General

  • Catarrhal enteritis is particularly common in farm animals, especially in the first few days of life.
  • The combination of the outpouring of protein rich fluid and low absorption produces rapid dehydration and often death.
  • The causes are numerous - some are considered below.

Pathology

  • Hyperaemia of the gut may be visible through the serosa, although there is no external damage.
    • Blood vessels are obvious
    • The whole bowel appears red looking, wet shiny and oedematous.
  • Internally, the mucosa is oedematous with a mucoid appearance.
  • The exudate is initially thin and watery (i.e. serous).
    • The exudate becomes more mucoid and cellular as the condition progresses.
      • Mucus coats the epithelial surface of the gut.
    • As polymorphs enter the bowel contents, they may become quite opaque (i.e. mucopurulent).
  • In older cases of catarrhal enteritis epithelial cells are lost.
    • Villi become stubby.
    • Mucosa may appear quite shiny.
