Three Gram-stain-positive, irregular-rod-shaped, non-motile, non-spore-forming bacteria were isolated from nematodes collected from Santa Antao, Cabo Verde (CBX151T, CBX152T) and Kakegawa, Japan (CBX130T). Based on 16S rRNA gene sequence similarity, strains CBX130T, CBX151T and CBX152T were shown to belong to the genus Leucobacter. This affiliation was supported by chemotaxonomic data (2,4-diaminobutyric acid in the cell wall; major respiratory quinones MK-10 and MK-11; major polar lipids phosphatidylglycerol and diphosphatidylglycerol; major fatty acids anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0). Strains CBX130T and CBX152T were found to share salient characteristics. Based on morphological, physiological, chemotaxonomic and biochemical analysis, strain CBX152T represents a novel species of the genus Leucobacter, for which the name Leucobacter musarum sp. nov. (type strain CBX152T = DSM 27160T = CIP 110721T) is proposed. Two subspecies of Leucobacter musarum sp. nov. are proposed: Leucobacter musarum sp. nov. subsp. musarum subsp. nov. (type strain CBX152T = DSM 27160T = CIP 110721T) and Leucobacter musarum sp. nov. subsp. japonicus subsp. nov. (type strain CBX130T = DSM 27158T = CIP 110719T). The third novel strain, CBX151T, showed genetic similarities with Leucobacter celer NAL101T indicating that these strains belong to the same species. Based on morphological, physiological, chemotaxonomic and biochemical differences it is proposed to split the species Leucobacter celer into two novel subspecies, Leucobacter celer subsp. celer subsp. nov. (type strain NAL101T = KACC 14220T = JCM 16465T) and Leucobacter celer subsp. astrifaciens subsp. nov. (type strain CBX151T = DSM 27159T = CIP 110720T), and to emend the description of Leucobacter celerShin et al. 2011.
从佛得角圣安唐岛（CBX151T、CBX152T）和日本挂川市（CBX130T）采集的线虫中分离出三株革兰氏阳性、不规则杆状、无运动性、不形成芽孢的细菌。基于16S rRNA基因序列相似性，菌株CBX130T、CBX151T和CBX152T被证明属于勒克氏菌属。细胞壁中的2,4 - 二氨基丁酸、主要呼吸醌MK - 10和MK - 11、主要极性脂质磷脂酰甘油和双磷脂酰甘油、主要脂肪酸anteiso - C15 : 0、anteiso - C17 : 0和iso - C16 : 0等化学分类学数据支持了这种分类关系。发现菌株CBX130T和CBX152T具有显著特征。基于形态学、生理学、化学分类学和生化分析，菌株CBX152T代表勒克氏菌属的一个新物种，为此提出名称为勒克氏菌新种（Leucobacter musarum sp. nov.）（模式菌株CBX152T = DSM 27160T = CIP 110721T）。提出了勒克氏菌新种的两个亚种：勒克氏菌新种亚种musarum subsp. nov.（模式菌株CBX152T = DSM 27160T = CIP 110721T）和勒克氏菌新种亚种japonicus subsp. nov.（模式菌株CBX130T = DSM 27158T = CIP 110719T）。第三株新菌株CBX151T与勒克氏菌（Leucobacter celer）NAL101T显示出遗传相似性，表明这些菌株属于同一物种。基于形态学、生理学、化学分类学和生化差异，建议将勒克氏菌（Leucobacter celer）分为两个新亚种，勒克氏菌celer亚种celer subsp. nov.（模式菌株NAL101T = KACC 14220T = JCM 16465T）和勒克氏菌celer亚种astrifaciens subsp. nov.（模式菌株CBX151T = DSM 27159T = CIP 110720T），并修订勒克氏菌（Leucobacter celer）Shin等人2011年的描述。
