Anaplasma phagocytophilum Infection in Horses

Infection with A. phagocytophilumis a tick-borne infectious disease spread by Ixodes species ticks. This infection often occurs from spring through fall due to increased tick activity during this time of year. Illness usually occurs shortly after the tick bite. Affected horses may suddenly show signs such as appetite loss, fever, lethargy (tiredness), reluctance to move, and fluid accumulation on the lower limbs, which indent when pressed with a finger. Affected horses often develop a fever of 103°F or higher (normal temperature range for adult horses: 99°F to 101.5°F). If your horse suddenly develops these signs, it is important to contact your veterinarian. Usually, only one horse on a property is infected with A. phagocytophilum; however, multiple horses on one property are occasionally affected.
