This is a severe acute to peracute inflammation in which haemorrhage is the main component.

In purulent inflammation, pus is the predominant feature.
- Pus is an admixture of dead and dying neutrophils with necrotic cells and a pyogenic agent.
  - Proteolytic enzymes released by the dying neutrophils lyse tissue cells to produce a fluid.
Colour varies depending upon the agent.
- May be white, yellow, green or brown.
An abscess is a circumscribed sphere of pus surrounded by a pyogenic membrane.
- The pyogenic membrane is composed of capillaries bringing neutrophils into the sphere.
- This rapidly becomes enveloped by a fibrous tissue capsule.
  - A local connective tissue response attempting to wall off the purulent irritant from nearby normal tissue.

-*  Diphtheritic exudate a more severe form of fibrinous exudate in which  there is considerable necrosis of the underlying tissues.
-* Diptheritic exudate is firmly adherent to the underlying tissue.
-** Attempts at removal cause tearing of this tissue>
-* Commonly seen with internal surface fungal infections.
-** E.g. in the nose of the dog and the guttural pouch of the horse.
-** Fungal toxins penetrate the underlying tissue causing coagulation necrosis.
