title: Anaplasma phagocytophilum infection (granulocytic anaplasmosis) in a dog from Vancouver Island.
abstract: A 7-year-old Labrador retriever had nonspecific clinical signs that included lethargy, malaise, and difficult ambulation. The dog was native to Vancouver Island, British Columbia, and had never left this area. Morulae were identified in polymorphonuclear cells. Serologic studies and polymerase chain reaction (PCR) testing confirmed canine anaplasmosis caused by Anaplasma phagocytophilum. The dog recovered after treatment with tetracycline.
