A case of anaplasmosis was confirmed in a mare from the Estrie region of Quebec. The mare presented at the end of April 2021 at the University Veterinary Hospital Centre (CHUV) for lethargy, decreased appetite and fever. A blood test confirmed the presence of the bacterium Anaplasma phagocytophilum, responsible for anaplasmosis. This bacterium was also found in an Ixodes type tick found on the mare. The mare had not travelled so the infection is thought to have been acquired locally. The fever resolved after antibiotic treatment. Anaplasmosis is a rare disease in Quebec. It is transmitted by ticks and affects horses, dogs and humans.
