An update on bovine anaplasmosis (Anaplasma marginale) in Canada

Anaplasmosis in cattle, caused by Anaplasma marginale, is a federally reportable disease and has been since December 17, 1969 after Canada’s first outbreak in Manitoba the previous year.
It is widespread globally and is an endemic non-regulated disease in the United States. Anaplasma marginale poses no direct human health or food safety risk.
It is  a disease of ruminants, although only clinically apparent in cattle. Transmission is either biologically by competent ticks or
mechanically (by transferring of blood from an infected animal via biting flies or use of hypodermic needles on multiple animals).
