Biliary fever is an illness of the liver affecting horses,[1] dogs[2] and cats.[3]
This is currently the most common infectious disease of dogs in Southern Africa. It is also known as tick bite fever or "Bosluiskoors" in Afrikaans. It is caused by a tiny parasite (Babesia canis) which is introduced into the body by a tick bite. This parasite then enters and destroys red blood cells. Biliary in dogs has a lot in common with malaria in man, except that in the latter, a mosquito is the vector.
