- 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.
- Pus is an admixture of dead and dying neutrophils with necrotic cells and a pyogenic agent.
- 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.
