Pathological diagnosis:

1. 
   Catarrhal-hemorrhagic, necrotic (erosive-ulcerative) inflammation of the abomasum and small intestine, serous edema of their walls.
   
2. 
   Serous and serous-hemorrhagic edema and emphysema in the subcutaneous and intermuscular tissue in the head, neck, chest, and abdomen.
   
3. 
   Serous and serous-hemorrhagic inflammation of the mesenteric, portal and perinephric lymph nodes.
   
4. 
   Serous-fibrinous pleurisy, peritonitis and pericarditis.
   
5. 
   Granular dystrophy of the liver, kidneys, myocardium.
   
6. 
   Focal (nodular and nodose) necrosis in the liver.
   
7. 
   Slight enlargement of the spleen.
   
8. 
   Hemorrhages in the mucous membrane of the abomasum, small intestine, trachea, bronchi, endocardium and epicardium.
   
9. 
   Rapid decomposition of a corpse.
   

Diagnosisare made taking into account epizootological data of clinical symptoms, pathological changes and bacteriological examination. An epidemiological feature of bradzot is that animals get sick more often in the cold season.

7. 
   Differential diagnosis.It is necessary to exclude:
   

1. Anthrax -morphological signs of septicemia are clearly expressed, carbuncles are found in the skin, mucous membranes, rapid swelling of the corpse is noted, blood is tar-colored, uncoagulated, bloody discharge from the anus, nasal and oral cavities. A bacteriological study and precipitation reaction with the skin and internal organs are carried out.
2. Anaerobic enterorotoxemia -serous-hemorrhagic inflammation of the abomasum and small intestine. The spleen is slightly enlarged, the kidneys are softened (necrotizing nephrosis). Conduct a bacteriological study.
3. Emphysematous carbuncle -necrosis and gas gangrene of skeletal muscles, serous-hemorrhagic edema and emphysema of the subcutaneous tissue in the area of ​​the affected muscles, the spleen is slightly enlarged, rapid swelling of the corpse. Conduct a bacteriological study.
