A Rare Colonization in Peritoneum After Blunt Abdominal Trauma: S. putrefaciens and S. cerevisiae

Abstract

Background: Shewanella spp. are gram-negative bacteria,saprophytes, and rarely pathogenic. Saccharomyces cerevisiae is thewell-known yeast used for fermentation in industry and molecularbiology for research. In humans, it is a very rare pathogen whichcolonizes the digestive tract, and its utility has been linked to thetreatment and prevention of diarrhea associated with Clostridiumdifficile.Case Report: A 27-year-old male, victim of aggressive, blunt traumawith a 4-day history of symptoms was admitted to our surgery unit.Abdominal sonography revealed peritoneal fluid in all spaces withfibrin. We performed laparotomy and observed perforations on theileum and general peritonitis with pus. Following surgery, patient wasadmitted to the intensive care unit with septic shock. The antibiogramfrom the peritoneal liquid revealed S. putrefaciens and S. cerevisiae.Conclusion: Although very rare, S. putrefaciens and S. cerevisiaemay colonize in the peritoneum after blunt abdominal trauma.
