What is the medical term meaning tissue death followed by bacterial invasion and putrefaction?

The medical term meaning tissue death followed by bacterial invasion and putrefaction is gangrene.

When tissue is injured or diseased, it can become deprived of oxygen and nutrients, leading to tissue death. This process is known as necrosis. If necrotic tissue is not removed, it can become a breeding ground for bacteria. The bacteria produce toxins that break down the tissue and release foul-smelling gases, causing the tissue to rot. This process is known as putrefaction.

Gangrene can be caused by a variety of factors, including:

- Infection (such as clostridial myonecrosis)

- Injury

- Diabetes

- Peripheral artery disease

- Sickle cell anemia

- Raynaud's syndrome

- Buerger's disease

Gangrene can be a serious medical condition, and it can be fatal if not treated promptly. Treatment typically involves antibiotics to kill the bacteria, surgery to remove the dead tissue, and wound care.
