RESUMO
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).
