Transmission experiments with Treponema hyodysenteriae were conducted with mice and pigs, using laboratory mice as the carrier host. Mice were intragastrically inoculated with T hyodysenteriae and placed in a contact with nonexposed mice or healthy pigs. Contact mice mingled with infected mice at 5 or 180 days after inoculation were shedding T hyodysenteriae in their feces 9 to 14 days after exposure. Pigs exposed directly to infected mouse feces were shedding T hyodysenteriae in their feces after 5 to 17 days of exposure and developed swine dysentery after 11 to 13 days. Transmission of T hyodysenteriae to pigs through direct contact with feces from infected mice indicates that rodents in the field may be a reservoir host and may also be involved in spreading swine dysentery.
利用实验小鼠作为携带宿主，对猪痢疾密螺旋体进行了小鼠和猪的传播实验。给小鼠经胃接种猪痢疾密螺旋体，然后将其与未接触过该病原体的小鼠或健康猪放在一起。接种后5天或180天与感染小鼠混在一起的接触小鼠，在接触后9至14天粪便中排出猪痢疾密螺旋体。直接接触感染小鼠粪便的猪，在接触5至17天后粪便中排出猪痢疾密螺旋体，并在11至13天后患上猪痢疾。通过直接接触感染小鼠的粪便将猪痢疾密螺旋体传播给猪，这表明野外的啮齿动物可能是储存宿主，也可能参与猪痢疾的传播。
