Hematology and enzyme histochemistry of peripheral blood lymphocytes in domestic pigeon (Columba livia f. domestica).

The purpose of our study was to determine the percentages of alpha-naphthyl acetate esterase (ANAE)-positive and acid phosphatase (ACP)-positive peripheral blood lymphocytes (PBL) in both sexes of one-year-old domestic pigeons (Columba livia f. domestica). Blood samples obtained from 12 healthy domestic pigeons were used. The mean percentages of ANAE-positive PBL for females and males were 47.8% and 48.8%, respectively, whereas the mean percentages of ACP-positive PBL were 67.5% and 68.6%, respectively. The proportions of PBL were 49.3% and 48.6% in males and females, respectively.
