摘要

有证据表明,包括宠物在内的许多动物物种都曾接触过大流行性 SARS-CoV-2 病毒,因为宠物与主人关系密切,容易接触到这种病毒。人们认为,狗对这种病毒的易感性很低,感染后会发生血清转换,而不是脱落,这可能通过与受感染的主人直接接触或通过环境污染间接发生。本研究评估了意大利南部坎帕尼亚大区表面健康的狩猎犬和流浪犬(采样时间为 2023 年 9 月)的 SARS-CoV-2 血清流行率。使用两种不同的商业 ELISA,共有 5/112 只(4.5%)动物的血清检测呈阳性。与猎犬相比,流浪动物的接触率更高。对每只动物的粪便和血液都进行了针对核壳和 ORF1ab 编码序列的实时 PCR 检测。没有动物在分子调查中检测出阳性,这表明动物在采样时并未受到活动性感染。

SARS-CoV-2 exposure in hunting and stray dogs of southern Italy.

Evidence of exposure to the pandemic SARS-CoV-2 has been described in numerous animal species, including pets, which are predisposed to coming into contact with this virus due to their close relationship with owners. It has been accepted that dogs are poorly susceptible to this virus and that seroconversion, rather than shedding, occurs following infection, which can occur directly through contact with infected owners or indirectly through environmental contamination. In this study, the seroprevalence of SARS-CoV-2 was evaluated in apparently health hunting and stray dogs of Campania region, southern Italy (sampled in September 2023). A total of 5/112 (4.5%) animals tested seropositive using two different commercial ELISAs. Stray animals had greater exposure than hunting dogs. The feces and blood of each animal were tested with a real-time PCR targeting the nucleocapsid and ORF1ab coding sequences. No animal tested positive in molecular investigations, indicating a past exposure without active infection at the time of sampling.

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.
