Different strains of MAP exist, depending mainly on the
species infected. Infections in cattle and sheep are considered
to be caused by separate strains of MAP, sometimes classified as
type C and type S, respectively. There has been some evidence
of cross-infection of animals between these species (38), but
more research is needed to determine the degree to which these
2 MAP types can actually cross the species barrier. There is also
evidence that wildlife species, particularly rabbits (39), may play
a role in the dispersion of MAP throughout the environment
and cause contamination of feed for cattle (40).
