However, CAEV is not just spread via the lactation route, when uninfected does were milked with infected does in the US, a high percentage became infected in less than 10 months ( Adams et al., 1983). Caprine arthritis and encephalitis free#The virus can be in colostrum or milk just as free virus particles or inside cells ( Blacklaws et al., 2004). Colostrum mixed together from different does has been identified as a critical source of spread in herds. The most important transmission route is the ingestion of colostrum and milk by young kids from infected does (known as lactation route). Routes of transmission – how is CAEV spread? Genetic factors of both the host (breed and family-related disease susceptibility) and the virus ( virulence) influence the outcome of CAEV infection ( Peterhans et al., 2004). a kid ingesting infected milk from a doe is the most important mode of transmission of CAEV. There are some countries where SLRVs have never been reported, and some that have managed to eradicate the virus from livestock including Iceland, Australia and New Zealand. It is important to note that natural sheep-to-goat, and goat-to-sheep transmission of CAEV and MVV can occur in mixed flocks ( Reina et al., 2009). MVV also affects the ewes mammary glands but other classical target organs include the lungs and brain. In CAEV infection ( Peterhans et al., 2004) the areas most commonly affected are the joints, although it can also affect the mammary glands which causes significant problems in the dairy goat industry. Caprine Arthritis Encephalitis Virus (CAEV)Īlso known as Small Ruminant Lentivirus (SRLV) or LentivirusĬaprine (relating to goats) Arthritis Encephalitis Virus (CAEV) is a small ruminant lentivirus (similar to Maedi-Visna irus (MVV), a virus found in sheep) which is responsible for major production losses in goats worldwide. Both lentiviruses can transmit between both species, therefore mixed grazing should be avoided on farms affected by either CAEV or MVV.

Method for detecting the presence of the virus in a sample. PCRĭetection of the virus is a rapid, specific and sensitively Titers too low to be reliably detected by serology assays. Serology result does not definitively rule out infection,īecause goats recently infected with CAEV may have antibody Serology positive goats may be free of any clinical signs but However, a positive serology result cannot confirmĬurrent status, and the presence of the antibodies may notĬompletely protect a goat from infections. Testing is routinely used to test goats for past exposure to Is thus important to test goats routinely for infection.
