Near-drowning-associated pneumonia with bacteremia caused by coinfection with methicillin-susceptible Staphylococcus aureus and Edwardsiella tarda in a healthy white man: A case report

Abstract

Background: Edwardsiella tarda is an Enterobacteriaceae found in aquatic environments. Extraintestinal infections caused by Edwardsiella tarda in humans are rare and occur in the presence of some risk factors. As far as we know, this is the first case of near-drowning-associated pneumonia with bacteremia caused by coinfection with methicillin-susceptible Staphylococcus aureus and Edwardsiella tarda in a healthy patient. Case presentation: A 27-year-old previously healthy white man had an episode of fresh water drowning after acute alcohol consumption. Edwardsiella tarda and methicillin-sensitive Staphylococcus aureus were isolated in both tracheal aspirate cultures and blood cultures. Conclusion: This case shows that Edwardsiella tarda is an important pathogen in near drowning even in healthy individuals, and not only in the presence of risk factors, as previously known.
