Transmission studies with Sarcocystis idahoensis of deer mice (Peromyscus maniculatus) and gopher snakes (pituophis melanoleucus) were conducted to determine host specificity of various stages of the parasite. Sporocysts were not passed by four dogs or four cats fed infected skeletal muscle from deer mice. Seven white mice (Mus musculus) and 34 white-footed mice (Peromyscus leucopus) were negative for sarcocysts and liver meronts following oral inoculation with S. idahoensis sporocysts; however, excystation of sporocysts occurred in two white-footed mice killed four hours post inoculation (PI). A gopher snake orally inoculated with sporocysts remained negative for coccidia for two months PI. Three deer mice orally inoculated and three intraperitoneally (IP) inoculated with tachyzoites from liver meronts developed sarcocysts in their skeletal muscles similar to those seen in deer mice orally inoculated with sporocysts. Liver meronts were not found. Ten deer mice orally inoculated and 10 deer mice inoculated IP with bradyzoites from S. idahoensis sarcocysts remained negative for sarcocysts and liver meronts at necropsy 17 days PI.
对鹿鼠（白足鼠）和地鼠蛇进行了爱达荷肉孢子虫的传播研究，以确定该寄生虫各个阶段的宿主特异性。给四只狗和四只猫喂食感染的鹿鼠骨骼肌后，它们均未排出孢子囊。给七只小白鼠（小家鼠）和34只白足鼠口服接种爱达荷肉孢子虫孢子囊后，它们的肌肉囊蚴和肝裂殖体检测均为阴性；然而，在接种后4小时处死的两只白足鼠中，孢子囊发生了脱囊。一只口服接种孢子囊的地鼠蛇在接种后两个月内球虫检测仍为阴性。三只口服接种和三只腹腔接种来自肝裂殖体速殖子的鹿鼠，其骨骼肌中出现了与口服接种孢子囊的鹿鼠相似的肌肉囊蚴。未发现肝裂殖体。十只口服接种和十只腹腔接种来自爱达荷肉孢子虫肌肉囊蚴缓殖子的鹿鼠，在接种后17天尸检时，肌肉囊蚴和肝裂殖体检测均为阴性。
