Abstract

Coronaviruses (CoVs) are a diverse group of RNA viruses that affect both human and animal health. Swine populations are particularly relevant in the ecology of CoVs, acting as potential intermediate hosts for zoonotic transmission. This study aimed to assess the occurrence of CoVs in farmed pigs in Portugal and Spain. A total of 400 fecal samples were collected from pigs in northern Portugal and northern Spain and screened using a broad-spectrum pan-CoV nested RT-PCR assay. Of these, 18 samples (4.5%) tested positive for CoV, and phylogenetic analyses confirmed their classification within the Alphacoronavirus genus. The detected sequences shared high nucleotide identity with bat-associated Alphacoronaviruses from Portugal, Spain, Italy, and the United Kingdom, emphasizing the importance of continued research on the role of bats in the transmission cycle and the zoonotic potential of Alphacoronaviruses. These findings highlight the importance of ongoing surveillance in swine populations to monitor emerging CoV strains and assess potential zoonotic risks.

在伊比利亚半岛的猪身上发现的与蝙蝠相关的冠状病毒：对潜在跨物种传播的见解

冠状病毒是一组影响人类和动物健康的多种RNA病毒。猪群在冠状病毒的生态学中尤为重要，它们是人畜共患病传播的潜在中间宿主。本研究旨在评估葡萄牙和西班牙养殖猪中冠状病毒的发生情况。从葡萄牙北部和西班牙北部共收集了400份猪粪便样本，并使用广谱泛冠状病毒巢式RT-PCR法进行筛选。其中18个样本（4.5%）的冠状病毒检测呈阳性，系统发育分析证实它们属于甲型冠状病毒属。检测到的序列与来自葡萄牙、西班牙、意大利和英国的蝙蝠相关的甲型冠状病毒具有高核苷酸同源性，这强调了继续研究蝙蝠在传播周期中的作用和甲型冠状病毒的人畜共患潜力的重要性。这些发现强调了对猪群进行持续监测以监测新出现的冠状病毒毒株和评估潜在人畜共患风险的重要性。

期刊介绍： Veterinary Research Communications publishes fully refereed research articles and topical reviews on all aspects of the veterinary sciences. Interdisciplinary articles are particularly encouraged, as are well argued reviews, even if they are somewhat controversial. The journal is an appropriate medium in which to publish new methods, newly described diseases and new pathological findings, as these are applied to animals. The material should be of international rather than local interest. As it deliberately seeks a wide coverage, Veterinary Research Communications provides its readers with a means of keeping abreast of current developments in the entire field of veterinary science.
