The purpose of this study was to determine the percentage of peripheral blood T lymphocytes and the localization of ANAE enzyme at the electron microscopic level in Van cats by using an alpha-naphtyl acetate esterase procedure. Peripheral blood samples taken from 20 Van cats were used. The percentage of ANAE positive lymphocytes was 83.0%. Neutrophilic granulocytes gave a negative reaction, whereas monocytes, eosinophilic granulocytes showed a diffuse granular positivity. In the electron microscopic examination, ANAE positive reactions were seen in lysosomal granules found in lymphocytes.
