1030 . Parasites in the Kidneys. 



Henry & Germain (Rec. 1909, 493) found in a horse, that had been 

 killed on account of repeated attacks of delirium, numerous tubercle-like 

 foci, almost always in the cortical substance, which contained worm 

 larvae similar to rhabditis. The Stephanurus dentatus occurs in pigs 

 (frequently in thelperirenal connective tissue in American pigs). Rost 

 found in 75% of 60 experiment animals nodules in the kidneys, which 

 contained larvae of nematodes (D. m. W. 1906, 446). 



Of tapeworms are found: Cysticercus cellulosae (in pigs; found 

 also once in a dog [Railliet & Trasbot] ) ; Enchinococcus polymorphus 

 (in ruminants, especially sheep ; very rarely in other animals) ; E. 

 multilocularis (found once by Ostertag) ; Taenia serrata (found by 

 Wolpert in both renal pelves of a dog) . Finally Railliet & Lucet have 

 found small nodules containing coccidia in the kidneys of geese which 

 had died with cachectic symptoms; Paechinger mentions a similar find- 

 ing in horses and dogs (Coccidiosis renalis). 



Renal coccidiosis of geese is caused by the Coccidium truncatum 

 (Bimeria truncata) and is manifested in progressive emaciation with 

 extreme debility, owing to which the animals are found sitting almost 

 uninterruptedly. Many animals lie on their backs and spread their 

 feet; if they are stood on their feet they take a few steps and again 

 assume the sitting position. After a prolonged disease they usually lose 

 the desire to eat and die.
