MELO-JUNIOR, Mario R. et al. Lectin staining patterns in human gastric mucosae with and without exposure to Helicobacter pylori. Braz. J. Microbiol. [online]. 2008, vol.39, n.2, pp.238-240. ISSN 1517-8382.

The aim of the present study was to evaluate qualitative changes in the glycoconjugate expression in human gastric tissue of positive and negative patients for Helicobacter pylori, through lectins: Wheat Germ Agglutinin (WGA) and Concanavalin A (Con A). The lectins recognized differently the glycoconjugates in the superficial mucous layer at the gastric tissues. The results suggest a significant change in the carbohydrate moieties present on the surface of the gastric cells during infection.

Keywords : Lectin; gastric mucosae; Helicobacter pylori.
