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 tenuous links to equine disease have been recorded (although this is thought to 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.
