| Abstract | |
Sheep industry is a traditional system in Brazil and presents a series of issues that complicate economical exploitation and urgently need solution. In order to reduce losses this research was idealized to carefully study the major bacterial and parasitary reproductive diseases. All animals were submitted to a general and specific reproductive system clinical examination. Blood, semen, abortions, lochia, vaginal discharges, feces, and preputial/vaginal swabs were collected according to the studied disease. It was not possible to isolate any etiological agent from aborted fetuses. The conclusion was that toxoplasmosis was the major disease on São Paulo herds and has the biggest risk factor in abortions, neosporosis would be related to animals that present heat repetition, leptospirosis was observed with low antibodies titles and the most prevalent was Leptospira australis sorovar australis arising from wild animals, campilobacteriosis and brucellosis are both the reproductive diseases with the lowest occurrence in the state. The first endometritis case caused by Histophilus somni. In Brazil was isolated. The first orchitis case caused by Actinobacillus seminis in São Paulo state was isolated. (AU) | |
