Abstract
Conclusions
Only a small amount of the virus of western equine encephalomyelitis is adsorbed upon collodion particles from the clear supernates of virus-containing tissue suspensions during an overnight period in the icebox. This amount is not sufficient to give a positive agglutination reaction with specific antiserum. Experiments with collodion particles sensitized with protein mixtures indicate that it will probably be necessary to concentrate and partially purify the W.E.E. virus in order to obtain collodion particles adequately sensitized for agglutination with virus antisera.
