| Abstract: | Trypanosoma vivax (EATRO 1721) organisms were isolated by DEAE-cellulose chromatography from blood of an experimentally infected calf. Attempts to agglutinate the purified trypanosomes with a rabbit antiserum against whole bovine serum or antisera monospecific for bovine IgG1, IgG2, IgM, complement component C3 or albumin were unsuccessful. The trypanosomes, however, were agglutinated by immune sera of four different calves chronically infected with T. vivax (EATRO 1721). It was concluded that T. vivax organisms purified by DEAE-cellulose chromatography from blood of cattle do not have bovine serum proteins on their surface. |
