Abstract

Research highlights: Different field IBDVs were found to circulate in the Near and Middle East.Multiple atypical genotypes (A3B1, A4B1, A6B1) were found to circulate extensively.Traditional very virulent IBDVs (A3B2) were a minority of the detected strains.Viral exchanges can be hypothesized between the region and different continents.

近东和波斯湾地区传染性法氏囊病病毒的分子流行病学。

传染性法氏囊病病毒（IBDV）是一种普遍存在的免疫抑制病原体，给家禽业带来了严重的负担。由于频繁的突变和重组事件，其双链、双链RNA基因组表现出相当大的异质性，这反过来又产生了抗原性和致病性的深刻差异。近年来，IBDV流行病学的研究极大地受益于多种系统发育分类系统的提出，这促使世界各地进行分子调查，产生了丰富的标准化和易于共享的数据。本次流行病学调查在六个近东和波斯湾国家进行，以确定该地区流行的现场IBDV的特征。在一年的时间里，通过一次采集八个单独的法氏囊样本，对93只肉鸡群进行了调查，这些肉鸡群用不同的疫苗接种方案进行了免疫。使用针对两个基因组片段的分子分析，在所有调查国家的42只鸡群中检测到属于四种基因型的现场IBDV。虽然传统的强毒力IBDV（基因型A3B2）占少数，但发现多个非典型IBDV基因型（A3B1、A4B1和A6B1）在该地区的大部分地区传播。许多检测到的毒株与其他大陆的序列有关，这支持近东和中东参与了复杂的病毒传播网络。所获得的结果与现有文献相结合，有助于更新流行病学状况，有望有助于识别流行病学威胁和规划有效的监测和控制策略。

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.
