Application of card agglutination test and card indirect-agglutination antigen test for detection of camel trypanosomosis in western Sudan

A total of 81 blood samples from traditionally managed camels were examined parasitologically and serologically for presence of camel trypanosomiasis in Northern and Southern Kordofan State in western Sudan. Parasitological examinations revealed that only 4 cases (4.94%) were positive. Serological investigations showed that 4 and 14 cases (4.94% and 17.28%, respectively) were recorded as ++ and + for Suratex. The results of CATT indicated that 20, 15, 12 and 13 cases (24.69%, 18.52%, 14.81% and 16.05%, respectively) were reacted as +++, ++, + and ±, respectively). While 4 and 13 cases (4.94%, 16.05%, respectively) were recorded as ++ and + for CIATT. Suratex, CATT and CIATT were found to be 100% sensitive for detection of Trypanosoma brucei evansi infection in camel but high specificity was only recorded for CIATT and Suratex (83.1% and 81.8%, respectively).
