A Gram-negative, coccobacillus-shaped, aerobic bacterium, designated strain UST040201-002T, was isolated in February 2004 from seawater at the outlet of a sandfilter in Port Shelter, Hong Kong SAR, China. This strain possessed ubiquinone-8; its 16S rRNA gene sequence shared only 91% similarity with the sequence from Caedibacter taeniospiralis and 89-90% similarity with sequences from Francisella tularensis, Francisella novicida, Francisella philomiragia and Wolbachia persica. 16S rRNA gene sequence analysis showed that the strain formed a distinct clade with C. taeniospiralis. This subcluster formed a tight coherent group with members of the family Francisellaceae and W. persica. Combined phylogenetic and physiological data suggest that strain UST040201-002T represents a novel genus and species within the order Tauhiotrichales. The name Fangia hongkongensis gen. nov., sp. nov. is proposed; the type strain is UST040201-002T (=JCM 14605T=NRRL B-41860T).
2004年2月，从中国香港特别行政区牛尾海一个砂滤器出口处的海水中分离出一株革兰氏阴性、球杆菌状、需氧细菌，命名为UST040201-002T。该菌株含有泛醌-8；其16S rRNA基因序列与螺旋带状开氏杆菌（Caedibacter taeniospiralis）的序列相似度仅为91%，与土拉弗朗西斯菌（Francisella tularensis）、新凶手弗朗西斯菌（Francisella novicida）、美人鱼弗朗西斯菌（Francisella philomiragia）和波斯沃巴赫菌（Wolbachia persica）的序列相似度为89-90%。16S rRNA基因序列分析表明，该菌株与螺旋带状开氏杆菌形成一个独特的进化枝。这个亚群与弗朗西斯菌科成员和波斯沃巴赫菌形成一个紧密连贯的类群。系统发育和生理数据综合表明，UST040201-002T菌株代表嗜毛菌目（Tauhiotrichales）中的一个新属和新种。建议命名为香港方氏菌（Fangia hongkongensis），属名新属，种名新种；模式菌株为UST040201-002T（=JCM 14605T=NRRL B-41860T）。
