Book (stand-alone)Guidelines for the Control and Prevention of Peste des Petits Ruminants (PPR) in Wildlife Populations
Peste des petits ruminants Global Eradication Programme
2021The PPR Secretariat, the OIE Working Group on Wildlife, and the PPR Global Research and Expertise Network (GREN) have jointly developed these guidelines for PPR prevention, outbreak response, and control in wildlife, which can be used by countries to develop their PPR national strategic plans. These guidelines are intended to help countries in the development and implementation of PPR eradication programmes, including objectives, policies and strategies that can be adapted to the full range of national needs, and that facilitate the integration of the wildlife sector into the national strategic plan. Integration will enhance the conservation of wildlife populations, and facilitate management of diseases at the wildlife–livestock interface. Establishing a multisectoral coordination mechanism is essential to ensure good governance and effective collaboration in achieving PPR eradication goals. The purpose of this document is to provide a conceptual framework that can be tailored to a particular national and epidemiological context. In addition, these guidelines, while specific to PPR eradication, can be adapted for any disease at the wildlife–human–livestock interface. -
ArticlePeste des Petits Ruminants Virus Infection at the Wildlife–Livestock Interface in the Greater Serengeti Ecosystem, 2015–2019 2021
Also available in:
No results found.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.
