The gonococcal complement-fixation test (GCFT), based on the same principle as the Wassermann reaction (WR), has been in use for over 60 years. The test was applied for the first time, using a culture of the gonococcus as antigen, by Muller and Oppenheim (1906) to establish the diagnosis in a case of arthritis. Teague and Torrey (1907) suggested that negative results in the GCFT were due to dif...

A macroscopic (tube) complement fixation test for poliomyelitis, using infected tissue culture fluids, is described. The test was applied to 27 individuals with a clinical diagnosis of poliomyelitis. In 18 patients it was possible to make a laboratory diagnosis of poliomyelitis on the basis of a rise in complement-fixing antibody titer and in 4 others on the basis of a high stationary antibody ...

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 ...

Complement-fixing antibody was detected in 13 of 16 patients with histological and/or culture evidence of infection with Nocardia species. The antigen used was a filtrate of soluble substances secreted into liquid growth medium by cultures of N. asteroides. Apparent false positives reactions were found in three of three patients with leprosy and two of five patients with tuberculosis--results ...

For the first time in Iran, a number of 1736 sera samples of wild pigeons which were collected from different parts at Tehran, were investigated to determine the specific antiornithosis antibody using complement fixation test. In this study, 26,5 percent of samples represented ornithosis. 

A Case of Cryptococcal meningitis was diagnosed in a 22 year old Pigeon -fancier from Mazandaran prm ince of Iran (close to the Caspian sea). The patient was treated with systemic 5-nuoc to,;in and amphotericin B together with intrathecal injection of ampho. B. Further investigations showed an abnormal reduction in the number ofT-lymphocytes, while humoral immunity was maintained in the normal ...

Two methods of performing serological screening tests for syphilis are compared. One consisted of the Venereal Diseases Reference Laboratory (VDRL) slide test, the cardiolipin Wassermann reaction (CWR), and the Reiter protein complement fixation test (RPCFT) performed manually; the other was a fully automated system using two Technicon AutoAnalyzers (AAII), one for the automated reagin test (AR...
