title: Biometrical alterations of Trypanosoma evansi isolate in laboratory rodents.
abstract: Biometrical alterations in a horse Trypanosoma evansi isolate were observed when passaged in laboratory rodents. The major parasite transformation observed was the increase in the total length as a consequence of an increase in some parasite measurements. These transformations probably occurred as a consequence of a host change from horse to rodents. No kinetoplastic forms were observed.
