从产真菌白蚁巴氏大白蚁的后肠中分离到一株革兰氏阴性、兼性厌氧、非游动、球状至短杆状细菌，定名为Dys-CH1(T)。菌株Dys-CH1(T)的最适pH为7.2~7.6，最适培养温度为35~37℃。16S rRNA基因序列分析表明，Dys-CH1(T)与CapnocytophagoidesJCM 16697(T)和Dysgonomonas gadei CCUG 42882(T)的相似性分别为94.6%和90.9%。Dys-CH1(T)菌株在重要的分类特征，包括生境、生化测试、DNA G+C含量、胆汁抗性、脂肪酸组成和对抗菌剂的敏感性等方面，被发现不同于已公布有效名称的Dysgonomonas属其他物种。根据这些特征，菌株Dys-CH1(T)是大白蚁属Dysgonomonas的一个新种，命名为大白蚁Dysgonomonas acrotermitis sp.11月是提议的。模式菌株为Dys-CH1(T)(=JCM 19375(T)=Dsm 27370(T))。
A Gram-stain-negative, facultatively anaerobic, non-motile and coccoid- to short-rod-shaped bacterium, designated strain Dys-CH1(T), was isolated from the hindgut of a fungus-growing termite Macrotermes barneyi. The optimal pH and cultivation temperature of strain Dys-CH1(T) were pH 7.2-7.6 and 35-37 °C, respectively. Sequence analysis of 16S rRNA gene showed that Dys-CH1(T) shared 94.6 % and 90.9 % similarity with Dysgonomonas capnocytophagoides JCM 16697(T) and Dysgonomonas gadei CCUG 42882(T), respectively. Strain Dys-CH1(T) was found to be different from other species of the genus Dysgonomonas with validly published names with respect to taxonomically important traits, including habitat, biochemical tests, DNA G+C content, bile resistance, fatty-acid composition and susceptibility to antimicrobial agents. On the basis of these characteristics, strain Dys-CH1(T) represents a novel species of the genus Dysgonomonas for which the name Dysgonomonas macrotermitis sp. nov. is proposed. The type strain is Dys-CH1(T) ( = JCM 19375(T) = DSM 27370(T)).
