Are all species of bison susceptible?
Yes. There are reliable scientific reports of MCF in both European and American bison (Bison bonasus and B.bison, respectively). MCF occurs in the Plains subspecies (B. bison bison), which is the basis of the commercial bison industry in North America. We are not aware of confirmed cases of MCF in Woodland bison (B. bison athabascae) but we recently found that they are subclinically infected at about the same rate as are the Plains bison.
