Introduction
Equine granulocytic ehrlichiosis (EGE) should be on the rule out list of any horse with persistent fever. Caused by the organism Anaplasma phagocytophilum (previously Ehrlichia equi and also called Anaplasma phagocytophilia) the prevalence of this organism appears to be much wider than seen in the past.
Etiology and Distribution
Anaplasma phagocytophilum is a member of the tribe Ehrlichiae which are closely related to rickettsia. Some of the best-known members are the organisms that cause Potomac Horse Fever, Lymes Disease, and Rocky Mountain Spotted Fever.
Clinical Signs
The incubation time runs one to nine days in experimentally infected horses. Clinical signs are somewhat dependent on age. Most horses under 4 years of age that contract the disease have inapparent to mild symptoms. When clinical signs are evident, fever (102 to 106 degrees) and decreased appetite is the predominant sign and lasts one to nine days.
Diagnosis
The disease can be diagnosed by looking for the organism in the granulocytic blood cells 3 to 10 days after symptoms develop. They appear as small dark staining dots or clusters in the cytoplasm. Anaplasma phagocytophilia is found in membrane-lined vacuoles within the neutrophilic and eosinophilic granulocytes.
Treatment
Horses with no or mild symptoms recover uneventfully without treatment. When clinical signs are severe, treatment can hasten recovery. Like all ehrlichiae they are very sensitive to the tetracycline class of drugs. Rifampin has been used in growing animals to avoid teeth staining.
