A reassessment was undertaken of published characteristics of the five species of anaerobic intestinal spirochaetes in the genus Brachyspira (Brachyspira aalborgi, Brachyspira alvinipulli, Brachyspira hyodysenteriae, Brachyspira innocens and Brachyspira pilosicoli) and the two species in the genus Serpulina (Serpulina intermedia and Serpulina murdochii). Comparisons were made of published descriptions, including phenotypic properties, grouping by multilocus enzyme electrophoresis, DNA base composition, DNA-DNA relative reassociation values and 16S rRNA gene sequence similarity. On the basis of extensive similarities between all the species, it is proposed to reclassify Serpulina intermedia Stanton et al. 1997 and Serpulina murdochii Stanton et al. 1997 in the genus Brachyspira, as Brachyspira intermedia comb. nov. (type strain ATCC 51140T) and Brachyspira murdochii comb. nov. (type strain ATCC 51284T).
对短螺旋体属（短螺旋体属的五种厌氧肠道螺旋体，即奥尔堡短螺旋体、阿尔文短螺旋体、猪痢疾短螺旋体、无害短螺旋体和毛样短螺旋体）和蛇形螺旋体属（中间蛇形螺旋体和默多克蛇形螺旋体）已发表的特征进行了重新评估。对已发表的描述进行了比较，包括表型特性、多位点酶电泳分组、DNA碱基组成、DNA-DNA相对重结合值和16S rRNA基因序列相似性。基于所有物种之间的广泛相似性，建议将1997年斯坦顿等人命名的中间蛇形螺旋体和1997年斯坦顿等人命名的默多克蛇形螺旋体重分类到短螺旋体属，分别为中间短螺旋体（新组合，模式菌株ATCC 51140T）和默多克短螺旋体（新组合，模式菌株ATCC 51284T）。
