How do you stop CL in goats?
A strict testing and culling protocol or separation of infected and uninfected goats can be helpful. Managing kids to prevent contact with CL positive dams and heat-treatment of colostrum or pasteurization of milk can help prevent spread.
Is CL in goats fatal?
Unfortunately, it is the internal abscesses that are fatal, whereas external abscesses are the ones generally responsible for disease transmission.
What are symptoms of CL in humans?
As the lesions in lymph nodes grow, abscesses containing creamy white, yellowish, or greenish-coloured pasty pus, rich in bacteria form. These abscesses displace normal tissue and can cause difficulty breathing, eating, and ruminating, depending on the location of the abscess.
Is there a cure for Caseous lymphadenitis?
Caseous lymphadenitis (CLA) is an infectious disease caused by the bacterium Corynebacterium pseudotuberculosis, that affects the lymphatic system, resulting in abscesses in the lymph nodes and internal organs. It is found mostly in goats and sheep and at the moment it has no cure.
Can you vaccinate for CL?
