FIG. 1.

Dendrogram expressing similarity of whole-cell protein patterns of all 22 H. cinaedi isolates and of Helicobacter reference strains. The strain numbers in boldface indicate those strains that were included in DNA-DNA hybridization experiments. The strain marked with an asterisk was originally described as Helicobacter sp. strain Mainz; the strains marked with double asterisks were originally described as “H. westmeadii”.
