Resumo
Considered as one of the main agents of the tripanossomiases, Trypanosoma evansi causes a disease generically know as surra, with wide geographic occurence. This work has the aim to study the electrophoretic profile of the acute phase proteins of goats, experimentally infected with T. evansi. Ten crossbread female goats, around 4 months of age, clinically healthy and serum negative for the presence of antibodies anti-T. evansi (IFAT) were used. The animals were divided in two groups: six were inoculated (G1) intravenously with 2,38 × 10 6 tripomastigotes of T. evansi and four were kept as noninfected controls. The blood for serum was collected daily until the 14 days after inoculation (DAI), weekly up to the 98 th DAI and every two weeks up to the 364 th DAI. The serum proteins were separacted by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDSPAGE). Twenty-one proteins were found in the serum of the goats, eight were nominally identified; phosphorylase, transferrin, albumin, antitrypsin, acid glicoprotein, haptoglobin, hemoglobin, and light chain immunoglobulin.
