]^52 Wliite Scours of Sucklings. 



brane, degeneration of the liver, but no swelling ol the spleen. In 

 the intestinal contents the pyocyaneus is found in almost pure cultures ; 

 the blood on the other hand is sterile. 



5. Proteus bacillosis. This usually occurs when the calf is several 

 days or about a week old and runs a slow course. Feces are fetid, 

 never mixed with blood. On the autopsy the intestinal tract is greatly 

 distended, pale, the mucous membrane becomes macerated shortly 

 after death. The spleen is normal, the mesenteric lymph glands are 

 slightly swollen but not hyperemic. Proteus organisms are present in 

 great numbers in the intestinal contents, but are not found in the 

 blood or in the organs. 



In the cases which are caused by the diplococcus found by Krauts- 

 trunk the autopsy reveals changes similar to those found in colon 

 bacillosis, the intestinal glands being always markedly swollen and 

 reddened. 



Symptoms. In animals born healthy the first symptom 

 usually appears in from 1 to 3 days, exceptionally in a few 

 hours after birth; in rare cases in from 4 to 8 days. The 

 newborn cease to suck and stand in one place with a starin^^ 

 look. They are depressed and lie down a great deal of the 

 time. 



On the first day, or not later than on the second day, the 

 diarrhea appears; the expelled very fluid and fetid feces is 

 yellowish-brown in foals and pigs, while in calves and sheep it 

 is first yellowish, later grayish-white, frequentlj^ foamy, and 

 contains lumps of clotted milk as w^ell as blood streaks (white 

 and red diarrhea). The parts around the anus are soiled and 

 the hair or the avooI is matted. The consistency is at first 

 slightly mucous, later watery; the odor is intensely sweetish, 

 later penetrating, putrid (Hess). The feces are passed at first 

 under severe straining, later it is painless and towards the 

 end of the disease involuntary passing of the feces is observed. 

 Colts suffer severe colicky pains before and after the passing 

 of the feces, they show restlessness, paw with the front feet, 

 look towards the abdomen or they draw the feet under the 

 body. Similar, although not so pronounced, restlessness is 

 observed in calves. At the same time there is bloating, or on 

 the contrary the abdomen may be contracted, the flanks are 

 sunken and the pressing of the abdominal walls causes pains. 

 After the passages the animals stand in one place with feet 

 drawn together, arched back and lowered head, or they lie for 

 a long time motionless on the ground. 



The weakness increases during the course of the disease, 

 the eyes sink into their sockets, the cornea loses its lustre, 

 saliva flow^s from the mouth, the dry tongue is covered with a 

 viscid mucus, the anus is continually open, the hair is rougli, 

 the skin is sticky from the perspiration, the body disseminates 

 a disagreeable sweetish odor, and finally the greatly emaciated 

 animals enter into a comatose state and die. 



At the onset of the disease the body temperature rises 

 from 1 to 2°C. ; later, however, with the appearance of
