In 12 biopsies of his remarkably well - preserved gut tissue (and stomach contents), they were able to
isolate enough bacterial DNA to sequence the genome of H.
pylori to relatively high resolution, as they report online today in Science.
In addition, the team found that H.
pylori populations become more
isolated as they move farther from East Africa, differing less genetically within the population, but more compared with East African populationsa finding that also held for human DNA.
The researchers
isolated two related but genetically diverse strains of H.
pylori from a 90 - year - old patient with gastric ulcer disease.
It turned out that doctors had
isolated H.
pylori from Wilson's stomach during his initial visit, and a few years later, researchers in Cambridge, Massachusetts, sequenced his organism.
