Abstract

We report on a new Actinobaculum species, "Actinobaculum massiliae," isolated from the urine of an elderly woman with recurrent cystitis. Its phenotypic pattern was similar to those of both of the other Actinobaculum species described to date. On 16S rRNA sequencing, the Marseille isolate shared 95% homology with Actinobaculum suis, 92 to 93% homology with Actinobaculum schaalii, 91 to 92% homology with Arcanobacterium spp., and 87 to 90% homology with Actinomyces species. A bootstrap value of 99% supports the node separating the Actinobaculum sp. from its closest neighbor (A. suis). In conclusion, on the basis of phenotypic, genotypic, and phylogenetic assessments, we show that the Marseille isolate is a previously unrecognized organism within the Actinobaculum genus, and we propose placement of the organism in the taxon "Actinobaculum massiliae."

摘要

我们报告了一种新的放线杆菌属物种,“马赛放线杆菌”,它是从一名患有复发性膀胱炎的老年女性尿液中分离出来的。其表型模式与迄今描述的其他两种放线杆菌属物种相似。在16S rRNA测序中,来自马赛的分离株与猪放线杆菌有95%的同源性,与沙氏放线杆菌有92%至93%的同源性,与隐秘杆菌属有91%至92%的同源性,与放线菌属有87%至90%的同源性。99%的自展值支持将该放线杆菌属物种与其最接近的邻居(猪放线杆菌)分开的节点。总之,基于表型、基因型和系统发育评估,我们表明来自马赛的分离株是放线杆菌属内一种先前未被识别的生物体,并且我们建议将该生物体归入“马赛放线杆菌”分类单元。
