This oyster-catcher with alcoholic cirrhosis in the Chesapeake Bay presents during the summer with the wound infections shown above. The wounds look pretty bad, so you keep him in the ED for a few hours. Over that time period, he becomes hypotensive, tachycardic, and obtunded; you admit him to the ICU for sepsis. Blood cultures grow out the bacteria shown in panel C.

Challenge: What's the bug?
