Abstract

A 42-year-old man had nausea, vomiting, periumbilical pain, tenesmus, and diarrhea shortly after eating seafood. Stool microscopy showed "beaver bodies," or Psorospermium haeckelii, a nonpathogenic algal organism often confused with enteric pathogens and commonly found in the excrement of persons consuming crayfish.
