important causes of childhood diarrhea in developing countries. Since these strains also
colonize healthy children, additional factors leading to diarrhea remains to be discovered.
We therefore conducted a comprehensive study to investigate if supplementary virulence
genes (SVG) carried by DEC strains and non-DEC strains, contribute to diarrhea in Mexican
children. E. coli strains were isolated from n= 317 children between 6 and 12 years, n= 114 …
