Title in Portuguese
Estudo da ocorrência e avaliação  clínica de enfermidades do trato genital de ovinos (Ovis aries, Linnaeus, 1758) criados no estado de São Paulo
Keywords in Portuguese

Campilobacteriosec Leptospirose
Neosporose
Ovino
Toxoplasmose
Abstract in Portuguese
A ovinocultura é um sistema de criação muito antigo em nosso país e ainda continua apresentando uma série de problemas que dificultam a produção econômica desses animais e necessitam de urgentes soluções. Visando minorar estes prejuízos esta pesquisa foi idealizada com o intuito de realizar um estudo minuncioso das principais enfermidades reprodutivas parasitárias e bacterianas. Todos os animais foram submetidos ao exame clínico geral e específico do sistema reprodutor e colheram-se amostras de soro, sêmen, abortamentos, lóquios, secreções, fezes e zaragatoa prepucial e vaginal dependendo da enfermidade a ser estudada. Não foi possível o isolamento nos fetos de nenhum agente etiológico. Conclui-se que a toxoplasmose é a enfermidade de maior importância nos rebanhos de estado de São Paulo e a de maior fator de risco em casos de abortamentos, a neosporose estaria relacionada principalmente com animais que apresentam repetição de cio, leptospirose foi observado em baixa titulação e a mais prevalente foi a Leptospira australis sorovar australis proveniente de animais silvestres, a campilobacteriose e a brucelose são as duas enfermidades da reprodução com menor ocorrência no estado. Foi isolado o primeiro caso de endometrite no Brasil por Histophilus somni. Foi isolado o primeiro caso de orquite por Actinobacillus seminis no estado de São Paulo.

Abstract in English
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.
