A study was conducted to determine the morphological and biometric characteristics of Trypanosoma
isolated from 50 capybaras animals, raised in captivity in the Peruvian Amazon. Trypanosoma
was found in 14 blood samples using the microhaematocrit, wide drop, and Giemsa-stain methods and T. evansi
was identified through morphological details in all 14 positive samples (the subterminal kinetoplast, the developed undulating membrane, and a long free flagellum were used for the identification of the agent).
