Parasites and Parasitic Diseases of Sheep. 53 
Treatment.—We have little evidence in regard to a satisfactory 
treatment for this worm, but the treatment, including nursing treat- 
ment, given for the preceding species would be worth trying. 
Prevention.—The preventive measures outlined for the thread 
lungworm apply here. 
OTHER INTERNAL PARASITES. 
Various other kinds of roundworms besides those that have been 
mentioned infest sheep, and some of them at times prove very in- 
jurious. The methods of prevention recommended for stomach 
worms, hookworms, and others in this bulletin, will help to protect 
sheep also from these other roundworms. There are also certain 
species of flukes, tapeworms, protozoa, and arthropods, other than 
those discussed here, which are omitted because they are relatively 
less important, so far as we are aware at present.
