The effects of topical administration of genotypically different strains of H pylori on macromolecular leakage from mucosal PCVs. Only strain 60190 induced significant leakage from PCVs at all time points. Strains 60190 vacA::km and J154 only induced significant leakage at five minutes. Distilled water had no significant effect at any time point. Each point represents the means of 18 areas. * p<0.05, **p<0.01 when compared with controls using the Mann-Whitney U test. Results are presented as means (SD).
