Peste des petits ruminants (PPR) is a vaccine-preventable transboundary animal disease of goats and sheep majorly, and is regarded as a major constraint to small ruminant production especially in developing countries like Nigeria. Despite different strategies that have been employed to control PPR in Nigeria, cases of the disease are still reported in PPR-vaccinated and unvaccinated small ruminant farms. In this study, molecular detection of field PPR virus (PPRV) strains was carried out to determine the presence of PPRV. A total of 135 samples (45 oculo-nasal swabs and 90 tissue samples) were purposively collected between August and October 2020 from goats and sheep at the Akinyele live small ruminant market and at Akinyele and Amosun abattoirs in Ibadan, Oyo State, Nigeria. Using reverse transcriptasepolymerase chain reaction with primers targeting the partial N-gene of PPRV, 10 out of the 135 (7.4%) field samples yielded positive results. The results of this study reveal that PPRV currently circulates in Ibadan. These findings underscore the need for continuous PPR surveillance, more extensive characterization of circulating PPRV strains and the importance of consistent use of quality vaccines in the country to achieve more effective preventive and control strategies against the disease.
小反刍兽疫(PPR)是一种主要影响山羊和绵羊的可预防的跨境动物疾病,是小反刍动物生产的主要制约因素,特别是在尼日利亚等发展中国家。尽管在尼日利亚已经采取了不同的策略来控制 PPR,但在 PPR 疫苗接种和未接种的小反刍动物农场中仍有病例报告。在本研究中,进行了现场 PPR 病毒(PPRV)株的分子检测,以确定 PPRV 的存在。2020 年 8 月至 10 月期间,在尼日利亚奥约州伊巴丹的 Akinyele 活小反刍动物市场和 Akinyele 和 Amosun 屠宰场,从山羊和绵羊中专门采集了 135 份样本(45 份眼鼻拭子和 90 份组织样本)。使用针对 PPRV 部分 N 基因的逆转录聚合酶链反应,135 个现场样本中有 10 个(7.4%)呈阳性结果。本研究的结果表明,PPRV 目前在伊巴丹流行。这些发现强调了需要持续进行 PPR 监测,更广泛地描述循环 PPRV 株的特征,以及在该国持续使用优质疫苗的重要性,以实现更有效的预防和控制策略来对抗该疾病。
