Which term refers to a localized infection with pus formation?

• A. Inflammation
• B. Absorbable suture
• C. Abscess
• D. Infection

Answer: (C)

Localized infection with pus formation is known as an abscess. An abscess is a confined pocket of pus that develops when bacteria invade tissue and the immune system sends white blood cells to fight them. The dead cells, bacteria, and debris accumulate into a thick fluid called pus, which collects inside a tissue space or organ and is often surrounded by a fibrous capsule to wall it off. Clinically, an abscess appears as a tender, swollen, and warm area; a fluctuant lump may be felt where pus can be drained. This is different from general inflammation, which is the body’s broad response to injury or infection and can occur without pus. It’s also distinct from infection in general, which means microorganisms are present and growing, but not every infection forms a localized pus-filled cavity. An absorbable suture is unrelated to this concept, as it refers to a dissolving material used to close wounds.
