Swine Dysentery. Swine dysentery (SD), is caused by a spirochaetal bacterium called Brachyspira hyodysenteriae. This organism causes a severe inflammation of the large intestine with a bloody mucous diarrhoea (i.e. dysentery). Disease is common in pigs from 12 to 75kg but severe cases occur occasionally in sows and their sucking piglets.
