Animal anatomy, histology, pathological anatomy

6. Pathological diagnosis:
(cattle):

1. 
   Waxy necrosis and gas gangrene of skeletal muscles.
   
2. 
   Serous-hemorrhagic edema and emphysema of the subcutaneous tissue in the area of ​​the affected muscles.
   
3. 
   Serous - hemorrhagic inflammation of the lymph nodes regional to the affected muscles.
   
4. 
   Slight enlargement of the spleen.
   
5. 
   Acute catarrhal enteritis.
   
6. 
   Granular dystrophy of the liver, kidneys and myocardium.
   
7. 
   Rapid swelling of the corpse.
   

Diagnosis:take into account the epizootic situation, the age of the animal, clinical signs of the disease, pathological changes, and the results of bacteriological examination.
7. Differential diagnosis.Differentiate from anthrax, sepsis and malignant edema (wound), acute tympanic scar.
1. For anthrax - morphological signs of sepsis are expressed (septic spleen with sharp softening of the pulp, hemorrhagic diathesis, hemorrhagic lymphadenitis, granular degeneration of parenchymal organs), hemorrhagic enteritis, tarry blood, bloody discharge from natural orifices.
2. For sepsis - find a septic focus (infected wound, purulent endometritis, etc.), morphological signs of sepsis (septic spleen, hemorrhagic diathesis, systemic lymphadenitis, granular degeneration of the liver, kidneys, myocardium). Conducting background research.
3. For malignant edema – necrosis (sometimes gas gangrene of skeletal muscles in the area of ​​the infected wound, serous hemorrhagic edema of the subcutaneous tissue around the wound. A background investigation is carried out.
(sheep and goats):

1. 
   Necrosis and gas gangrene of skeletal muscles.
   
2. 
   Serous-hemorrhagic edema and emphysema of the subcutaneous tissue in the area of ​​the affected muscles.
   
3. 
   Serous - hemorrhagic inflammation of the lymph nodes regional to the affected muscles.
   
4. 
   Hemorrhages under the epicardium and in the intestinal mucosa.
   
5. 
   Slight enlargement of the spleen.
   
6. 
   Granular dystrophy of the liver, kidneys and myocardium.
   
7. 
   Acute catarrhal enteritis.
   
8. 
   Rapid swelling of the corpse.
