Livestock markets are considered vital parts of the agricultural economy, particularly in developing countries where livestock keeping contributes to both food security and economic stability. Animals from diverse sources are moved to markets, they mix while they are there and are subsequently redistributed over wide geographic areas. Consequently, markets provide an opportunity for targeted surveillance for circulating pathogens. This study investigated the use of environmental sampling at a live goat market in Nepal for the detection of foot-and-mouth disease virus (FMDV) and peste des petits ruminants virus (PPRV), both of which are endemic. Five visits to the market were carried out between November 2016 and April 2018, with FMDV RNA detected on four visits and PPRV RNA detected on all five visits. Overall, 4.1% of samples (nine out of 217) were positive for FMDV RNA and 60.8% (132 out of 217) were positive for PPRV RNA, though the proportion of positive samples varied amongst visits. These results demonstrate that non-invasive, environmental sampling methods have the potential to be used to detect circulation of high priority livestock diseases at a live animal market and, hence, to contribute to their surveillance and control.
牲畜市场被认为是农业经济的重要组成部分，特别是在发展中国家，牲畜养殖对粮食安全和经济稳定都有贡献。来自不同来源的动物被运往市场，它们在那里混合，随后被重新分配到广泛的地理区域。因此，市场为有针对性地监测流通中的病原体提供了机会。本研究调查了在尼泊尔一个活山羊市场使用环境采样来检测口蹄疫病毒（FMDV）和小反刍动物瘟病毒（PPRV）的情况，这两种病毒在当地都有流行。在 2016 年 11 月至 2018 年 4 月期间进行了五次市场访问，其中四次访问中检测到 FMDV RNA，五次访问中均检测到 PPRV RNA。总体而言，4.1%的样本（217 个样本中的 9 个）FMDV RNA 检测呈阳性，60.8%（217 个样本中的 132 个）PPRV RNA 检测呈阳性，但阳性样本的比例在各次访问中有所不同。这些结果表明，非侵入性的环境采样方法有可能用于检测活畜市场上高优先级牲畜疾病的传播情况，从而有助于对这些疾病进行监测和控制。
