Lack of virulence factors in Escherichia coli strains of enteropathogenic serogroups isolated from water.

RESUMO
Thirty-eight Escherichia coli strains belonging to 14 human enteropathogenic serogroups were isolated from 33 of 208 water samples studied. No virulence factor or virulence-related gene sequences were found in any of the 38 strains analyzed. The results point out the importance of detecting specific virulence factors before incriminating water as a source of human diarrhea.
