Hemagglutination with Certain Arthropod-Borne Viruses.

Abstract
A method for prepn. of hemagglutinins with several arthropod-borne viruses is described. The method is based on the use of brain tissue from newborn mice infected with virus as the source material and on treatment with acetone and ether for the elimination of nonspecific factors. With this method hemagglutinins have been found associated with the following viruses: dengue (Hawaiian type), dengue (New Guinea B type), Ilheus, Japanese B encephalitis, Ntaya, West Nile (Egypt 101 strain), and yellow fever (Asibi strain).
