THE TAPEWORM LARV.E 215 



is harbored by the dog, rarely the cat, infection of man and domestic 

 animals is by the dissemination of the eggs of this tapeworm with the 

 excrement of its hosts. It follows that all hydatic viscera in slaughter- 

 ing establishments or elsewhere should at once be destroyed by burning, 

 thus preventing the larval tapeworm heads from reaching the intestines 

 of dogs and cats. Where the disease has appeared it is a good precau- 

 tionary measure, though often impractical, to administer taeniafuge 

 treatment (p. 186) at repeated intervals to all dogs in the vicinitj*. 

 During the treatment the animals should be confined where their fecal 

 material can be carefullv collected and burned.
