Heartwater or Cowdriosis in Cattle, Sheep, and Goats
Heartwater or Cowdriosis is a disease of cattle, sheep, goats and wild ruminants endemic to Sub-Sahara Africa, Madagascar, and portions of the Caribbean such as Antigua and Guadeloupe. Heartwater is caused by obligate intracellular rickettsial organisms that parasitize macrophages (a type of white blood cell). After initially replicating in macrophages, the organism will move to the vascular endothelium where it undergoes additional replication.
Rabies in Cattle
Does your cow appear to be choking? Think twice before extending your arm down the animal’s throat bare handed to look for a foreign body. One of the most common ways for ranchers, farmers, and veterinarians to be exposed to rabies is through exposure to a supposedly choked cow.
