Contagious Diseases in Goats: CAE, CL, and Johnes Disease

​

Caprine Arthritis Encephalitis (CAE), Caseous Lymphadenitis (CL), and Johnes disease are significant health concerns for goat owners. These contagious diseases can cause significant economic losses and impact animal welfare.

​

CAE (Caprine Arthritis Encephalitis)

• Caused by: A lentivirus, similar to HIV in humans.

• Transmission: Primarily through colostrum (first milk) from infected dams to kids. Can also spread through contaminated equipment and bodily fluids.

• Symptoms: Arthritis, lameness, weakness, weight loss, udder enlargement, and neurological problems.

• Treatment: No cure. Focus on prevention through testing and culling infected animals.

 

CL (Caseous Lymphadenitis)

• Caused by: The bacterium Corynebacterium pseudotuberculosis.

• Transmission: Through direct contact with infected animals or contaminated environments.

• Symptoms: Abscesses in lymph nodes, often visible externally. Can also cause internal abscesses in organs.

• Treatment: Antibiotics may be used to treat some cases, but prevention is key.

 

Johnes Disease (Paratuberculosis)

• Caused by: The bacterium Mycobacterium avium subsp. paratuberculosis.

• Transmission: Primarily through ingestion of contaminated milk, feces, or soil.

• Symptoms: Chronic diarrhea, weight loss, and decreased milk production.

• Treatment: No effective treatment. Focus on biosecurity measures and preventing the spread of infection.

 

Prevention and Control

• Biosecurity:

  • Isolate new animals.

  • Thoroughly clean and disinfect equipment and facilities.

  • Practice good hygiene.

• Testing:

  • Regularly test animals for CAE and CL.

  • Johne's disease testing can be challenging.

• Vaccination:

  • CL vaccines are available and can help reduce the spread of the disease.

• Culling:

  • Cull infected animals to prevent further spread.

 

Note: This is a brief overview. Consulting with a veterinarian is crucial for proper diagnosis, treatment, and prevention of these diseases in your goat herd.
