In Black-and-White cattle, polymorphism of acid phosphatase (AcP) of blood leukocytes is determined by a pair of autosomal alleles. The aim of the study was to determine the relationship between AcP polymorphism and the metabolic efficiency of phagocytes in the first months after calving of cows naturally infected with the bovine leukaemia virus. The studied population consisted of 91 Black-and-White cows aged 3?6 years, from one herd. Enzootic bovine leukaemia (EBL) was diagnosed with the immuno-enzymatic ELISA method and a PCR molecular test. Additionally, agarose gel electrophoresis and the cytochemical method were used to determine the AcP polymorphism and activity in leukocytes. The metabolic activity of phagocytes was determined by the nitroblue tetrazolium (NBT) reduction test. Significant differences in metabolic efficiency of granulocytes were observed between cows representing different AcP phenotypes. No significant differences in levels of the analysed indices were observed between the EBL-positive and EBL-negative cows and between the three subsequent months after calving.
