MICROBIOLOGY

P. shigelloides is a facultative, anaerobic, Gram-negative rod 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 fresh water, fish, shellfish and a wide range of animal species.
Mechanism of diarrhea due to Plesiomonas shigelloides is unknown. It is capable of producing a cholera-like enterotoxin, thermostable enterotoxin, and also a thermolabile enterotoxin.
Many isolates produce beta-lactamases.
- Usually susceptible to fluoroquinolones and carbapenems.
