Editor’s Note: We have just received reports of anaplasmosis in several southern Indiana beef herds. The publication in this link does an excellent job of describing the disease, what causes it, how to minimize exposure risk, and how it can be treated. Dr. Ron Lemenager
Anaplasmosis is an infectious disease of cattle caused by several species of the blood parasite Anaplasma. A. marginale is the most common pathogen of cattle. Anaplasmosis is also called “yellow bag” or “yellow fever” as affected animals can develop a jaundiced appearance.
