摘要

天体病毒是孵化场管理中新出现的一种危害，给全球家禽养殖场造成了巨大的经济损失。鸡天体病毒（CAstV）和禽肾炎病毒（ANV）会导致孵化率下降，主要原因是胚胎死亡、雏鸡面色苍白和流鼻涕，无力孵化。孵化病是通过蛋直接感染或垂直传播发生的。然而，星状病毒在这些疾病中的具体作用在很大程度上仍不为人所知。为了弄清这个问题，我们根据鸡场的临床症状和种鸡场的阿斯特罗病毒血清学阳性结果，选择了意大利皮埃蒙特的一家优质孵化场。对从孵化场到养殖场的病毒动态进行了跟踪。通过评估环境和动物样本中的病毒载量来监测 CAstV 和 ANV 的存在。有趣的是，在孵化第 18 天的雏鸡卵黄囊和孵化 1 天的雏鸡肠道内容物中都检测到了这两种病毒，而孵化场环境样本、鸡蛋表面和胚胎肠道内容物中的病毒均为阴性。在孵化场的动物组织中，CAstV 的拷贝数较高，而在养殖场的动物组织中则检测到较高的 ANV 负荷。此外，我们的数据还表明，这两种病毒均可垂直传播。在孵化场和养殖场的样本中还发现了频繁的混合感染。最后，我们首次在意大利获得了 ANV 的全长基因组和分子特征。

期刊介绍： Avian Pathology is the official journal of the World Veterinary Poultry Association and, since its first publication in 1972, has been a leading international journal for poultry disease scientists. It publishes material relevant to the entire field of infectious and non-infectious diseases of poultry and other birds. Accepted manuscripts will contribute novel data of interest to an international readership and will add significantly to knowledge and understanding of diseases, old or new. Subject areas include pathology, diagnosis, detection and characterisation of pathogens, infections of possible zoonotic importance, epidemiology, innate and immune responses, vaccines, gene sequences, genetics in relation to disease and physiological and biochemical changes in response to disease. First and subsequent reports of well-recognized diseases within a country are not acceptable unless they also include substantial new information about the disease or pathogen. Manuscripts on wild or pet birds should describe disease or pathogens in a significant number of birds, recognizing/suggesting serious potential impact on that species or that the disease or pathogen is of demonstrable relevance to poultry. Manuscripts on food-borne microorganisms acquired during or after processing, and those that catalogue the occurrence or properties of microorganisms, are unlikely to be considered for publication in the absence of data linking them to avian disease.
