Strain AUS118 was isolated from an Argas lagenoplastis tick collected from the nest of a Petrochelidon ariel (fairy martin) in Australia in 2013. Microscopic observation of infected cell cultures indicated this strain had a morphology and intracellular location typical of Rickettsiaspecies. Phylogenetic analysis of this strain based firstly on multi-locus sequence analysis and subsequently on whole genome analysis demonstrated that AUS118 was most closely related to, but divergent from Rickettsia japonica and Rickettsia heilongjiangensis. We therefore propose the creation of a novel species, Rickettsia fournieri sp. nov, with the type strain AUS118 (DSM 28985 and CSUR R501).
菌株AUS118于2013年从澳大利亚一只从白脸燕鸥巢穴采集的拉氏锐缘蜱中分离得到。对受感染细胞培养物的显微镜观察表明,该菌株具有立克次氏体属物种典型的形态和细胞内定位。首先基于多位点序列分析,随后基于全基因组分析对该菌株进行系统发育分析,结果表明AUS118与日本立克次氏体和黑龙江立克次氏体关系最为密切,但又有所不同。因此,我们提议创建一个新物种,即弗氏立克次氏体(Rickettsia fournieri sp. nov),模式菌株为AUS118(DSM 28985和CSUR R501)。
