Lethargy, Fever, and Anorexia in a Thoroughbred Weanling

Allen Page

A 5-month-old Thoroughbred weanling filly presented in November with lethargy, fever, and partial anorexia. On physical examination, the filly was quiet and had a fever of 103.7°F (39.8°C), slightly decreased skin turgor, and dark pink mucous membranes with a capillary refill time of 2 to 3 seconds. The filly also had edema below the mandible, in the distal limbs, and in the ventral abdomen. A complete blood count revealed changes indicative of a stress leukogram, including a neutrophilia and lymphopenia. Click here to read the whole case.
