Graciela L. Virulence of the seven Venezuelan animal trypanosome isolates The seven trypanosome isolates showed significant differences in virulence based on the measurement of parasitaemia in infected rats. These spots likely correspond to VSG degradation products, which may be accounted for by the variation in parasitaemia observed between these different trypanosome isolates. Their results supported clonal propagation, and were consistent with the hypothesis that the T. These results indicated that the inositol-1,2-cyclic phosphate moiety of the CRD is only partially responsible for the cross-reactivity of the purified proteins. Also, they were recognized by sera obtained from a buffalo Fig.

    The excluded V 0 and included volumes were determined by chromatographing blue dextran and potassium dichromate, respectively. A dimeric quaternary structure is a common attribute of reported VSGs from salivarian trypanosomes.

    Recently, Fikru et al. The elution volume V e was measured for each protein, and the corresponding distribution coefficient was calculated using the following equation:.

    The purified GM6 antigens were subsequently used in an indirect ELISA that was optimized for detection of trypanosome infection in bovine sera.

    Pays Trop. Moreover, Jackson et al. However, the diagnostic accuracy obtained was lower than that acquired for the full-length native VSG LiTat 1. Despite the high number of VSG and pseudo- VSG genes within the trypanosome genome, each trypanosome expresses only one VSG gene at a time from a telomeric expression site, while the remaining VSG genes are transcriptionally silent.
