Caseous lymphadenitis (CL) is a chronic, contagious disease affecting the lymphatic system of camelids and horses worldwide. It is caused by the Corynebacterium pseudotuberculosis bacterium which results in the development of abscesses in the lymph nodes and internal organs. An abscess may develop at the location where the bacteria entered the goat or at a nearby lymph node; it then continues to spread through the blood or lymphatic system, affecting other body organs and lymph nodes in other areas of the body. It is often found in the lungs, kidneys, and liver.
CL is transmitted from direct contact with infected animals or contaminated fomites or environment.

- Clinical signs
- Haemagglutination test
- IFN-y ELISA
|Surgical treatment||The abscesses need to be either drained or surgically removed by a veterinarian. |
Following reduction of the abscess, the goat should be isolated from other animals for 22 to 30 days, to prevent infecting the remainder of the herd.
|Antibiotic therapy||Rifamyin at 10 mg/kg IM b.i.d. 10d + tetracycline at 20 mg/kg IM every third day|
