LUNG FLUKES IN THE DOG. 



Dogs appear to sufEer to some extent in Japan, as already quoted 

 from Friedberger and Frohner. Railliet in 1890 found in the 

 Japanese veterinary exhibit in the Paris Exposition, specimens of 

 these flukes taken from the bronchi of a dog. Killicott found, in 

 1894 i" ^ dog dissected at Columbus, O. , a large number of these 

 flukes. The entire surface of the pleura was marked by small 

 brown spots, and on the lobes of the lungs, but especially near 

 the roots, and along the dorsal borders, were rounded tumors of 

 a deep red color, contrasting strongly with the pink of the lung 

 tissue, and enclosing the parasites, with some purulent debris. 

 Some were embedded deeply in the lung tissue, with or without 

 a distinct fibrous capsule. The worms were from 15 to 20 mm. 

 in length. The lung tissue contained great numbers of elliptical 

 ova, especially in the vicinity of the encysted worms, where they 

 gave their own brown hue to the parenchyma. They were also 

 abundant under the pleura, both pulmonary and parietal, causing 

 the brown spots that have been already referred to. Ward, who 

 examined Killicott' s specimens, pronounced them to be the same 

 as his own specimens from the cat, and as the Japanese Paragoni- 

 mus. Nothing of the antecedents of the dog is recorded, and 

 occurring, like the Ann Arbor cat, at a centre of learning it might 

 be suspected that it had been infested indirectly, by human vic- 

 tims who had come from the east. The later discovery of the 

 disease in American pigs lessens somewhat the force of this hypo- 

 thesis. 



LUNG FLUKES IN THE PIG. 



The first specimens of these were sent to the Bureau of Animal 

 'Industry in Sept., 1898, from Cincinnati, by Dr. A. J. Payne. 

 These came from the lungs of a single hog, the source of which 

 could not be traced. In October, Payne found 35 more infested 

 hogs, and in the first weeks of November i per cent, of all the 

 hogs killed at the station harbored the worms. He reported 3 or 

 4 cases during the latter half of November, 4 cases in December, 

 and I in January. In all. Dr. Payne reported 52 ca.ses, though at 

 no time after the dates mentioned were many found at one time.
