218 DISEASES OF THE ORGANS OF LOCOMOTION 



CYSTICERCUS INERMIS. 



Definition. — Cysticercus inermis is the juvenile form of the 

 Tsenia saginata of man. Cattle become infested by ingesting 

 the proglottides of the tapeworm found in human feces. The 

 favorite seat of the cyst is in the masseter muscles. These 

 parasites cause no symptoms in cattle. 



MIESCHER'S TUBULES. 



Definition. — These are sarcosporidia (protozoa) that appear 

 in colonies surrounded by a sack-like membrane. They occur 

 in the striated muscles forming elongated sacs which contain 

 a number of kidney- or bean-shaped bodies (sporozoites). 

 The favorite seats are the mouth, throat and esophagus. 

 They produce no clinical sjTnptoms. In rare instances the 

 sac surrounding them may rupture and lead to an invasion 

 of the muscles producing a myositis. This occurs usually in 

 the tongue; or they may induce neoformations in the lumbar 

 muscles.
