Ruminants play an important role in economic sustenance in many developing countries. Abortion is one of the most important causes of economic losses in sheep livestock and, for this reason, it is very important to know, at an early stage, which pathogens caused abortion.
The aim of the study is to obtain data about the distribution of abortifacient pathogens in the Italian regions of Latium and Tuscany, the awareness of the distribution of infectious agents causing abortion could allow the development of an appropriate vaccination and prophylaxis plan, to avoid major economic losses.
388 abortions were collected during the 2015-2018 period. Organs, tissues, and swabs were subjected to DNA extraction and then analyzed with commercial q-PCR kits for the detection of the most common abortion pathogens circulating in these geographical areas.
The positivity in 148 abortions was 56% for , 14% for , 16% for spp, 12% for and 2% for . Interesting results were obtained for cases of abortions with co-infection of abortion pathogens.
Diagnosing the cause of abortion remains a multifaceted process that may also include non-infectious factors such as deficiencies and toxicities. Further research is needed also to assess the role of low pathogen concentrations and co-infections in the abortions of sheep.
反刍动物在许多发展中国家的经济维持中起着重要作用。流产是绵羊养殖业经济损失的最重要原因之一，因此，早期了解哪些病原体引起流产非常重要。
本研究的目的是获得关于意大利拉齐奥和托斯卡纳地区致流产病原体分布的数据。对引起流产的传染性病原体分布的认识可以制定适当的疫苗接种和预防计划，以避免重大的经济损失。
在 2015 年至 2018 年期间收集了 388 例流产。对器官、组织和拭子进行 DNA 提取，然后用商业 q-PCR 试剂盒分析，以检测这些地理区域中常见的流产病原体。
148 例流产中阳性率为：56%为 ，14%为 ，16%为 spp，12%为 ，2%为 。对于流产病原体合并感染的病例，获得了有趣的结果。
诊断流产的原因仍然是一个多方面的过程，也可能包括非传染性因素，如缺乏和毒性。还需要进一步研究，以评估低病原体浓度和合并感染在绵羊流产中的作用。
