Abstract

The usual route of transmission of Trypanosoma evansi is through blood sucking arthropods. However, transmission without a vector has been also demonstrated. Experimental transmission of Trypanosoma evansi through unusual ways using expermental animals has been carried out. The results showed that Trypanosoma evansi could penetrate the mucous membrane of the buccal cavity of rats and cats. When these hosts were fed on the flesh of infected mouse, they developed trypa­nosomiasis. Transmission through a very lightly abraded skin of rats was also achieved. There was no evidence of transplacental and transrnarn­mary transmission of Trypanosoma evansi.
