A cross-sectional study was conducted in Chilga district, Northwest Ethiopia from October, 2014 to April, 2015 to determine the prevalence and to assess the associated factors of trypanosome infection in cattle. A total of 384 blood samples collected from randomly selected animals were processed using aldehyde test and parasitological examination. An overall prevalence of 6.25 and 5.47% of the trypanosome infection was recorded by aldehyde and parasitological examination, respectively. From infected animals, the prevalence of T. vivax was 90.48% and T. congolense 9.52%. The infection rate was not significantly (p > 0.05) higher in females (5.9%) than males (5.1%) and in adults (5.8%) than young (4.6%) animals. It significantly varied (p < 0.05) among kebeles with 12.1, 6.4 and 1.1% for Negadie-Bahir, Gint and Aykel, respectively. Similarly, the infection rate was also significantly (p < 0.05) higher in poor body condition score animals (23.1%) than in animals with an average score (1.39%). But no infection recorded in good body condition scored animals. Aldehyde test and parasitological examination comparison showed comparable results at 92.7% test agreement. In conclusion, trypanosome infection in the study district was prevalent and it requires wide area coverage epidemiological survey in order to propose suitable control strategies. Moreover, based on the result, in rural settings, Aldehyde test can be used as a diagnostic tool for trypanosomosis where specific diagnostic tests are not applicable.

Key words: Aldehyde test, bovine, Chilga, prevalence, thin smear, Trypanosome.
