CAPRINE ARTHRITIS ENCEPHALITIS VIRUS (CAEV)
Caprine arthritis-encephalitis (CAE) and Maedi-Visna are persistent viral infections caused by lentiviruses belonging to the Retroviridae family.
CAE is a disease that affects caprines, causing arthritis and mammitis in adults and encephalitis in younger animals. Maedi Visna is a disease of sheep, causing shortness of breath or respiratory distress, arthritis and weight loss. In addition, some ovines develop lesions of variable severity in the lungs and on the udders. CAEV and Maedi-Visna are closely related viruses. Although there are only a few documented cases of interspecific transmission, CAEV can infect sheep and Visna-Maedi can infect goats.
The infection is transmitted very early to the lamb or kid in the dams colostrum or milk, or via the respiratory secretions of infected animals. Now a permanent carrier, the lamb or kid can transmit the virus to the rest of the flock throughout its life.
Although ovine lentiviruses have been identified in most countries where sheep are raised (apart from Australia and New Zealand), CAEV is more widespread in industrialised countries. Serological screening for both viruses is required for the certification of caprine and ovine breeding units. Symptoms only manifest in a fraction of seropositive animals (between 9% and 38%, depending on the study).
