"Candidatus Rickettsia asemboensis" is an obligate intracellular bacterium of the Rickettsiales order, genetically related to species belonging to the Rickettsia felis group, agents of flea-borne spotted fever. Here we report for the first time the detection of "Ca. R. asemboensis", a flea-associated organism, in Rhipicephalus sanguineus ticks. It is the first occurrence of this emerging bacterium in Brazil, which increases the geographical distribution of this R. felis-like agent.
“类阿散波立克次氏体（Candidatus Rickettsia asemboensis）”是立克次氏体目下的一种专性细胞内细菌，在基因上与属于猫立克次氏体组的物种相关，猫立克次氏体组是蚤传斑点热的病原体。在此，我们首次报告在血红扇头蜱中检测到与蚤相关的“类阿散波立克次氏体”。这是这种新出现的细菌在巴西的首次出现，扩大了这种类猫立克次氏体病原体的地理分布范围。
