intact cag pathogenicity island of helicobacter pylori without disease association in kolkata, india.several genes including the caga in the cag pathogenicity island (cag pai) of helicobacter pylori are thought to be associated with the gastroduodenal diseases and hence variation in the genetic structure of the cag pai might be responsible for different clinical outcomes. our study was undertaken to characterize the cag pai of h. pylori strains from duodenal ulcer (du) patients and asymptomatic or non-ulcer dyspepsia (nud/av) subjects from kolkata, india. strains isolated from 52 individuals (3 ...201021195664
virulence genes and neutral dna markers of helicobacter pylori isolates from different ethnic communities of west bengal, india.virulence-associated genes and neutral dna markers of helicobacter pylori strains from the santhal and oroan ethnic minorities of west bengal, india, were studied. these people have traditionally been quite separate from other indians and differ culturally, genetically, and linguistically from mainstream bengalis, whose h. pylori strains have been characterized previously. h. pylori was found in each of 49 study participants, although none had peptic ulcer disease, and was cultured from 31 of th ...200312904384
virulence genes in helicobacter pylori strains from west bengal residents with overt h. pylori-associated disease and healthy volunteers.we compared putative molecular markers of virulence (vaca, caga, and icea) of helicobacter pylori strains isolated from 52 adult duodenal ulcer patients from west bengal, india, with those of h. pylori strains isolated from 48 adult healthy volunteers from the same region. on the basis of genotyping by pcr, we conclude that the h. pylori strains isolated from the two study groups were indistinguishable and that there are geographic variations in the association of certain putative h. pylori viru ...200212089290
