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.
猪痢疾密螺旋体在温度介于0摄氏度至10摄氏度（含）的条件下储存的痢疾猪粪便中可存活长达48天。在25摄氏度时存活时间缩短至7天，在37摄氏度时存活时间不超过24小时。用自来水按1:10稀释似乎可将5摄氏度时的存活时间延长至最长61天，但进一步稀释则会降低存活时间。干燥和接触消毒剂可迅速从痢疾粪便中消除猪痢疾密螺旋体。酚类和次氯酸钠消毒剂最为有效。文中讨论了如何将这些研究结果用于制定猪痢疾控制方案。
