Typing of IS 1311 polymorphisms confirms that bison (Bison bison) with paratuberculosis in Montana are infected with a strain of Mycobacterium avium subsp. paratuberculosis distinct from that occurring in cattle and other domesticated livestock.

Abstract excerpt

Isolates of Mycobacterium avium subsp. paratuberculosis from nine bison (Bison bison) from Montana, United States of America, were compared with those from other species from the United States of America. All 16 isolates had a novel IS 1311 genotype in which all copies of the element possessed a thymidine-cytosine nucleotide variation at base position 223. Isolates from bison were termed B strain.
