Gangrene is a type of tissue death caused by a lack of blood supply. [4] Symptoms may include a change in skin color to red or black, numbness, swelling, pain, skin breakdown, and coolness. [1] The feet and hands are most commonly affected. [1] If the gangrene is caused by an infectious agent, it may present with a fever or sepsis. [1]
Gas gangrene (also known as clostridial myonecrosis [1]) is a bacterial infection that produces tissue gas in gangrene. This deadly form of gangrene usually is caused by Clostridium perfringens bacteria. About 1,000 cases of gas gangrene are reported yearly in the United States. [2] Myonecrosis is a condition of necrotic damage, specific to ...
Clostridium perfringens is the most common bacterial agent for gas gangrene. [47] Gas gangrene is induced by α-toxin that embeds itself into the plasma membrane of cells and disrupts normal cellular function by altering membrane structure. [43] Some symptoms include blisters, tachycardia, swelling, and jaundice. [47]
“For example, Group A strep is a major cause of flesh eating infections, as is clostridium perfringens, which causes gangrene. These are bacteria that live in on our bodies.”
Diabetic foot infection is any infection of the foot in a diabetic person. [2] The most frequent cause of hospitalization for diabetic patients is due to foot infections. [ 3 ] Symptoms may include pus from a wound, redness, swelling, pain, warmth, tachycardia , or tachypnea. [ 4 ]
In case of sepsis, the bacteria reaches the skin via the bloodstream. Defective humoral or cellular immunity increases risk, as the organism is not cleared from the bloodstream as usual. The main mechanism of the organism that is causing the typical skin lesions is the invasion of the organism into the arteries and veins in the dermis and ...
Clostridium perfringens causes a wide range of symptoms, from food poisoning to cellulitis, fasciitis, necrotic enteritis and gas gangrene. [16] [17] Clostridium tetani causes tetanus. Several more pathogenic species, that were previously described in Clostridium, have been found to belong to other genera. [6]
The most common cause of foot pain is wearing ill fitting shoes. Women often wear tight shoes that are narrow and constrictive, and thus are most prone to foot problems. Tight shoes often cause overcrowding of toes and result in a variety of structural defects. The next most common cause of foot disease is overuse or traumatic injuries. [3]
