禽源冠状病毒感染情况概述

摘要

Based on epidemiological investigation,surveillance,gene analysis of coronaviruses in birds in the world,coronavirus infections and the related diseases in avian were summarized in this paper. Avian-origin coronavirus has a very complex population with abundant diversity,involving viruses in Gammacoronavirus and Deltacoronavirus at least. Avian infectious bronchitis virus existed and was endemic in almost all chicken-producing countries. Turkey coronavirus,duck coronavirus,goose coronavirus,pigeon coronavirus were already detected in avian and some of these were pandemic. A few other Deltacoronavirus were only detected in wildfowl .%以国内外对冠状病毒在禽类中的流行病学调查、监测和基因分析等研究报道为基础，从病毒分类学角度，对各“种”冠状病毒在禽类中的感染情况和引起的相关疾病进行简要概述。全球在禽类中发现的冠状病毒种类较多，至少涉及丙型和丁型冠状病毒属。其中，鸡传染性支气管炎病毒几乎在全球所有养鸡国家中存在，并呈地方性流行；火鸡冠状病毒、鸭冠状病毒、鹅冠状病毒、鸽冠状病毒也在禽类中被发现，部分病毒已在禽群中流行；其他丁型冠状病毒属病毒仅在少数野鸟中被发现。
