立克次体的许多物种是众所周知的哺乳动物病原体，由吸血节肢动物传播。然而，分子调查不断发现新的立克次体物种，通常在意想不到的宿主中，包括许多不以血液为食的节肢动物。本研究报告了一个系统的分子特征的立克次体感染psodLiposcelisbostrychophila（Psocoptera：Liposcelidae），一个常见的和世界性的家庭害虫。令人惊讶的是，psod立克次体被证明是猫立克次体，一种由跳蚤传播的人类病原体，导致严重的发病率和偶尔的死亡率。从psocid R. felis的序列测定结果与R. felis猫from fleas跳蚤.由于Liposcelis昆虫通常与人类和其他脊椎动物密切相关，因此推测它们获得了R。felis猫from fleas跳蚤. R.猫在psods导致脊椎动物的疾病是未知的，值得进一步研究。
Many species of Rickettsia are well-known mammalian pathogens transmitted by blood-feeding arthropods. However, molecular surveys are continually uncovering novel Rickettsia species, often in unexpected hosts, including many arthropods that do not feed on blood. This study reports a systematic molecular characterization of a Rickettsia infecting the psocid Liposcelis bostrychophila (Psocoptera: Liposcelidae), a common and cosmopolitan household pest. Surprisingly, the psocid Rickettsia is shown to be Rickettsia felis, a human pathogen transmitted by fleas that causes serious morbidity and occasional mortality. The plasmid from the psocid R. felis was sequenced and was found to be virtually identical to the one in R. felis from fleas. As Liposcelis insects are often intimately associated with humans and other vertebrates, it is speculated that they acquired R. felis from fleas. Whether the R. felis in psocids causes disease in vertebrates is not known and warrants further study.
