' Post Mortem Lesions 



Intestinal form: The abdominal and pecto- 

 ral muscles show infiltrations and petechiae, 

 the intestinal mucous membrane is hyperemic, 

 thickened and covered with a brownish red ex- 

 udate. The lungs congested and the pleural 

 cavities filled with reddish exudate. There is a 

 sero-fibrinous pericarditis, the pericardial sac 

 containing a blood-stained fluid. The liver is 

 slightly enlarged and the spleen congested. 



Pneumonic form : The nasal and bronchial 

 mucous membrane is congested, the lungs 

 pneumonic and the pleura covered with a 

 fibrinous exudate. The liver is much congest- 

 ed, but little alteration is seen in the spleen. In 

 both cases the blood is tarry and decomposi- 

 tion sets in rapidly after death. 



Treatment 



No treatment has proved of value. Prophy- 

 laxis consists in good hygiene and sanitation 

 and the use of bacterins.
