This research aimed to investigate the seroprevalence of <em>Trypanosoma evansi</em> and its associated risk factors in dromedary camels in North Al-Sharqiya governorate in the Sultanate of Oman.  A total of 4364 serum samples was collected from three willayat in north governorates of Sultanate of Oman; Ibra (926, 21.2%), Qabil (1119, 25.6%) and Bidiyah (2319, 53.1%). Samples were examined for the presence of antibodies against <em>T. evansi</em> using card agglutination test (CATT/<em>T. evansi</em>). Binary logistic regression was used to study the association of <em>T. evansi</em> seroprevalence and risk factors such as location, gender, purpose and age of camels. The overall seroprevalence of <em>T. evansi</em> detected by CATT/<em>T. evansi</em> test was 38% (1659/4364, CI: 36.6-39.5%). There was a significant difference (<em>p</em>=0.001) between location and <em>T. evansi</em> seroprevalence, whereas highest seroprevalence was found in Ibra (49.9%, CI: 46.7-53.1%) followed by Bidiyah (35%, CI: 33-36.9%) and Qabil (34.5%, CI: 31.8-37%). Camels from Ibra were almost two times more likely to have circulating antibodies of <em>T. evansi</em> than camels from Bidiyah (OR=1.89, CI: 1.591-2.168). Also, the results showed a significant difference between seroprevalence and sex (<em>p</em>=0.023), whereas the age of camels was not (<em>p</em>>0.05). To our knowledge, this is the first research that indicated that <em>T. evansi</em> antibodies were circulating among camels in Oman, and further research needs to be tackled to study the molecular characterization of <em>T. evansi</em> and its prevalence in other animal species. Furthermore, cross-sectional studies of <em>T. evansi</em> from different regions in Oman warrant further investigation.</p>}, number={2}, journal={Journal of Agricultural and Marine Sciences [JAMS]}, author={Al-Kharusi, A.H. and Elshafie, E.
