Modification of the homotypic specificity of poliomyelitis complement-fixing antigens by heat.

Fluid obtained from HeLa cell cultures infected with poliomyelitis viruses served as a complement-fixing antigen. When used in the native state, i.e. untreated in any way, the fluids acted as homotypically specific antigens. When heated, however, the antigenicity was broadened and a high degree of heterotypic reactivity was encountered. Data are presented indicating that the observed group reactivity was apparently based on common antigens shared by the three immunologic types of poliomyelitis virus. This reactivity appeared to be specific for the poliomyelitis viruses. No evidence was obtained in preliminary experiments that heating of the antigens releases a "soluble" antigen responsible for the group reactivity.

A complement fixation test for poliomyelitis.

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 titer. One individual gave a high and equal antibody response to two virus types, 3 others had no detectable antibody, and 1 appeared not to have poliomyelitis. Heterotypic reactions were encountered, but gave little difficulty in interpreting homologous responses. In those patients from whom a virus had been recovered, the serologic findings corresponded to the virus type recovered. The possible occurrence of dual infections with the viruses of poliomyelitis and Western equine and St. Louis encephalitis is discussed.
