<unk>  is a tick-borne disease affecting ruminants, dogs, and horses, and is caused by Anaplasma bacteria.<unk>  is an infectious but not contagious disease.<unk>  can be transmitted through mechanical and biological vector processes.<unk>  can also be referred to as "yellow bag" or "yellow fever" because the infected animal can develop a jaundiced look. Other signs of infection include weight loss, diarrhea, paleness of the skin, aggressive behavior, and high fever. There are many different tick species that can carry the bacteria able to cause<unk> , but the two major species include Anaplasma marginale and Anaplasma phagocytophilum. The microorganisms that carry a blood parasite under the Anaplasma genus and cause<unk>  are Gram-negative, and infect red blood cells. Once the host is infected with<unk> , the immune system will try to fight off and kill the infected red blood cells, but will also kill healthy red blood cells. While there are no current live or inactivated vaccines effective for all strains of A. marginale approved by the USDA for<unk> , there are other means of prevention. Tick and fly control for herds of ruminants can be effective but also labor intensive. Chemical methods can also be used, including sanitizing surgical equipment after each use. Tetracycline drugs are the most common treatment for<unk> , and can provide the animal with immunity for a period of time. The disease is more common in the South and West parts of the United States, but is no longer considered a major problem since the use of tetracycline drugs.
