Isolation of Mycoplasma mycoides subspecies mycoides from Polyarthritis and Mastitis of Goats in Canada

摘要

The clinical signs, pathomorphological changes, and microbiological findings in Canadian goats infected with Mycoplasma mycoides subspecies mycoides are discussed. The disease affected mainly young goats and was characterized by septicemia and polyarthritis. Mastitis followed by septicemia was seen in two mature goats. The diagnosis was made by culture and identification of the mycoplasma. Infected goats without clinical signs were identified by cultural and serological (complement fixation) techniques. Healthy carriers are presumably able to transmit the infection and may have brought the disease to Canada.
