BIOMETRICAL ALTERATIONS OF TRYPANOSOMA-EVANSI ISOLATE IN LABORATORY RODENTS

Biometrical alterations in a horse Trypanosoma evansi isolate were obs erved when passaged in laboratory rodents. The major parasite transfor mation observed was the increase in the total length as a consequence of an increase in some parasite measurements. These transformations pr obably occurred as a consequence of a host change from horse to rodent s. No kinetoplastic forms were observed. (C) 1998 Elsevier Science B.V .
