During a case-control study on severe acute malnutrition, strain Marseille-Q1233 was isolated. It is a Gram-positive, rod-shaped and halophilic bacillus isolated from a stool sample of Malian child under the age of 5. The fatty acid profile of the strain consisted of C15:0-anteiso and C14:0-iso as major components. Digital DNA-DNA hybridization and average nucleotide identity calculation showed 23.10% and 80.81% similarity respectively between strain Marseille-Q1233 and strain Marseille-P2607, the phylogenetically closely related species with standing in nomenclature. On the basis of these results, we report the description of sp. nov. strain Marseille-Q1233 as a new bacterial species.
在一项关于重度急性营养不良的病例对照研究中,分离出了马赛-Q1233菌株。它是一种革兰氏阳性、杆状且嗜盐的芽孢杆菌,从一名5岁以下马里儿童的粪便样本中分离得到。该菌株的脂肪酸谱以C15:0-anteiso和C14:0-iso为主要成分。数字DNA-DNA杂交和平均核苷酸同一性计算表明,马赛-Q1233菌株与在命名上有亲缘关系的马赛-P2607菌株之间的相似性分别为23.10%和80.81%。基于这些结果,我们报告了新物种马赛-Q1233菌株的描述。
