What Is Opp In Sheep?

What Is Opp In Sheep? Ovine Progressive Pneumonia (OPP) is a slowly progressive viral disease of adult sheep caused by an ovine lentivirus. Most sheep do not show clinical signs of OPP, but the sheep that do typically don’t display signs until 2 years of age or older because of the virus’s long incubation period.

How do you treat OPP in sheep? Control of CAE and OPP is aimed at eradicating the viral infection within the herd or flock. CAE and OPP prevention programs include removal of kids or lambs at birth and feeding heat-treated colostrum and pasteurized milk or milk replacer.

How is OPP spread in sheep? Unfortunately, sheep exhibiting any of the presentations listed above can spread the disease through nose-to-nose contact or through infected colostrum and/or milk. Once a sheep becomes infected, they are infected for life. Current testing options for OPP include the AGID and the ELISA test.

What causes ovine progressive pneumonia? Seropositive sheep and goats must be considered infected and capable of transmitting the virus. Transmission occurs most commonly via the oral route, usually by ingestion of colostrum or milk that contains virus, or by inhalation of infected aerosol droplets. Intrauterine infection is thought to occur infrequently.
