Swine dysentery is caused by a group of strongly beta hemolytic spirochete called Brachyspira (previously called Serpuline or Treponema) hyodysenteriae … The disease occurs more frequently during the growing/finishing periods.

World Animal Health Publication and Handistatus II (dataset for 2002). Some sows might not show any symptom during several months and transmit the disease to their piglets.The high cost of the disease is associated with mortality (low), morbidity (high), decrease in growth, increase in feed conversion ratio, and the cost of in feed medication.The incubation period in field cases is normally 7 to 14 days, but it can be up to 60 days. Involvement of a lipopolysaccharide in the pathogenesis of Treponema hyodysenteriae. Phenotypic and molecular characterization of Brachyspira spp. A variety of antibacterials, such as tylosin, nitroimidazoles (dinitroimidazole, metronidazole, ronidazole), lincomycin, virginiamycin, tiamulin, olaquindox and carbadox, have been used successfully over the years in the treatment and prevention of SD.

Fluid imbalance is the result of failure of the colon to absorb fluid, much of it from endogenous secretions, and explains the progressive dehydration and deaths that occur.
In the United States, SD now occurs only occasionally because of successful eradication and/or effective manure removal techniques.

The second report of this virus was in the United States in February, 2014. Much of the extensive research on the disease was reported during the 1970s and 1980s.
