Humoral an cellular immmunity in cows naturally infected with enzootic bovine leucosis virus

Serum and milk samples from naturally infected cows were tested for the presence of antibodies to bovine leucosis virus by immunoenzyme and gel diffusion precipitation test. Using specific monoclonal antibodies total number of CD45 lymphocytes, CD21 B-lymphocytes, CD45CD4 T-lymphocytes, CD45CD8 cytotoxic T-lymphocytes, monocytes and granulocytes was determined.
