GoKawiilA 74-year-old man went to an emergency department in Florida with rapidly rotting limbs after jumping into the waters off Florida’s Gulf Coast.
Just three days earlier, the man was otherwise healthy and active on the coast. But at one point when he jumped into the water, he got a cut on his right leg. It quickly became painful and bruised. Two days later, the skin on his right arm also started changing color.
According to a case report in the New England Journal of Medicine, by day three, when he arrived at the hospital, he was in dire shape. The lower half of his leg was darkly colored, indicating bleeding under his skin. Doctors noted a crackling sound, suggesting gases bubbling out of his dying flesh, and some of the outer layers of skin were peeling off. His arm wasn’t much better. It appeared red, discolored, and swollen. A large blood blister (a hemorrhagic bulla) had formed, suggesting a severe flesh-eating infection. (You can see a graphic image here, including an end image of his arm.)
While the man was rushed into surgery to start cutting out the dead and infected tissue, doctors also began tests to find the cause of the infection. Blood and tissue samples turned up positive for Vibrio vulnificus, a flesh-eating bacterium found in warm, brackish waters.
V. vulnificus can infect people two ways: through wounds exposed to contaminated water—as in the man’s case—or, more commonly, through contaminated seafood. The bacteria can take up residence in the stomachs of shellfish, particularly oysters, as well as the intestines of fish. Either route can be gruesome. When ingested, the bacteria can release enzymes that neutralize stomach acids, then from there storm the intestines and can enter the blood.
