- Small 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.
