Question

Match the type of necrosis with most likely cause.

1) Ischemia
2) Mycobacteria tuberculosis
3) Pancreatic injury
4) Pyogenic bacteria

Answer 1

Gas gangrene, a type of necrosis, is most likely caused by ischemia, which interrupts blood flow and creates an anaerobic environment for anaerobic bacteria to thrive. Traumatic injuries or medical conditions like diabetes can lead to ischemia and gas gangrene.

Step-by-step explanation:

The type of necrosis known as gas gangrene is most likely caused by ischemia, which is a condition where the blood flow to a region of the body is interrupted. This interruption of blood flow creates an anaerobic environment, in which anaerobic bacteria like Clostridium perfringens can thrive and cause tissue death. Traumatic injuries or medical conditions like diabetes can lead to ischemia and subsequently, gas gangrene.
