Two assays were used for the detection of trypanosomal antibodies, one using specific anti-camel IgG conjugate and another using a non-specific Protein A conjugate. The third assay detected the presence of trypanosomal antigens using anti-<jats:italic>T. evansi<\/jats:italic> antibodies in a double antibody sandwich assay. Inspection of the frequency distribution of assay results suggested that the ELISA for circulating trypanosomal antibodies using specific antisera and the ELISA for circulating antigens can distinguish between non-infected camels and infected camels exhibiting patent infections or not. The ELISA using Protein A conjugate to bind non-specifically to camel immunoglobulin did not appear to discriminate between infected and non-infected animals.<\/jats:p>","DOI":"10.1017\/s0950268800029976","type":"journal-article","created":{"date-parts":[[2009,5,15]],"date-time":"2009-05-15T09:30:25Z","timestamp":1242379825000},"page":"297-307","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":13,"title":["Evaluation of enzyme immunoassays in the diagnosis of camel (<i>Camelus dromedarius<\/i>) trypanosomiasis: a preliminary investigation"],"prefix":"10.1017","volume":"102","author":[{"given":"P.
