ABSTRACT

Adult rat snake blood sample and blood smear were received from Aringar Anna Zoological
Park, Vandalur, Chennai. The haematological examination revealed haemoglobin (5 g/dL), packed
cell volume (28%) and total erythrocyte count (7.8 millions/cmm). Differential leucocyte count
revealed heterophil (62%), lymphocyte (33%), monocyte (3%) and eosinophil (2%). Leishman-
Giemsa stained (LG) blood smear revealed the presence of intracytoplasmic sausage shaped
gametocytes in the erythrocytes was confirmed as Hepatozoon sp. like infection. The
haemogregarines found in snakes usually belong to the genus Hepatozoon. Hepatozoon sp. like
infection occurred in the rat snake could be due to the ingestion of the vector or due to bite of
any vectors.
