Previous issue date: 2013-02-27 / CAPES / FAPERJ / This study aimed to determine from the protein profile of oocysts of Cystoisospora felis recovered from the sequential use of various purification techniques adapted for specific use in sporulated oocysts of C. felis. With the aid of SDS-PAGE 12% resulted in identification of 25 groups of protein: 266, 240, 186, 165, 140, 119, 112, 105, 98, 90, 78, 55, 47, 42, 37, 35, 30, 27-28, 25, 22, 19, 18, 16, 14 kDa belonging to the structure of sporulated oocysts and sporozoites of C. felis. Based on this results and heterologous bovine serum anti-C. felis was possible to determine polypeptides dominant relevant to diagnostic immunoassay technique with "Western Blotting", these being immunodominant bands: P208, P138, P113, p106, p62, p56, p51, p48, p44, p38, p36, and p33 p27. In order to avoid misdiagnosis from cross-reactivity a positive control serum anti-C. felis was compared to with positive serum anti-Toxoplasma and Neospora in order to exclude the common protein bands, probably markers of gender and group to identify cattle infected naturally or experimentally with C. felis. As showed, the following specific antigenic protein units: p 206-208, P137-139, p112- 113, p104-107, p27-28 are responsible for determining the animal tested positive or not for Cystoisospora felis. Of the analysis of the variables could be observed that the presence of felines related to the handling, size and type of milking properties facilitates dispersion C. felis. / Este trabalho teve por objetivo, diagnosticar a infec??o por Cystoisospora felis em bovinos atrav?s do Western Blotting, apartir de oocistos obtidos com o uso sequencial de v?rias t?cnicas de purifica??o adaptadas para o uso em oocistos esporulados de C. felis. Com o aux?lio do SDS-PAGE a 12 % resultou na identifica??o de 25 grupos proteicos de: 266; 240; 186; 165; 140; 119, 112, 105, 98, 90, 78, 55, 47, 42, 37, 35, 30, 27-28, 25, 22, 19, 18, 16, 14 KDa, pertencentes a estrutura dos oocistos esporulados e esporozoitas de C. felis. Com base nesse resultado e em soro de bovino heter?logo anti-C. felis foi poss?vel determinar os polipept?deos dominantes relevantes ? t?cnica de diagn?stico imunoenzimatico com ?Western Blotting?, sendo estas, as bandas imunodominantes: p208, p138, p113, p106, p62, p56, p51, p48, p44, p38, p36, p33 e p27. A fim de evitar o diagn?stico equivocado a partir de rea??es cruzadas foi feita a compara??o do soro controle positivo anti-C. felis com o soro positivo anti-Toxoplasma e Neospora com o intuito de excluir as bandas proteicas comuns, prov?veis marcadoras de g?nero e grupo para identifica??o de bovinos infectados de maneira natural ou experimental com C. felis. Sendo evidenciadas, as seguintes unidades proteicas antig?nicas espec?ficas: p 206-208, p137-139, p112-113, p104-107, p27-28 respons?veis por determinar a positividade dos animais testados para C. felis. A partir das an?lises das vari?veis foi poss?vel observar que a presen?a de felinos associados, ao manejo, tipo de ordenha e tamanho das propriedades facilita a dispers?o de C. felis.
