Abstract

Two isolates of intra-amoeba-growing bacteria, LegA ( = DSM 24804 = CSUR P146) and LegM ( = DSM 24805 = CSUR P145), were characterized on the basis of microscopic appearance, staining characteristics, axenic growth at different temperatures and the sequences of the , , 16S rRNA and genes, as well as the 23S–5S region. Phylogenetic analysis showed that these two isolates lay within the radius of the family . Furthermore, the analysis of these genes yielded congruent data that indicated that, although strain LegM clusters specifically with ATCC 35072 and LegA clusters with ATCC 49596, the divergence observed between these species was greater than that observed between other members of the family. Taken together, these results support the proposal that these two isolates represent novel members of the genus , and we propose to name them sp. nov. for LegM ( = DSM 24805 = CSUR P145) and sp. nov. for LegA ( = DSM 24804 = CSUR P146).
