We determined the 16S rRNA gene sequences of three crustacean "Rickettsiella armadillidii" strains. Rickettsiella bacteria overall appear to form a monophyletic group that diverged from Coxiella bacteria approximately 350 million years ago. Therefore, the genus Rickettsiella as a whole (not just Rickettsiella grylli) should be classified among the Gammaproteobacteria instead of the Alphaproteobacteria.
我们测定了三株甲壳类“犰狳立克次氏体”菌株的16S rRNA基因序列。立克次氏体细菌总体上似乎形成了一个单系群,大约在3.5亿年前从柯克斯氏体细菌分化而来。因此,整个立克次氏体属(不仅仅是蟋蟀立克次氏体)应归类于γ-变形菌纲,而不是α-变形菌纲。
