Taxonomic studies were performed on 13 clinical isolates (ten of which were epidemiologically related) that had been previously identified as Oerskovia turbata. Comparative phylogenetic analysis, based on 16S rRNA gene sequences, indicated that the isolates are closely related to Cellulosimicrobium cellulans with sequence similarity values ranging from 99.5 to 99.8 %. Chemotaxonomic results (fatty acid profiles and menaquinones) supported the inclusion of these isolates in the genus Cellulosimicrobium. The DNA G+C content was 74.5 mol%. The results of DNA-DNA reassociation, whole-cell sugars (with galactose as the characteristic whole sugar) and phenotypic properties, including antimicrobial resistance, indicated that these isolates are representatives of a novel species of the genus Cellulosimicrobium. The name Cellulosimicrobium funkei sp. nov. is proposed for the novel strains, with strain W6122T (=ATCC BAA-886T = DSM 16025T = CCUG 50705T) as the type strain. The definition of this novel Cellulosimicrobium species will assist in the understanding of the epidemiology and clinical significance of these micro-organisms.
对13株先前鉴定为土氏厄氏菌的临床分离株(其中10株在流行病学上相关)进行了分类学研究。基于16S rRNA基因序列的比较系统发育分析表明,这些分离株与纤维微杆菌密切相关,序列相似性值在99.5%至99.8%之间。化学分类学结果(脂肪酸谱和甲基萘醌)支持将这些分离株归入纤维微杆菌属。DNA G+C含量为74.5 mol%。DNA-DNA重缔合、全细胞糖(以半乳糖为特征性全糖)和表型特征(包括抗菌抗性)的结果表明,这些分离株是纤维微杆菌属一个新物种的代表。提议将新菌株命名为Funkei纤维微杆菌(Cellulosimicrobium funkei sp. nov.),菌株W6122T(=ATCC BAA-886T = DSM 16025T = CCUG 50705T)为模式菌株。这一新的纤维微杆菌物种的定义将有助于理解这些微生物的流行病学和临床意义。
