Abstract: Trypanosomes are hemo-flagellate protozoan parasites that cause disease in humans and livestock called sleeping sickness and nagana, respectively. So far, a vaccine has been elusive because of the immunodominant variant surface glycoprotein (VSG) in a phenomenon known as antigenic variation. According to amino acid domains structure, Tc38630 was assumed as a Trypanosoma congolense orthologue of the T. brucei invariant surface glycoprotein (ISG) therefore, a potential diagnostic antigen. Recombinant protein Tc38630 was successfully expressed, characterized and found to be antigenic. Among other serological tests, immunochromatographic test (ICT) has an advantage as a one-step rapid analysis, thus making it a convenient and sensitive diagnostic test .BALB/c mice were immunized with rTc38630 protein and serum was collected for IgG polyclonal antibodies purification for use as control line in ICT. The antigen-antibody reaction was detected by colloidal gold conjugated rTc38630 protein at the test line. The ICT result was found to be consistent with rTc38630 protein-based ELISA. For vaccine studies, five groups of BALB/c mice, were randomized and assigned as recombinant protein, recombinant GST, MCF homogenate, BSF homogenate and PBS and Recombinant Protein from Trypanosoma Congolense ...2Egerton J.

The recombinant protein did not protect the mice (survival analysis, P=0.09).
