来自野生动物宿主的病毒跨物种传播对人类和动物健康构成显着威胁。蝙蝠被认为是新兴病毒最重要的宿主之一,起源于蝙蝠的冠状病毒通过中间宿主传播给人类,导致了影响深远的人畜共患病、严重急性呼吸综合征 (SARS)、、、、、、、、-。在这里,我们提供了病毒学、流行病学、进化和实验证据,证明一种与 HKU2 相关的新型蝙蝠冠状病毒,即猪急性腹泻综合征冠状病毒 (SADS-CoV),是导致中国猪场大规模爆发致命疾病的病原体,该疾病已导致四个农场的 24,693 头仔猪死亡。值得注意的是,疫情始于SARS大流行起源地附近的广东省。此外,我们在 2013 年至 2016 年期间从广东省蝙蝠身上收集的 9.8%(591 份中的 58 份)肛门拭子中发现了 SADS 相关 CoV 的序列同一性为 96-98%,其中主要是菊头蝠(Rhinolophusspp.),它们是已知的 SARS 相关 CoV 的宿主。我们发现 SADS 和 SARS 疫情在地理、时间、生态和病因学方面存在惊人的相似之处。这项研究强调了确定冠状病毒在蝙蝠中的多样性和分布的重要性,以减轻未来可能威胁牲畜、公共卫生和经济增长的疫情爆发。
Cross-species transmission of viruses from wildlife animal reservoirs poses a marked threat to human and animal health. Bats have been recognized as one of the most important reservoirs for emerging viruses and the transmission of a coronavirus that originated in bats to humans via intermediate hosts was responsible for the high-impact emerging zoonosis, severe acute respiratory syndrome (SARS), , , , , , , –. Here we provide virological, epidemiological, evolutionary and experimental evidence that a novel HKU2-related bat coronavirus, swine acute diarrhoea syndrome coronavirus (SADS-CoV), is the aetiological agent that was responsible for a large-scale outbreak of fatal disease in pigs in China that has caused the death of 24,693 piglets across four farms. Notably, the outbreak began in Guangdong province in the vicinity of the origin of the SARS pandemic. Furthermore, we identified SADS-related CoVs with 96–98% sequence identity in 9.8% (58 out of 591) of anal swabs collected from bats in Guangdong province during 2013–2016, predominantly in horseshoe bats (Rhinolophusspp.) that are known reservoirs of SARS-related CoVs. We found that there were striking similarities between the SADS and SARS outbreaks in geographical, temporal, ecological and aetiological settings. This study highlights the importance of identifying coronavirus diversity and distribution in bats to mitigate future outbreaks that could threaten livestock, public health and economic growth.
