Conteúdo:	Abstract: The caprine arthritis encephalitis (CAE) is a disease caused by Lentivirus genus, Orthoretrovirinae subfamily, and Retroviridae family belonging to the same human immunodeficiency virus (HIV) family. This viral disease is widespread in the world, affecting especially goat dairy, being easily transmitted by contact among animals secretion, milk ingestion and also through contaminated ejaculate. Has no cure and is difficult to control, since the tests in use are not accurate due to virus latency, providing false negative results. The present study aimed to identify the major seminal plasma protein profile of goats chronically infected by CAE. Two groups containing five males each, aging 4 to 5 years were used. The first group was composed by naturally and chronically CAE-infected animals and the control by seronegative, both confirmed by two blood tests of Western blotting (WB) and by polymerase chain reaction (PCR). The semen was collected through artificial vagina and after that, two-dimensional electrophoresis and MALDI-TOF MS were used. The proteins of high expression identified only in seropositive animals play an important role in the viral infection, such as the protease arylsulfatase A, whose function probably is related to metabolism control of sulfatides, involved to virus control. The other ones were bifunctional ATP-dependent dihydroxyacetone kinase/FAD-AMP lyase, cathepsin F isoform X1, disintegrin and metalloproteinase domain-containing protein 2-like isoform X1, clusterin, carbonic anhydrase 2, electron transfer flavoprotein subunit beta, and epididymal secretory glutathione peroxidase. These results show that seminal plasma proteins are involved on reproductive process protection in chronically infected goats by CAE. As the arylsulfatase A enzyme participates in the physiological events of fertilization in bulls and sheep, and it is absent in seronegative goat to CAEV, probably the main function of this enzyme in goats can be related to metabolism control of sulfatides, involved to virus control.
