A Cultured Strain of "<i>Helicobacter heilmannii</i>," a Human Gastric Pathogen, Identified as <i>H. bizzozeronii</i>: Evidence for Zoonotic Potential of <i>Helicobacter</i>

Abstract

We compared the characteristics of a cultured human "Helicobacter heilmannii" isolate with those of other helicobacters found in animals. Phenotypic, protein profile, 16S rDNA sequence, and DNA-DNA hybridization analyses identified the human strain as H. bizzozeronii, a species frequently found in dogs. Thus, H. bizzozeronii may have zoonotic potential.
