title: Verification of tween-ether antigen for complement fixation test in the diagnostics of toxoplasmosis.
abstract: Tween-ether toxoplasma antigen for the complement fixation test was verified on a more extensive clinical material. From a series of 949 patient's sera, positive reaction was obtained in 44% of samples with the tween-ether antigen and in only 33.5% of samples with the FT antigen. All sera, giving positive results only with the tween-ether antigen, were also positive in the Sabin-Feldman test. The authors believe that by using this type of more sensitive antigen, containing also the cell-wall components of Toxoplasma gondii, it would be possible to standardize serological examination by the complement fixation test on the basis of an international standard serum.
