Avian metapneumovirus (aMPV) is considered a major pathogen for turkeys but its impact on chicken production is still partially neglected, even though it is fully acknowledged as a primary pathogen in chickens as well. The lack of structured diagnostic surveys does not allow a pervasive understanding of aMPV epidemiology. Being that aMPV is almost an everyday challenge for farmers and veterinarians, a more accurate report of its presence should be detailed, posing the basis for a deep and global epidemiologic analysis. With these premises, the present work aims to report the first detection and molecular characterization of aMPV subtype B field strains from unvaccinated chickens in Greece. The Greek strains appear to be phylogenetically related among each other and with other recent Mediterranean strains while being distant from the currently applied vaccines, thus stressing once more the necessity to evaluate aMPV diffusion and evolution.
禽偏肺病毒(aMPV)被认为是火鸡的主要病原体,但它对鸡肉生产的影响仍未得到充分重视,尽管它也被公认为鸡的主要病原体。缺乏系统性的诊断调查使得无法全面了解aMPV的流行病学情况。鉴于aMPV对养殖户和兽医来说几乎是日常面临的挑战,应该详细报告其存在情况,为深入全面的流行病学分析奠定基础。基于这些前提,本研究旨在报告希腊未接种疫苗的鸡群中首次检测到的aMPV B亚型田间毒株及其分子特征。希腊毒株在系统发育上彼此相关,也与其他近期的地中海毒株相关,但与目前使用的疫苗毒株差异较大,这再次强调了评估aMPV传播和进化情况的必要性。
