Abstract: Trypanocidal drug sensitivity studies were
conducted to assess the efficacy of Diminazene
diaceturate (Diminasan®) and Bis (aminoethylthio) 4-
melaminophenylarsine dihydrochloride (Cymelarsan®)
against T. evansi of Colombia strain in experimentally
infected mice. Study was undertaken from November
2008 to April 2009. Diminazene diaceturate at dose range
of 3.5, 7.0, 14.0 and 28.0 mg kg1 body weight failed
completely to cure Trypanosoma evansi. All the mice
died due to sever parasitaemia. From the present study the
minimum dose necessary to achieve 100 % cure in at least
3 mice for diminazene diaceturate is >28.0 mg kg1 body
weight. However, mice treated with Cymelarsan® at
higher doses of 0.5, 1.0 and 2.0 mg kg1 body weight
becomes effective treatment for Trypanosoma evansi
Colombia strain in mice with no relapse for at least two
months. The result obtained from this study will be
important for designing similar study of in vitro assay to
detect drug resistance against the available isolates of
T. evansi from camel rearing areas of Ethiopia.
