Pseudo-Membrajious {Croupous) Enteritis in Solipeds. 221 



It ought to be borne in mind tiiat the habitual microbes of the 

 healthy bowel may become pathogenic when brought in contact 

 with a mucosa which is the seat of irritation, atony or any con- 

 dition of debility. 



Symptoms and Lesions. The verminous aneurisms and throm- 

 bosis aside, the symptoms and lesions of this form of congestion 

 so closely resemble those of the verminous affection that it seems 

 needless to repeat them . 



Diagnosis is difficult but the absence of worms in the affected 

 animals and their fellows, and the presence of some one of the 

 other recognized causes may lead to a fair conclusion. 



Treatment of the affection is more hopeful than in the 

 verminous affection, and may be conducted on the same general 

 lines. 



PSEUDO- MEM BR ANGUS (CROUPOUS) ENTERITIS 

 IN SOLIPEDS. 



Definition. Causes : As in ordinary enteritis, with added infections or 

 toxins. Symptoms: As in enteritis, nervous symptoms, diarrhoea. Lesions: 

 Congested mucosa, whitish or grayish false membranes, in patches or 

 tubular casts, granular, mucous, albuminoid, fibrinous. Diagnosis : False 

 membranes in stools. Treatment : Glauber salts, calomel, alkaline car- 

 bonates or tartrates, oils, antiferments, demulcents, careful diet, bitters. 



Definition. An inflammatory affection of the bowels charac- 

 terized by the ejection with the faeces of false membranes. 



Causes. It has been long attributed to the causes which pro- 

 duce other forms of enteritis and indigestions, as youth, rich 

 stimulating feeding, sudden change to green food in spring, 

 sudden chills, over-fatigue, confinement in-doors, and prolonged 

 co.stiveness. In man it is found as a sequel of infectious diseases 

 (pneumonia, pyaemia), in Bright's disea.se, cirrhosis of the liver 

 and cancer, and in poi-soning by lead, mercury or arsenic (Osier). 

 Cadeac, who found great numbers of streptococci in the false 

 membranes in animals, is certain it is a microbian disease, and 

 this is doubtless true, if qualified by the statement that the 

 microbe as is so often the case with other intestinal affections.
