Parasites and Parasitic Diseases of Sheep. 21 
Distribution.—These tapeworms are more or less common through- 
out the United States. Two of the forms (J/. eapansa and M. 
planissima) are also widely distrib- Re 
uted outside the United States. ‘om 
Symptoms and_lesions.—\When 
these worms are present in sheep 
in large numbers they cause ob- 
struction of the intestine and intes- 
tinal irritation, with the result that 
they interfere with digestion and 
the sheep become unthrifty, weak, 
and emaciated; such sheep are 
unable to stand adverse conditions, 
such as bad weather or poor food, 
and die where sheep not so infested 
may survive. The digestive de- 
rangement is manifested by diar- 
rhea as a rule. It is known that 
tapeworms often cause very marked 
and even severe nervous symptoms 
in man, and while such symptoms 
are more difficult to detect in sheep, 
there is every reason to suppose that 
they may occur. 
On post-mortem examination of 
affeeted sheep the tapeworms are 
found in the small intestine, often 
in large numbers. The sheep show 
no special indications of their pres- 
ence other than poor condition, evi- 
dences of diarrhea, and inflamma- 
tion or catarrh of the intestines. 
Treatment.—There are no well- 
established treatments for tape- 
worms in sheep. Among the reme- 
dies which have been used are the 
following :
