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%).
用125I标记的密螺旋体DNA进行的饱和重缔合分析表明,猪痢疾密螺旋体在遗传上与梅毒密螺旋体(Nichols株)、溃蚀性密螺旋体生物型Reiter以及屈折密螺旋体生物型Noguchi无关。猪痢疾密螺旋体的致病性和非致病性分离株显示出28%的序列同源性,并且鸟嘌呤加胞嘧啶含量极低(25.8%)。
