小反刍兽疫（PPR）是一种发生在非洲、中东和亚洲的山羊和绵羊的病毒性疾病，对生计和牲畜贸易产生严重影响。许多野生偶蹄动物易受PPR病毒（PPRV）感染，一些爆发已威胁到濒危野生种群。野生物种在PPRV流行病学中的作用尚不清楚，这是控制和根除PPR全球战略的知识空白。这些研究旨在调查肯尼亚和坦桑尼亚大塞伦盖蒂和安博塞利生态系统中野生偶蹄动物的PPRV感染情况。在2015-2016年有目的地采样的132只动物中，通过ID Screen PPR竞争酶联免疫吸附试验（cELISA; IDvet，法国）检测，19.7%的动物为PPRV血清阳性，这些动物来自以下物种：非洲布法罗、角马、topi、孔戈尼、格兰特瞪羚、黑斑羚、汤姆森瞪羚、疣猪和Gerenuk，而水羚和小捻角羚为血清阴性。2018-2019年，对随机选择的非洲布法罗和格兰特瞪羚群进行了横断面调查。191头非洲布法罗和139头瞪羚的PPRV血清阳性率加权估计值分别为12.0%和1.1%。通过PPRV实时逆转录-聚合酶链反应（RT-qPCR），所有眼和鼻拭子和粪便均为阴性。通过快速检测试验和/或RT-qPCR，对绵羊和山羊中的PPR样疾病的调查证实了该地区的PPRV循环。这些结果表明，在这个生态系统中，PPRV在国内小反刍动物中流行的野生动物-牲畜界面的野生偶蹄动物种中存在PPRV感染的血清学证据。暴露于PPRV可能是通过受感染的小反刍动物或野生动物之间的传播，而相对较低的血清阳性率表明持续传播是不可能的。在这个生态系统中的其他主要野生偶蹄动物，如黑斑羚，汤姆森的瞪羚和角马的进一步研究是必要的。
Peste des petits ruminants (PPR) is a viral disease of goats and sheep that occurs in Africa, the Middle East and Asia with a severe impact on livelihoods and livestock trade. Many wild artiodactyls are susceptible to PPR virus (PPRV) infection, and some outbreaks have threatened endangered wild populations. The role of wild species in PPRV epidemiology is unclear, which is a knowledge gap for the Global Strategy for the Control and Eradication of PPR. These studies aimed to investigate PPRV infection in wild artiodactyls in the Greater Serengeti and Amboseli ecosystems of Kenya and Tanzania. Out of 132 animals purposively sampled in 2015–2016, 19.7% were PPRV seropositive by ID Screen PPR competition enzyme-linked immunosorbent assay (cELISA; IDvet, France) from the following species: African buffalo, wildebeest, topi, kongoni, Grant’s gazelle, impala, Thomson’s gazelle, warthog and gerenuk, while waterbuck and lesser kudu were seronegative. In 2018–2019, a cross-sectional survey of randomly selected African buffalo and Grant’s gazelle herds was conducted. The weighted estimate of PPRV seroprevalence was 12.0% out of 191 African buffalo and 1.1% out of 139 Grant’s gazelles. All ocular and nasal swabs and faeces were negative by PPRV real-time reverse transcription-polymerase chain reaction (RT-qPCR). Investigations of a PPR-like disease in sheep and goats confirmed PPRV circulation in the area by rapid detection test and/or RT-qPCR. These results demonstrated serological evidence of PPRV infection in wild artiodactyl species at the wildlife–livestock interface in this ecosystem where PPRV is endemic in domestic small ruminants. Exposure to PPRV could be via spillover from infected small ruminants or from transmission between wild animals, while the relatively low seroprevalence suggests that sustained transmission is unlikely. Further studies of other major wild artiodactyls in this ecosystem are required, such as impala, Thomson’s gazelle and wildebeest.
