Abstract
There is much evidence to indicate that viruses, in certain cases at least, have an antigenic structure of comparable complexity to that of the bacteria. Hughes (1933) found that the serum of animals immunized with the yellow-fever virus contained two independent antibodies—precipitins and protective antibodies; the precipitinogen was distinct from the virus. Craigie & Wishart (1936) in investigations of the vaccinia virus have shown that, in addition to the elementary bodies, virus suspensions contain two soluble precipitable substances, the “L” antigen which is labile at 56° C. and the “S” antigen which is stable at 95° C. These antigens were readily demonstrated by precipitation, agglutination and complement fixation. Their nature and origin have not, however, been precisely determined. Bedson (1936), working with the psittacosis virus, prepared a soluble antigen, which was independent of the elementary bodies. It was most satisfactorily demonstrated by complement fixation.
