Definition
The name “Helicobacter heilmannii” has been used for many years referring to uncultivable, long, spiral-shaped bacteria, morphologically distinct from H. pylori, observed in the stomach of humans and animals. These bacteria were initially designated as “Gastrospirillum hominis” and, based on sequence analysis of the 16S rRNA gene, were provisionally named “Helicobacter heilmannii,” in honor of the German pathologist Konrad Heilmann who first studied the pathology associated with these microorganisms.
“H. heilmannii” was further subdivided into two taxa, as phylogenetic analysis of the 16S rRNA gene revealed two types that differed by more than 3% in their nucleotide sequence: “H. heilmannii” type 1, which are morphologically and genetically identical to H. suis (formerly designated “Gastrospirillum suis”), a species that colonizes the...
