Plain-English summary

A 16-year-old Paint stallion from Nova Scotia was brought to the vet because he had a fever that came and went, was eating less than usual, seemed very tired, had yellowing of the skin and eyes, swelling in his legs, and swollen lymph nodes under his jaw. Tests showed that he had a specific infection caused by a bacteria called Anaplasma phagocytophilum. The vet treated him with a medication called oxytetracycline, and the horse responded well to this treatment.

Abstract

A 16-year-old Paint stallion was presented with intermittent fever, inappetance, lethargy, icterus, distal limb edema, and submandibular lymphadenopathy. The horse was native to Nova Scotia and had never left that province. Morulae were detected in granulocytes. Ananaplasma phagocytophilum infection was confirmed by serology and polymerase chain reaction (PCR). The horse responded to treatment with oxytetracycline.
