title: Genetics of Treponema: characterization of Treponema hyodysenteriae and its relationship to Treponema pallidum.
abstract: Saturation reassociation assays with 125I-labeled treponemal DNAs show that Treponema hyodysenteriae is genetically unrelated to T. pallidum (Nichols), T. phagedenis biotype Reiter, and T. refringens biotype Noguchi. Pathogenic and nonpathogenic isolates of T. hyodysenteriae exhibited 28% sequence homology and had an extremely low guanine-plus-cytosine content (25.8%).
