Caprine Arthritis and Encephalitis (CAE) is a persistent lentivirus infections of goats that is economically important to the goat industry. The CAE virus infects its hosts for life but most infected animals are subclinical and thus never develop symptoms. However, a minority of infected animals will develop progressive, untreatable symptoms including polyarthritis and mastitis in adults and encephalitis in kids. The virus decreases the lifetime productivity of dairy goats, especially in herds where the prevalence within the herd is high.
CAE is mainly transmitted from infected dams to their kids by the ingestion of virus containing colostrum or milk. Horizontal transmission can also occur by direct contact and exposure to contaminated needles and other instruments. Both asymptomatic and symptomatic animals can transmit the virus.
Producers make significant management and culling decisions based on test results, so the test they use must be accurate and reliable. We offer an ELISA test manufactured by VMRD of Pullman, Washington. The assay has a sensitivity of 100% and specificity of 99.6%.
