A cluster of cases of Escherichia coli O157 infection in a day-care center in a communal settlement (Kibbutz) in Israel.

Abstract

This is the first report in Israel of a cluster of cases of diarrhea associated with the isolation of Escherichia coli O157 in stool samples. E. coli O157:NM (nonmotile), producing verotoxins 1 and 2 was isolated from the stool samples of three infants less than 1 year of age with diarrhea and from a fourth asymptomatic infant staying in the same day-care class in a communal settlement (kibbutz). The clinical presentation included nonbloody diarrhea without other symptoms. Surveillance efforts should be enacted in order to define the relative importance of E. coli O157 infections in Israel.
