[comparative genome analysis of helicobacter pylori strains].dna macroarrays were used to characterize 17 helicobacter pylori strains isolated in four geographic regions of russia (moscow, st. petersburg, kazan, and novosibirsk). of all genes, 1272 (81%) proved to occur in all strains and to constitute a functional core of the genome, and 293 (18.7%) were strain-specific and greatly varied among the h. pylori strains. most (71%) of the latter had unknown functions; the remainder included restriction-modification genes (3-9%), transposition genes (2-4%), a ...200312942635
