Cae Vaccine For Goats

Caprine arthritis and encephalitis virus (CAEV) infection is manifested clinically as polysynovitis-arthritis in adult goats and less commonly as leukoencephalomyelitis (progressive weakness, ataxia, proprioceptive deficits) in kids. Subclinical or clinical interstitial pneumonia, indurative mastitis (“hard udder”), and chronic wasting have also been attributed to infection with this virus. However, most CAEV infections are subclinical. Infection with CAEV decreases the lifetime productivity of dairy goats and is a barrier to exportation of goats from North America.

CAEV infection is widespread (seroprevalence rate > 65%) among dairy goats in most high-income economies such as Canada, Norway, France, and the US, whereas it is comparatively rare among indigenous goat breeds raised in lower and middle-income countries, except where there is a history of contact with imported goats.


Caprine arthritis encephalitis (CAE) virus is a member of the small ruminant lentiviruses (also includes ovine progressive pneumonia, or OPP, of sheep), which may lead to chronic disease of the joints, and on rare occasions, encephalitis in goat kids less than six months of age. The CAE virus is intimately associated with white blood cells; therefore, any body secretions that contain blood cells are potential sources of virus to other goats in the herd. Since not all goats that become infected with CAE virus develop clinical disease, it is important to test goats routinely for infection by means of a serologic test that detects viral antibodies in the serum.

Caprine arthritis-encephalitis (CAE) is now considered one of the most significant diseases affecting the goat industry in the United States. It is caused by a lentivirus, a type of retrovirus, which is a family of pathogens responsible for many immunodeficiency diseases in many species, and most breeds of goats are susceptible. CAE causes multiple diseases in goats: arthritis, pneumonia, mastitis and weight loss in adults, and encephalitis (inflammation of the brain and brain stem) in kids.

Features of Cae Vaccine For Goats

The CAE virus is transmitted naturally in the neonatal period from an infected adult doe to the kid through consumption of colostrum and milk. Transmission from the pregnant doe to the fetus is a possibility, and there is evidence to suggest that CAE can also be transmitted directly from goat to goat, possibly through saliva and nasal secretions. Other suspected routes include urine and feces, semen, milking machines and failure to use clean instruments on each animal for tattooing, vaccinating, drenching, etc. 

The encephalitis form of CAE virus is most common in kids 2 to 4 months of age and is characterized by paralysis that may or may not progress to seizures or death. A common symptom of the disease is “head-pressing,” when the animal stands with its head pressed against a wall or other object. The arthritic form is most common and is seen in adult goats 1 to 2 years of age. Affected goats gradually lose weight and develop a poor hair coat and enlarged joints Early in the course of the disease, affected animals may show progressive and sometimes shifting leg lameness. However, as the disease advances, affected goats may walk on their knees and refuse to rise. A presumptive diagnosis can be made based on the history and clinical findings, taking into consideration the age of the animal and disease pattern. Serological tests are available for diagnosis and screening of herds.

CAE can be spread through contact with milk, saliva, or mucous of infected animals, via coughing, and possibly via other routes if infected and healthy goats are mingled. More research is needed on additional routes of transmission, but until the research is available, it is safest to assume that any contact with infected goats, bodily fluids of infected goats, shared airspace or ventilation, or sharing equipment with infected goats may transmit CAE.

To prevent the spread of CAE in your herd you will need to control the spread of these body fluids. The virus can survive outside the body until the fluids have dried up, meaning if a goat coughs and leaves mucous on the wall or drops milk or birthing fluids on the floor it has the potential to infect goats for several hours. This means that using the same alleyways or handling equipment for infected and uninfected goats can spread disease, even if the goats never see each other.
