It is shown by complement fixation studies with protein antigens and specific immune rabbit sera that the rate of fixation of complement is determined by the concentration of antibodies in the immune sera, that the greater part of fixation of complement takes place during the 1st hour, and that fixation is practically completed at the end of 4 hours at ice box temperature. It is further shown t...

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. 

Interest in the Reiter strain of Treponema pallidum, a nonpathogenic, cultivatable, anaerobic spirochete, has been stimulated by the demonstration that the organism possesses four antigens; one, a thermolabile protein, being group specific for treponemes (D'Alessandro et al., 1949). This antigen has recently been employed in a Reiter protein complement fixation test for syphilis (Cannefax and G...
