vSome cases have pneumonia, inflammation of the articu- 

 lations, peritonitis, laminitis, hepatitis (inflammation 

 of the liver), or opthalmia (inflammation of the eyes). 

 Tlii^ disease is very frequently found in herds 

 where infectious abortion or tuberculosis exists. 



About 80 per cent, of the cases in foals are fatal ; 54 

 to 90 per cent, in calves and 66 per cent, in lambs. 



Post mortem conditions — Here and there may appear 

 erosions or desquamations and red or congested areas in 

 the mucous membrane of the intestines, and sometimes 

 in the stomach. Catarrhal exudate or pseudo-membran- 

 ous patch'>s may (Kcur on the mucous membrane of the 

 intestines. Peyer's patches may be infiltrated and 

 prominent ; sub-mucous infiltrated, softened, and 

 marked by small red spots (hsemorrhagic spots.) 

 Sometimes hjemorrhages may be found in the 

 small or large intestine or in the stomach. In 

 calves and lambs the desquamation of epithel- 

 ium is most marked near the pyloric end of the fourth 

 stomach. The contents of the intestines may be yellow- 

 ish, Avhite, gray, red, mucou-purulent and very foetid. 

 The intestinal lymph glands are usually enlarged. 



Some cases show inflammatory changes in ihe lungs, 

 liver, peritoneum, kidneys, spleen, heart, articulations, 

 and eyes,

 lar feed, with proper quantity and quality, avoid- 

 ing any or all sudden or radical changes and 

 the extremities of too little and too much feed, will 

 tend to maintain healthy calves, colts and lambs. 



It is always safer and better to milk a cow that is 

 far along in the period of lactation and dilute the milk
