Hematology has become important for making clinical diagnoses in snakes because maintenance techniques in captivity have been improving and increasing their life expectancy. The emergence of diseases in captivity requires the creation of parameters to understand the species in their healthy state. The possible association between the onset of neoplasia, immunosuppression, and viral infection are also important factors to consider. Thus, hematology is a fundamental tool for observing the responses of animals to diseases and treatments. The present study aims to study hematology between two species of snakes and compare the profiles observed with published results. Blood samples were collected from 16 male and female snakes: seven Corallus hortulanus from the family Boidae and nine Python bivittatus from the family Pythonidae belonging to the Biological Museum of the Butantan Institute, São Paulo, Brazil. Complete blood count results including blood smear, total erythrocyte count, leukocytes, and differential leukocyte count were evaluated. The data obtained in this study could help with the diagnosis, the treatment of snakes in captive conditions and in of nature conservation programs.
