RESUMEN
Vibrio vulnificus is a Gram-negative bacterium which is found in marine environments and where there is a partly enclosed coastal body of water with one or more rivers or streams flowing into it, and with a free connection to the open sea. The infection by these bacteria can cause primary septicemia by two mechanisms: upon consuming crustaceans, mollusks and some fish (filtering shellfish) raw or barely cooked or by an open injury in contact with seawater. The patients with infections of the primary injury by Vibrio vulnificus developed contaminated painful cellulitis that progresses quickly as well as a marked local inflammation with signs of hemorrhaging. We described a case of Vibrio vulnificus sepsis, with emphasis on the clinical picture, the epidemiological background and lab findings; finally we did a brief review of the literature related to the case.
