Several wild animal species have been implicated as hosts of Ehrlichia ruminantium (formerly Cowdria ruminantium), the rickettsial agent causing heartwater, a fatal disease of domestic ruminants in sub-Saharan Africa and eastern Caribbean. However, evidence for infection in most wild species is inconclusive because of inadequate diagnostic techniques. Infection has been proven only in 12 African ruminants, three non-African ruminants and two African rodents. A subclinical carrier state occurs in eight of the African ruminant species. Further studies on E. ruminantium infection in wild animal species are needed in order to determine the host range of this pathogen accurately. The host range of Ehrlichia ruminantium in wildlife is reviewed here and the role played by these species in the epidemiology and spread of heartwater is discussed.
几种野生动物物种被认为是反刍动物埃立克体(以前称为反刍动物考德里氏体)的宿主,这种立克次氏体病原体可导致心水病,这是一种在撒哈拉以南非洲和东加勒比地区影响家养反刍动物的致命疾病。然而,由于诊断技术不足,大多数野生动物物种的感染证据尚无定论。仅在12种非洲反刍动物、3种非非洲反刍动物和2种非洲啮齿动物中证实了感染。8种非洲反刍动物物种存在亚临床携带状态。需要对野生动物物种中的反刍动物埃立克体感染进行进一步研究,以便准确确定该病原体的宿主范围。本文综述了野生动物中反刍动物埃立克体的宿主范围,并讨论了这些物种在心水病流行病学和传播中所起的作用。
