Using antigens prepared from cell cultures infected by bluetongue (BLUi virus type 20 (BLU-20), and
sera from cattle which had recovered from experimental infection by that virus, two distinct precipitin
reactions were demonstrated by immunodiffusion. Two distinct gel diffusion precipitin tests were
developed based on these reactions. The antigen of one was common to BLU-20 and two other
Australian BLU isolates, CSIRO 154 (BLU-21) and CSIRO 156 (BLU-l). It was therefore concluded
to be a group-specific test. The antigen of the second appeared to be unique to BLU-20. The test
based on this antigen correlated well with the virus neutralization test for BLU-20 and it was therefore
concluded to be type-specific.
     Similar methods applied to a virus of the Pal yam (PAL) group demonstrated two precipitin reactions
of similar broad (group) and narrow (type) specificity.
