[Isolation of Plesiomonas shigelloides from a pediatric patient]

We report the isolation of P. shigelloides in the stools of a child with acute diarrhea living in the surroundings of Buenos Aires who usually drank untreated water. P. shigelloides has been implicated as an etiological agent in many sporadic cases of diarrhea, probably associated with drinking untreated water, eating uncooked seafood or foreign travel.
