Abortion is one of the major threats to the livestock industry, and it also poses significant threats to public health since some of the abortifacient agents are considered zoonotic. (), (), (), and Cache Valley virus (CVV) are recognized as important zoonotic and abortifacient agents of reproductive failure in small ruminants. This study determined the prevalence of these agents in ovine and caprine foetuses in Türkiye. A total of 1 226 foetuses were collected from the sheep (n = 1 144) and goats (n = 82) from different flocks between 2012 and 2017. Molecular detection methods were used to detect , , and DNA and CVV RNA in aborted foetuses. In this study, was the most prevalent abortifacient agent among the investigated ovine (264/1144) and caprine (12/82) foetuses, followed by with a frequency of 2.8% (32/1144) and 8.5% (7/82) in ovine and caprine foetuses, respectively. DNA was detected in 28 (2.4%) and 2 (2.4%) of the ovine and caprine foetuses, respectively. However, CVV RNA was not detected. Although the predominant mixed infection was and , mixed infection of and , and and were also found. The information presented in this study contributes to the understanding of the roles of , , , and CVV in abortions in small ruminants, and could be beneficial for developing more effective control strategies.
流产是畜牧业的主要威胁之一，并且由于一些流产因子被认为是人畜共患病原体，所以它也对公众健康构成重大威胁。（）、（）、（）和卡奇谷病毒（CVV）被认为是小反刍动物繁殖失败的重要人畜共患病原体和流产因子。本研究确定了这些病原体在土耳其绵羊和山羊胎儿中的流行情况。2012年至2017年间，从不同羊群的绵羊（n = 1144）和山羊（n = 82）中总共采集了1226个胎儿。采用分子检测方法检测流产胎儿中的（）、（）和（）DNA以及CVV RNA。在本研究中，在所调查的绵羊（264/1144）和山羊（12/82）胎儿中，（）是最常见的流产因子，其次是（），在绵羊和山羊胎儿中的检出率分别为2.8%（32/1144）和8.5%（7/82）。分别在28个（2.4%）绵羊胎儿和2个（2.4%）山羊胎儿中检测到（）DNA。然而，未检测到CVV RNA。虽然主要的混合感染是（）和（），但也发现了（）和（）、（）和（）的混合感染。本研究提供的信息有助于了解（）、（）、（）和CVV在小反刍动物流产中的作用，并且可能有助于制定更有效的控制策略。
