The taxonomic position of an actinomycete, strain 1BDZ(T), isolated from a clinical human source was determined using a polyphasic approach. Phylogenetic analysis based on almost complete 16S rDNA sequences showed that this organism consistently formed a distinct line with the Amycolatopsis methanolica subclade within the genus Amycolatopsis, and shared moderately low 16S rDNA similarity (<96.5 %) with other species. The organism was also found to have chemical and morphological properties typical of members of the genus Amycolatopsis. A range of phenotypic characteristics readily distinguished this strain from representatives of all species of Amycolatopsis with validly published names. On the basis of these data, a novel species, Amycolatopsis palatopharyngis sp. nov., is proposed to accommodate strain 1BDZ(T) (=AS 4.1729(T)=PCM 2600(T)).
采用多相分类法确定了从人类临床样本中分离出的一株放线菌菌株1BDZ(T)的分类地位。基于几乎完整的16S rDNA序列的系统发育分析表明，该菌株始终与拟无枝酸菌属内的甲醇拟无枝酸菌亚分支形成一个独特的分支，并且与其他物种的16S rDNA相似性中等偏低（<96.5%）。还发现该菌株具有拟无枝酸菌属成员典型的化学和形态学特性。一系列表型特征使该菌株很容易与所有已有效发表名称的拟无枝酸菌属物种的代表区分开来。基于这些数据，提出了一个新物种——腭咽拟无枝酸菌（Amycolatopsis palatopharyngis sp. nov.），以容纳菌株1BDZ(T)（=AS 4.1729(T)=PCM 2600(T)）。
