SANTA CRUZ, A et al. Datos morfométricos de Trypanosoma evansi en carpinchos (Hydrochaeris hydrochaeris) de Chaco, Argentina. Rev. vet. [online]. 2013, vol.24, n.1, pp.60-62. ISSN 1669-6840.

The aim of this study was to report morphometric variation of Trypanosoma evansi in Hydrochaeris hydrochaeris bred in captivity in Chaco, Argentina. Biometric measurement was performed on 52 dimensions of T. evansi parasitizing capybaras. T. evansi was present in two different forms, slender and stumpy. Dimensions in both forms were compared with those found in T. evansi parasitizing H. hydrochaeris from the Peruvian Amazonas. Results showed significant differences (p<0,05) in all the variables under study. It is concluded that T. evansi parasitizing H. hydrochaeris from Chaco, Argentina, presents different morphometric dimensions when compared to the same parasite in Peru, showing variations even in the same animal.
