Septicmmia Hmmorrhagica of Cattle. 83 



anaemic, pale, and wasted conditions of the body generally, and 

 the numerous minute centers of purulent infection. The stomachs 

 are well filled, the intestines contain pultaceous and gaseous 

 matters, the glands of the duodenum, of I^ieberkuhn and of Peyer 

 are gorged and when compressed, the latter throw out drops of 

 white purulent matter. The liver is normal, the spleen 

 atrophied, and the kidneys pale and fibrous. The chest shows 

 pleurisies with extensive exudation, sometimes pneumonia or 

 broncho-pneumonia, or atelectasis or even sclerosis. 



Lesions. Wasting Form. The carcase shows extreme emacia- 

 tion, absence of fat, bldbdlessness, with atrophy and even cir- 

 rhosis of liver, spleen, kidneys and other internal organs. The 

 mesenteric glands are large, soft and very watery. In the lungs 

 the most characteristic lesions are calcifications surrounding the 

 alveoli and bronchioles, which have a branching arrangement, 

 crepitate when pressed under the finger, and strongly fix aniline 

 dyes. In the large arteries extending outward from the semi- 

 lunar valves on both sides, the intima is thickened and raised 

 in irregular patches which may become soft like atheroma, or 

 hard and cartilaginous, or calcified. The auriculo-ventricular 

 valves may even be involved and the inner coat . of the auricle, 

 especially the right. In some cases the arteries generally are 

 calcified even to the smaller trunks, and this may be felt in the 

 carotids during life. 



Prevention. The most promising course is to segregate the af- 

 fected animals where their products cannot reach places accessible 

 to other cattle, and to exclude sound cattle from already infected 

 fields until years after drainage. The obvious precaution of 

 sterilizing infected carcases and manure is demanded. 



Treatment. Medicinal treatment fails notably in checking the 

 diarrhoea. Yet lyignieres claims complete success from intra- 

 venous injection of I to 15^ qt. of the following :• boiled water 

 1000 grams : common salt 9 grams : soda sulphate 4 grams. A 

 second injection is made if diarrhoea persists. Improvement ap- 

 • pears after 48 hours, and in 5 to 10 days the bowels are normal. 

 This will temporarily invigorate, but will the improvement last ?
