Intestinal Parasites of Cattle. 275 



sive actinomycosis of the detni-caual, which had occasioned the 

 choking. Whenever this organism can be diagnosed, here as 

 elsewhere it may be treated with good prospect of success by a 

 prolonged course of potassium iodide. 



FUNGI. 



Saccharomyces Guttulatus. This is normally present in 

 the intestinal contents of cattle, and cannot be accused of any 

 injurious effect. It consists of elliptical cells, of a dark brown 

 opaque appearance and a few brightly refrangent points. They 

 may be isolated, in pairs, or in chains. 



Aspergillus Fumigatus. This fungus, which proves so 

 destructive as a pulmonary parasite of birds and their feeders, has 

 been found in miliary nodules of the small intestine and mesenteric 

 glands of cattle (Franck). The nodules, the size of a pea, were 

 often calcified and were distinguished from tubercles by their 

 greenish color, and by the presence of a central drop of pus mixed 

 with the mycelium of the aspergillus. 



Diagnosis in life is well nigh impossible, otherwise a treatment 

 by potassium iodide, or sulphites would be indicated. Its pres- 

 ence in a carcase should entail its condemnation, as liable to in- 

 fect the human being. 



INTESTINAL SPOROZOA IN CATTLE. 



Cattle suffer from Coccidium Oviforme and Coccidium Per- 

 forans, the ravages of which are described elsewhere. (See 

 Coccidian Enteritis.) 



INTESTINAL TREMATOIDS IN CATTLE. 



Amphistoma Tuberculatum. This is found in the inte.s- 

 tines of cattle in Hindostan. It is a congener of the amphistoma 

 conicum of the rumen, which it resembles. 



Bilharzia Crassa {crassus thick) is a somewhat larger variety 

 of the Bilharzia Hsematobia which lives in the blood of man in 

 Africa and India and produces chylous urine. The ova are more 

 elongated, .16 to .18 mm. are found in papillary elevations of the 

 muco.sa of the urinary bladder, intestines and anus in Egypt
