Caseous Lymphadenitis

Caseous Lymphadenitis (CLA) a contagious bacterial skin disease of sheep and goats worldwide.

The incidence of the disease increase with age and is more common in intensive production systems.

According to NADIS, the epidemiology of CLA varies between countries. In the UK there is little transmission within the flock but in Australia and the US the transmission can be extreme.

Caseous lymphadenitis is caused by the bacterium Corynebacterium pseudotuberculosis and transmission occurs either directly between sheep during close confinement or, indirectly, through contaminated shearing equipment.
