SYMPTOMS AND DIAGNOSIS 35 



sembling coccidian tumours in the intestine of a 

 sheep." Some were deposited in the centres of the 

 regions of Lieberkuhn's glands, which were hyper- 

 trophied and dilated. The symptoms reported were 

 "sudden onset of the disease, refusal of food, rapid 

 emaciation and decubitus, and death in convulsions in 

 three days." Hertzog states that the symptoms in sheep 

 are similar to those in cattle, but that the coccidia are 

 not found in the faeces. In the acute stages in cattle 

 the presence of the coccidia in the faeces, and in 

 sheep the discovery of the coccidia in the intestinal 

 mucosa on post-mortem examination, should serve to 

 differentiate this condition and Johne's disease. 



Tubercular Enteritis. — According to Friedberger 

 and Frohner, from statistics of researches made 

 throughout the German Empire, tuberculosis of the 

 intestines is found in i per cent, of cattle suffering 

 from tubercular disease. 



Nocard, writing of tuberculosis in cattle, says : 



It is not rare to find miliary tubercles de- 

 veloped within the thickness of the mucosa, or 

 in the submucous cellular tissue of the intestines. 

 These tubercles may be isolated or agglomerated ; 

 in either case they quickly undergo softening, and 

 empty their contents into the intestinal canal, thus 

 causing a small wound of the mucosa, which has 

 no tendency to heal ; these ulcers, at first small 

 and isolated, generally tend to spread. Such 

 lesions are especially numerous in the last portions 

 of the small intestine and in the caecum. Perfora- 

 tion of the intestine is quite exceptional. . . . 

 Intestinal and mesenteric tuberculosis causes fre- 

 quent colic with profuse diarrhoea, alternating with 

 obstinate constipation.
