- Agalaxia contagiosa, lentivírus e doenças iceberg em pequenos ruminantesPublication . Quintas, Helder; Fe Rodriguez, Christian de laAs doenças que abordamos neste manual, agalaxia contagiosa e os lentivírus dos pequenos ruminantes, tal como outras doenças crónicas de caracter insidioso, não são fáceis de erradicar e têm grande importância social e económica. São doenças complexas e a sua presença pode passar despercebida, comprometendo seriamente o bem-estar animal e a viabilidade dos sistemas de produção de ovinos e caprinos. Assim é imperativo evitar o subdiagnóstico e implementar precocemente medidas eficazes para as combater. Este manual visa, de forma clara e simples, fornecer aos técnicos e produtores ferramentas para compreenderem como se comportam estas infeções nos rebanhos, os principais fatores de risco e alguns dos aspetos fundamentais para o seu diagnóstico e controlo.
- Serological screening in the detection of small ruminant Lentivirus infection in Portugal: its importancePublication . Jacob-Ferreira, João; Coelho, Ana Cláudia; Vila, Ana Grau; Fe Rodriguez, Christian de la; Lacasta, Delia; Valentim, Ramiro; Quintas, HelderSmall ruminant lentiviruses (SRLV) are a group of viruses that infect and transmit among ovine and caprine species. These inflict progressive and longstanding infections, the majority as asymptomatic or developing late onset clinical signs. The diagnosis is made up with laboratorial methods and given its importance ELISA tests are essential. Nowadays, in Portugal, there is few information about SRLV infection. The main purpose of this research was quantifying the seroprevalence of SRLV in Portugal.
- Sheep Lentivirus Infection in different production systemsPublication . Jacob-Ferreira, João; Coelho, Ana Cláudia; Vila, Ana Grau; Fe Rodriguez, Christian de la; Lacasta, Delia; Valentim, Ramiro; Quintas, HelderSmall ruminant lentiviruses (SRLV) are a group of viruses that infect and transmit among ovine species. SRLV infection inflict progressive and longstanding infections, the majority as asymptomatic or developing late onset clinical signs. SRLV infection is a serious problem on ovine production, not only for animals’ wellbeing as well to the herd efficiency. Among other exams, laboratorial methods, essentially, are used for the diagnosis. Raising small ruminants has a great social and economic impact, being produced in different manners going from intensive to extensive care. The main aim of this research was quantifying the seroprevalence and associated risk factors to small ruminant lentivirus infection in different production systems.
