Abstract

Research highlights: Increase in FAdV infections (IBH and GEUS) in Morocco over past decade.FAdV-positive cases were mainly found in broiler farms (79%).Identification of FAdV-11 and 8b serotypes for IBH, and FAdV-1, 8a and 8b for GEUS.

摩洛哥家禽中的禽鸟腺病毒：2012 - 2024年流行禽鸟腺病毒株的病理特征和系统发育分析

在过去十年中，摩洛哥出现了禽类腺病毒感染，即包涵体肝炎（IBH）和砂囊侵蚀和溃疡综合征（GEUS），给家禽业造成了重大损失。本研究对2012 - 2024年全国不同家禽生产类型中255例IBH和GEUS疑似禽群病例进行了评估。受感染鸡的宏观病理改变包括肝脏变大、变色或砂囊肿胀，伴有出血内容物和koilin层糜烂/溃疡。显微镜检查结果显示严重的坏死性肝炎，与IBH一致，和/或坏死性脑室炎，这是GEUS的特征，肝细胞或砂囊上皮细胞中的核内病毒包涵体（INIB）可归因于家禽腺病毒（FAdV）。实时PCR结果显示，71% (182/255)FAdV疑似病例检测呈阳性。患病率因家禽生产类型而异，肉鸡养殖场受影响最大，为79%(144/194)，其次是蛋鸡养殖场，为15%(28/42)，种鸡养殖场为5%(9/13)，火鸡养殖场为1%（1/6）。分离株测序结果显示，22例和6例IBH分别为FAdV血清11型（D种）和8b型（E种）。此外，在9例和2例GEUS中分别检测到FAdV血清1型（A种）和8a、8b血清型（E种）。这些发现强调了禽类腺病毒对摩洛哥家禽业的重大影响，并强调了持续监测和有针对性的控制干预措施的必要性。研究强调在过去十年中摩洛哥的FAdV感染（IBH和GEUS）有所增加。fadv阳性病例主要发生在肉鸡养殖场（79%）。IBH和GEUS FAdV-1、8a和8b血清型的鉴定。

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.
