Effects of bovine viral diarrhea virus on the percentages and absolute numbers of circulating B and T lymphocytes in cattle.
The percentage and absolute numbers of circulating B and T lymphocytes were determined for 10 healthy cattle by labeling mononuclear cells with anti-bovine immunoglobulin or peanut agglutinin. The cattle were then inoculated with a cytopathogenic isolate of bovine viral diarrhea (BVD) virus, and B- and T-lymphocyte populations were again quantitated at given intervals. Seemingly, BVD virus caused a decrease in the absolute numbers of B and T lymphocytes and in the percentage of T lymphocytes. Although these effects lasted through 7 days, all of the cattle recovered from infection and had detectable BVD virus-neutralizing antibodies in their sera 17 days after exposure.
