Abstract
Bluetongue virus, BT(8), and the virus of epizootic hemorrhagic disease (EHD) of deer, NJ-55, were plaque purified and compared electronmicroscopically and serologically. The latter included a plaque reduction neutralization test, the agar gel precipitin test, and the complement fixation test. The viruses were indistinguishable morphologically, but antigenically different. A plaquing technique was described for EHD virus.
