Pneumo-enteritis of the sheep. — M. Giiltier has studied 

 a disease in tlie sheep to which, from its principal 

 lesions, he has given the name of pneumo-enteritis, 

 and which, according to this author^ is caused by the 

 germ of the disease of the pig which has just been 

 described. This aftection sometimes occurs in an epi- 

 zootic form in sheep, and may make great ravages 

 in aftected flocks. In several cases the disease had 

 originated in consequence of the introduction into the 

 sheep-folds of swine recently purchased and which 

 had contracted pneumo-enteritis in the market pens. 

 Once established in sheep, it transmits itself with great 

 facility from sheep to sheep. 



The general symptoms consist in lassitude and gen- 

 eral loss of vigor of the affected animals, w^ith inappe- 

 tence, loss of rumination and the appearance of a 

 more or less intense fever. These symptoms are soon 

 succeeded by bloating, fetid and exhausting diarrhoea, 

 cough, accelerated respiration, mucous discharge from 

 the nostrils sometimes streaked with blood, and the 

 special symptoms of a broncho-pneumonia or of a 

 broncho-pleuro-pneumonia. The skin and the visible 

 mucous membranes take a more or less vivid red color, 

 sometimes mixed with hemorrhagic points. In preg- 

 nant females abortion is often observed although the 

 mother does not necessarily succumb to the attacks of 

 the disease. 



The disease may show various degrees of intensity ; 

 it is sometimes very severe and kills in a few hours, or 

 days, sometimes benign and passes unperceived. Con- 

 possess immunising properties. Annates de rinsl. Pasteur, 1 890, p.
