Non-diarrheagenic and diarrheagenic E. coli carrying supplementary virulence genes (SVG) are associated with diarrhea in children from Mexico.

Escherichia coli strains, including diarrheagenic E. coli (DEC), are among the most important causes of childhood diarrhea in developing countries. Since these strains also colonize healthy children, additional factors leading to diarrhea remains to be discovered.

Recurrence of infection and diversity of Helicobacter pylori strains in an adult population in Mexico treated with empirical standard triple therapy.

Background: After eradication treatment for Helicobacter pylori, infection could recur due to recrudescence or re-infection. The objective of this study was to determine the recurrence of Helicobacter pylori infection and identify virulent Helicobacter pylori strains one year after eradication with standard triple therapy.

Material And Methods: A quasi-experimental study was performed that included a patient population with digestive diseases associated with Helicobacter pylori who had received standard triple therapy.
