Evidence has recently been accumulating that domestic animals may play an ancillary role in rickettsial zoonoses. In particular, attention has been focused on the activity of Rickettsia prowazekii in Egyptian and Ethiopian livestock and their ticks. An attempt has now been made to confirm previous findings of R. prowazekii in the sera of zebus, sheep and goats in Ethiopia, which brought epidemic typhus into the category of a zoonosis. This attempt was not successful, but tests did indicate that some ticks were infected with R. conori (boutonneuse fever or tick-borne typhus) and Coxiella burneti (Q fever), this being the first evidence for the existence of these agents in Ethiopia.Antibodies against R. conori were found in significant numbers in the sera of sheep and goats from one locality, but Q-fever antibodies were surprisingly rare.
最近越来越多的证据表明，家畜可能在立克次氏体人畜共患病中起辅助作用。特别是，人们的注意力集中在埃及和埃塞俄比亚家畜及其蜱虫中普氏立克次体的活动上。现在有人试图证实之前在埃塞俄比亚瘤牛、绵羊和山羊血清中发现普氏立克次体的结果，这使得流行性斑疹伤寒被归入人畜共患病类别。这次尝试没有成功，但检测确实表明，一些蜱虫感染了康氏立克次体（纽扣热或蜱传斑疹伤寒）和贝氏柯克斯体（Q热），这是这些病原体在埃塞俄比亚存在的首个证据。在一个地区的绵羊和山羊血清中发现了大量抗康氏立克次体的抗体，但令人惊讶的是，Q热抗体非常罕见。
