500 Coecidia in the Intestines. 



does so because he saw the disease come on in cattle after they 

 had l)een in the barn for one or two months. However, since 

 infection may also occur in the barn, Degoix' claim does not 

 seem to be well founded. 



The disease begins immediately with diarrhea and after one 

 or two days the feces show an admixture with blood and mucus ; 

 distinct blood coagula from the size of a walnut to that of a 

 child's fist are also seen; the feces are fetid and sometimes 

 have a cadaverous smell. As soon as hemorrhagic feces appear, 

 there is at first slight, later on intense tenesmus, which may lead 

 to prolapse of the rectum. In other cases normal feces are 

 voided at first, followed by a small amount of coagailated blood, 

 later on feces and blood are mixed and diarrhea supervenes. 



In this stage mild cases soon pass into recovery, partic- 

 ularly in adult cattle; the blood disappears after two or three 

 days, and after a few more days the diarrhea stops. The appe- 

 tite, however, remains capricious for some time. 



In grave cases, particularly in young animals, there is a 

 rapid deterioration of the condition. Tenesmus becomes more 

 severe, the feces become quite fluid, very fetid; they contain 

 larger coagula and shreds of mucus; appetite and rumination 

 are suppressed entirely. At the same time the emaciation pro- 

 gresses rapidly and the gait of the animals becomes staggering. 

 The pulse rises gradually to 70-80 and later on even higher ; the 

 temperature rises to 40° C. and above. Later on the blood dis- 

 appears from the feces, but they often contain lumps of mucus, 

 like croupous membranes, and an ichorous thin fluid. The ema- 

 ciation has now reached a high degree, the eyes are deeply 

 sunken, the animals can no longer stand up and they die from 

 complete prostration. 



Course and Prognosis. The disease runs an acute course 

 of five to ten days, but there are also hyperacute cases in which 

 the animals die within twenty-four hours in convulsions. The 

 appetite sometimes remains poor for a while after disappear- 

 ance of the grave symptoms, so that the animals become much 

 emaciated ; anemia may then become so intense that the patients 

 may die even after five months. In the mild, favorable cases, re- 

 current attacks are quite frequent, but these usually take a 

 benign course. Very mild cases lead to the symptoms of simple 

 acute intestinal catarrh. 



As complications of the disease one can sometimes observe 

 blackleg, convulsions and coma in pregnant animals, lironchitis 

 and pneumonia. 



The prognosis is the more unfavorable, the younger and 

 the weaker the sick animals ; the more rapidly the appetite de- 

 creases, the earlier rumination ceases. Two to four per cent of 

 the sick animals usually succumb to the affection. 



Diagnosis. The occurrence of the disease during the time 

 of pasturing, the almost exclusive affection of young animals,
