Between 2000 and 2004 a disease occurred in an aviary in Germany affecting various bird species belonging to the order Passeriformes including Collared Grosbeaks (Mycerobas affinis), Eurasian Bullfinches (Pyrrhula pyrrhula griseiventris), Brown Bullfinches (Pyrrhula nipalensis), Grey-headed bullfinches (Pyrrhula erythaca) and Yellow-bellied Tits (Periparus venustulus). The major clinical signs included increased mortality of fledglings and young birds, as well as feather disorders and feather loss in adult birds. In addition, adult Eurasian Bullfinches showed in one year a disease course, in which the major symptom was inflammation of the skin beginning on the basis of the beak and spreading over the head occurring a few days before death. Bacteriological and parasitological investigations did not reveal any consistent findings. Using a newly developed polymerase chain reaction protocol, DNA of the recently discovered finch polyomavirus (FPyV) was demonstrated in several affected birds. Because of the consistent detection of FPyV-DNA and the similarity of the symptoms with those observed during infection with the closely related avian polyomavirus in other bird species, an etiological role of FPyV in the observed disease is assumed.
2000年至2004年间，德国一个鸟类饲养场发生了一种疾病，影响了雀形目下的多种鸟类，包括白领凤鹛（Mycerobas affinis）、欧亚燕雀（Pyrrhula pyrrhula griseiventris）、褐头雀鹛（Pyrrhula nipalensis）、灰头灰雀（Pyrrhula erythaca）和黄腹山雀（Periparus venustulus）。主要临床症状包括雏鸟和幼鸟死亡率增加，以及成年鸟出现羽毛紊乱和羽毛脱落。此外，成年欧亚燕雀在某一年呈现出一种病程，主要症状是皮肤炎症，始于喙部并蔓延至头部，在死亡前几天出现。细菌学和寄生虫学调查未发现任何一致的结果。使用最近发现的聚合酶链反应方案，在几只患病鸟类中检测到了最近发现的雀科多瘤病毒（FPyV）的DNA。由于持续检测到FPyV-DNA，且症状与其他鸟类感染密切相关的禽多瘤病毒时观察到的症状相似，因此推测FPyV在观察到的疾病中起病因作用。
