Can septicemia and gangrene be linked together?

cause 1 is blood poisoning and the other is dead cell tissue?

All right the first two answers are basic understanding and well good. Now, lets break it down. If a patient presents with a cut, minor lets say, but left untreated and becomes infected. As the infected cut gets more colonizing bacteria, in some instances if left untreated the bacteria can spread to the blood stream. If the bacteria over grows in the blood stream the patient can then become septic. High fevers, low b/p, tachycardia etc. Now back to our cut. If the bacteria that led to our nasty infection causes some disruption in the blood flow that provides oxygen and nutrient to the once healthy tissue, the tissue will begin to show signs of distress. As the oxygen levels deplete, the tissue will slowly die. It will develop necrotic, dead tissue and gangrene will be the result. If untreated or untreatable or unresponsive to treatment, the gangrene can spread and lead to death of surrounding tissue. Look at diabetics who have poor healing abilities. That is why they tell them to check their feet for cuts and scrape. If bacteria invades, it can lead to gangrene. It can start with a toe and end with a whole leg needing to be amputated.

gangrene is an infection which results in necrotic or dead tissue...so obviously gangrene can cause septicemia.

Well... Clostridium perfringes causes gas gangrene, not only does the tissue die, bubbly welts form.

I guess it could if the bacteria gained access to the blood stream and was allowed to get a toe hold, just like other bacteria.
