described. Comparison of the latex test with the complement-fixation test performed on 102 sera has shown a total agreement of 98% and an agreement of 93.1% in the positive specimens. The bentonite test and ...
