A novel rickettsial agent, 'Candidatus Rickettsia asembonensis' strain NMRCiiT, was isolated from cat fleas, Ctenocephalides felis, from Kenya. Genotypic characterization of the new isolate based on sequence analysis of five rickettsial genes, rrs, gltA, ompA, ompB and sca4, indicated that this isolate clustered with Rickettsia felis URRWXCal2. The degree of nucleotide similarity demonstrated that isolate NMRCiiT belongs within the genus Rickettsia and fulfils the criteria for classification as a representative of a novel species. The name Rickettsia asembonensis sp. nov. is proposed, with NMRCiiT (=DSM 100172T=CDC CRIRC RAS001T=ATCC VR-1827T) as the type strain.
一种新型立克次氏体病原体“类阿森博立克次氏体（Candidatus Rickettsia asembonensis）”菌株NMRCiiT，是从肯尼亚的猫栉首蚤（Ctenocephalides felis）中分离出来的。基于五个立克次氏体基因（rrs、gltA、ompA、ompB和sca4）的序列分析对新分离株进行的基因分型表明，该分离株与猫立克次氏体（Rickettsia felis）URRWXCal2聚类在一起。核苷酸相似程度表明，分离株NMRCiiT属于立克次氏体属，并符合作为一个新物种代表进行分类的标准。现提议将其命名为阿森博立克次氏体（Rickettsia asembonensis）新种，以NMRCiiT（=DSM 100172T=CDC CRIRC RAS001T=ATCC VR-1827T）作为模式菌株。
