直到 2000 年，南美洲只知道三种立克次体： (i) 立克次体，由 Amblyomma cajennense 蜱和 Amblyomma aureolatum 蜱传播，在哥伦比亚、阿根廷和巴西均有报道，是落基山斑疹热的病原体； ㈡ 普瓦泽基立克次体，通过体虱传播，在高原地区（主要是秘鲁）引起流行性斑疹伤寒； (iii) 伤寒立克次体，通过跳蚤传播并在许多国家引起地方性斑疹伤寒。在这个新世纪中，南美洲至少报告了七种其他立克次体：感染跳蚤的猫立克次体和蜱相关病原体帕克里立克次体、马氏立克次体、Candidatus“Rickettsia amblyommii”、Bellii立克次体、Rickettsia rhipicephali和Candidatus“Rickettsia andeanae”。在这些其他立克次体中，只有R.猫科动物、帕克里犬和马西利亚犬目前被认为是人类病原体。立克次体是自然界中一种罕见的病原体，可感染：
Until the year 2000, only three Rickettsia species were known in South America: (i) Rickettsia rickettsii, transmitted by the ticks Amblyomma cajennense, and Amblyomma aureolatum, reported in Colombia, Argentina, and Brazil, where it is the etiological agent of Rocky Mountain spotted fever; (ii) Rickettsia prowazekii, transmitted by body lice and causing epidemic typhus in highland areas, mainly in Peru; (iii) Rickettsia typhi, transmitted by fleas and causing endemic typhus in many countries. During this new century, at least seven other rickettsiae were reported in South America: Rickettsia felis infecting fleas and the tick-associated agents Rickettsia parkeri, Rickettsia massiliae, Candidatus "Rickettsia amblyommii," Rickettsia bellii, Rickettsia rhipicephali, and Candidatus "Rickettsia andeanae. " Among these other rickettsiae, only R. felis, R. parkeri and R. massiliae are currently recognized as human pathogens. R. rickettsii is a rare agent in nature, infecting :
