Functional activity of blood lymphocytes and neutrophils in persistent bovine papillomatosis

The functional activity of blood lymphocytes and neutrophils in bulls with persistent cutaneous papillomatosis was evaluated. During clinical manifest ation of papillomatosis, a blastogenic response of lymphocytes to T-cell mi togens significantly decreased. In the regression period of papillomas grad ual elevation of lymphocytic activity was found out and, at the end of eval uation it was comparable with activity of lymphocytes in control animals. T he phagocytic activity of neutrophils in affected animals was not significa ntly altered in comparison with that in control animals. We demonstrated si milar findings by evaluation of leukocyte, neutrophil and lymphocyte counts .
