Comparative Study of <em>Mycobacterium avium</em> subsp. <em>avium</em> and <em>Mycobacterium avium</em> subsp. <em>hominissuis</em> in Pigs
In experimentally infected pigs, both subspecies were able to cause infections, according to researchers in Oslo, Norway. They proposed that the more extensive shedding of the hominissuis type might cause pig–to–pig transmission and contribute to the higher incidence of infection caused by this subspecies.
