  1. Antral biopsy specimens, type of gastritis and H. pylori 16S rDNA variable V3 region sequence motif derived from whole genomic amplified gastric biopsy DNA.
  2. a) Gastritis classification according to Sydney system [57].
  3. N: normal gastric mucosa; A: antrum predominant gastritis; P: pangastritis; C: corpus predominant gastritis. 1: mild degree; 2: moderate degree; 3: severe degree. a: atrophy; na: no atrophy.
  4. b) Based on pyrosequencing analysis.
  5. c) The 16S rDNA variable V 3 region sequence motif corresponds to H. pylori "strain A", [GenBank:DQ059082] (Fig. 2, group III).
  6. d) The 16S rDNA variable V 3 region sequence motif corresponds to a H. pylori 26695/J99-like combination of H. pylori 26695 and J99 (Fig. 2, group IV).
