Two adult male Crimson rosellas (Platycercus elegans) and an adult female eastern rosella (Platycercus eximius) were found dead in their cages in a private aviary in March 2009, April 2010, and February 2010, respectively, without premonitory signs. Their postmortem examination showed pectoral muscle atrophy and a distended proventriculus. The proventricular mucosal surface was covered with a gelatinous, whitish material, where a large number of nematode parasites identified as Dispharynx nasuta were present. A histologic examination revealed a hyperplastic mucosa, spirurid nematodes in the mucosal layer and inflammatory mononuclear cells in the lamina propria. This is the first report of a D. nasuta infection associated with proliferative proventriculitis and subsequent death in psittacine birds.
2009年3月、2010年4月和2010年2月，分别有两只成年雄性绯红玫瑰鹦鹉（Platycercus elegans）和一只成年雌性东部玫瑰鹦鹉（Platycercus eximius）被发现死在私人鸟舍的笼子里，死前没有任何预兆。尸检显示胸肌萎缩和腺胃扩张。腺胃黏膜表面覆盖着一层凝胶状的白色物质，其中存在大量被鉴定为鼻管圆线虫（Dispharynx nasuta）的线虫寄生虫。组织学检查显示黏膜增生、黏膜层有旋尾线虫以及固有层有炎性单核细胞。这是关于鼻管圆线虫感染与鹦鹉鸟类增生性腺胃炎及随后死亡相关的首次报告。
