Pathology

• The mucosa eroded to produce lesions of darkish-red submucosa covered in dry, crumbly fibrin.
• Is usually caused by severe damage due to secondary bacterial infection following an earlier milder insult.
• Tends to be more severe in the lower small intestine and upper large intestine.
  • Many severe infections tend to get worse further down the gut.
    • Catarrhal change may be seen in the upper small intestine and fibrinous change in the lower small intestines.
  • In the lower aprt of the bowel, where the inflammation is more severe, disease is more anaerobic.
    • Lesions are caused by anaerobic organisms- convert mild diseases into more serious disease.
