Wild hosts include anatidae (ducks, geese and swans) and [http://en.wikipedia.org/wiki/ Coypu] but A.suis can also affect domestic species including cattle, sheep, goats, alpacas, zebu, dogs, cats and tentive links to equine disease have been recorded (although this is thought to be be an ''A.suis''-like microorganism rather than ''A.suis'' itself). ''A.suis'' is not considered to be a zoonosis,but there is a report of a human infection after a pig bite <ref>Escande, F., Bailly, A., Bone, S., Lemozy, J.
