SOMATIC TiENIASIS. 
Somatic tseniasis is the infection of any organ with the larval stage 
of a tapeworm. In man we may have the four forms of somatic 
teeniasis mentioned on pp. 9-10. 
Family TiENIIDiE.

Specific diagnosis. See p. 37. 
On p. 39 attention was directed to the fact that Tsenia solium is a more 
dangerous parasite than T. saginatci because of the danger of autoin- 
fection. If, for instance, a patient who harbors T. solium soils his 
fingers with his feces, containing the eggs, and through carelessness 
infects himself with these eggs per os, or if through a reverse peri- 
stalsis a gravid segment of the worm gains access to his stomach, the 
onchospheres (embryos) upon becoming free from their shell, bore 
through the intestinal wall and come to rest in the muscles, e} T e, brain, 
or elsewhere, and develop into the cysticercal stage. In case of infec- 
tion with Tsenia saginata this danger of autoinfection is not present.
