[Radial hemolysis reaction with arboviruses].

A modification of the radial hemolysis test with arboviruses of the antigenic groups A and B was developed with Sindbis, Chikungunya, Venezuelan equine encephalomyelitis, West Nile, dengue 1 and 2 viruses. Goose erythrocytes were sensitized with hemagglutinating sucrose-acetone antigens of these viruses from mouse brains at pH optimal for each virus.
