| Abstract: | Summary Five NCP-BVD strains, isolated from clinical cases of BVD and 3 similar strains recovered from non-inoculated BET cultures were found to produce plaques in BET-monolayers under agar overlay when kept at room temperature in the dark for several days after staining.These plaque-forming agents were identified as BVD by neutralization with a BVD antiserum prepared in rabbits.The NCP-BVD strains New York-1 and Sanders-78 also produced plaques in this cell system. |
