Case Reports

Plesiomonas shigelloides is a rare etiologic agent of bacterial gastroenteritis. Since the year 2000, there is only one published case report of P. shigelloides gastroenteritis. Presented here is a case reporting the typical presentation and successful oral antibiotic treatment of a rarely reported cause of gastroenteritis in the United States, after ingestion of freshwater from a stream in western Pennsylvania.

While not extremely common, Plesiomonas shigelloides is well recognized as an etiologic agent of gastroenteritis. Reported cases, particularly in industrialized countries like the United States, are extremely rare, to the extent that only one case has been reported of P. shigelloides gastroenteritis since the year 2000. While not an abnormal presentation, with a very straightforward treatment and resolution, this case does add to the medical literature of a bacterial infection that is rarely reported.
