MICROBIOLOGY

  • P. shigelloides is a facultative, anaerobic, Gram-negative rod [Fig] weakly related to the species of Enterobacteriaceae and Vibrionaceae.
    • Previously known as Aeromonas shigelloides
    • Distinguish from Shigella spp. by oxidase test; distinguished from Aeromonas by negative DNAse testing.
    • Non-lactose fermenting, oxidase-positive
  • Ubiquitous environmentally, it can be isolated from soil, usually freshwater, fish, shellfish, and a wide range of animal species.
  • The mechanism of diarrhea due to Plesiomonas shigelloides is unknown. It can produce a cholera-like enterotoxin, thermostable enterotoxin, and thermolabile enterotoxin.
  • Many isolates produce beta-lactamases.
    • Usually susceptible to fluoroquinolones and carbapenems.
