title: Factors affecting the survival of Treponema hyodysenteriae in dysenteric pig faeces.
abstract: Treponema hyodysenteriae was found to survive for periods of up to 48 days in dysenteric pig faeces stored at temperatures between 0 degree C and 10 degree C inclusive. Survival was reduced to seven days at 25 degree C and did not exceed 24 hours at 37 degree C. Dilution 1:10 with tapwater appeared to enhance survival to a maximum of 61 days at 5 degree C but further dilution reduced it. Drying and exposure to disinfectants rapidly eliminated T hyodysenteriae from dysenteric faeces. Phenolic and sodium hypochlorite disinfectants were most effective. The use of these findings in the formulation of control programmes for swine dysentery is discussed.
