MYCOTIC OR INFECTIOUS G ASTRO-ENTERITIS. 201 



of soft fecal matters, which are fetid and intermixed with croupous 

 masses of a febrile, flaky, membranous, tubular, or cylindrical 

 form. In the other species the symptoms of intestinal croup are 

 the same as those of simple enteritis, but are less well marked. 



Prognosis. This is not of the same gravity in all the animal 

 species. In the ox it is relatively benign. Cases where the croup- 

 ous exudate succeeds in completely obstructing an intestinal loop 

 are quite exceptional. In other animals, especially the horse, the 

 prognosis is more serious, and the practitioner should be careful to 

 exercise some precaution in this respect. According to Grimm, 

 croupous enteritis is said to be frequently complicated by rheu- 

 matisQi. 



Differential diag'nosis. Croupous neoformations — the only 

 characteristic symptom of the affection — are frequently taken by 

 non-professionals for snakes, tapeworms, or the intestines of small 

 animals that have been swallowed, and even for the patient's own 

 intestinal loops. The grayish-white color of these productions, 

 their amorphous structure and homogeneous consistence, also the 

 absence of traces of mesenteric insertion, etc., permit us to recog- 

 nize their nature at once, and to distinguish them, whatever their 

 form may be, from an intestinal loop. 



In the horse we must not confound the mucous coating of the 

 dung (covered dungs), which is frequently observed in catarrhal 

 proctitis and ordinary constipation, with the false membrane of 

 intestinal croup. In carnivorous aniuials the excrements some- 

 times contain organic matters which are incompletely digested, and 

 these have a certain resemblance to the croupous exudate. 



Treatment. The treatment is nearly the same as that of simple 

 enteritis. However, liquefacients and dissolvents, mainly the alka- 

 line carbonates and sulphates should be preferred to emollients. In 

 the dog especially, these salts administered in clysters (in a solution 

 of 1 : 1 00 of sea-salt or other soda or potash salt) are of much 

 advantage.
