Abstract

The prevalence and distribution of Trypanosoma evansi (T. evansi) infection on camels in Somaliland were studied using the card agglutination test (CATT/T. evansi). A total of 2575 camels were surveyed. The overall animal-level apparent (test) prevalence in Somaliland was 26.4%. The prevalence was highest in the Sahil Region (37.3%) followed by Togdheer (28.4%), Sanaag (27.4%), and Sool (26.2%). There was a significant difference in the seroprevalence between the regions (χ2 = 35.2, df = 1, P < 0.001) with the prevalence being significantly higher in Sahil than in Woqooyi Galbeed and Awdal, respectively. Camels from the eastern districts were two times more likely to be infected than camels from the western districts (P < 0.001). Herds in the coastal area were also more likely to be infected (37.0%) than herds from the inland areas (26.9%).The seroprevalence varied significantly between body condition score groups (P < 0.001) with the highest seroprevalence in camels of poor body condition (39.5%) and the lowest in camels of good body condition (18.4%) score. Animals in poor body condition were almost three times more likely to be positive than animals in good body condition (OR = 2.9; 95% CI 2.2, 3.8).
