Rickettsia felis was first recognised two decades ago and has now been described as endemic to all continents except Antarctica. The rickettsiosis caused by R. felis is known as flea-borne spotted fever or cat-flea typhus. The large number of arthropod species found to harbour R. felis and that may act as potential vectors support the view that it is a pan-global microbe. The main arthropod reservoir and vector is the cat flea, Ctenocephalides felis, yet more than 20 other species of fleas, ticks, and mites species have been reported to harbour R. felis. Few bacterial pathogens of humans have been found associated with such a diverse range of invertebrates. With the projected increase in global temperature over the next century, there is concern that changes to the ecology and distribution of R. felis vectors may adversely impact public health.
猫立克次体于二十年前首次被发现，目前已被描述为除南极洲外各大洲的地方性病菌。由猫立克次体引起的立克次体病被称为蚤传斑点热或猫蚤斑疹伤寒。大量被发现携带猫立克次体且可能充当潜在传播媒介的节肢动物物种，支持了它是一种全球微生物的观点。主要的节肢动物宿主和传播媒介是猫蚤，即猫栉首蚤，但据报道还有20多种其他跳蚤、蜱虫和螨虫物种也携带猫立克次体。很少有人类细菌病原体与如此多样的无脊椎动物有关。鉴于预计下个世纪全球气温会上升，人们担心猫立克次体传播媒介的生态和分布变化可能会对公众健康产生不利影响。
