    This is a gradual and progressive condition that is rarely caused by an infection (Greenfield 2015). Tissue ischemia may form coagulative necrosis, which is a sign for dry gangrene versus a liquefactive necrosis that indicates wet gangrene. The affected area becomes dry, cold, and eventually turns purple or black due to a lack of blood flow to that part of the body (Goodman 2015). Dry gangrene typically affects the distal extremities, thus it is usually seen at the patient’s fingers or toes.…

    Typical clinical signs of V. vulnificus infections include fever, chills, diarrhea, nausea, vomiting, septic shock, and characteristic skin lesions [15]. These characteristic skin lesions include lower extremity cellulitis with ecchymosis and bullae. Since the organism can cross the intestinal mucosa rapidly, development of bullous skin lesions of the lower extremities can occur within the first 24 hours after onset of illness [16]. This onset if often thought of as an early manifestation of…

    Necrosis occurs as a result of external injury due to cellular injury, bacterial toxin or trauma to a particular area of the body. Necrosis differs from apoptosis in a couple of ways. First, the morphological changes that a cell undergoes are different in necrosis compared to apoptosis. Secondly, apoptosis is highly regulated, however, necrosis is unregulated. The morphological changes that a cell undergoes during necrosis are the swelling of the cytoplasm, irreversible damage to the plasma…

    components into surrounding tissue (121). Key players that help mediate necrosis include ROS, Calcium ions, poly-ADP-ribose-polymerase (PARP), and lysosomal proteases (888). PARP is an enzyme that is responsible for repairing DNA damage, such as strand breaks. Cells that have undergone a traumatic cellular insult typically have damaged DNA. PARP will deplete cellular ATP in an attempt to repair the massive damage to DNA. Several proteases are activated by increased cellular calcium ion…
