Psittacine neuropathic gastric dilatation was studied in four cockatoos (Cacatua spp.). The birds died with characteristic clinical signs, and post-mortem examination revealed a highly distended proventriculus. Upon light microscopic examination, most of the ganglia of the gastric plexus and some of the duodenal myenteric plexus appeared destroyed and replaced by round cell accumulations; the same was true for the celiac ganglion. The neuronal perikaryon of the celiac ganglion and the myenteric plexus revealed intranuclear and extranuclear eosinophilic inclusion bodies. The electron microscope revealed virus-like particles outside and within those inclusions. These particles were similar to particles described and identified as paramyxovirus.
对四只凤头鹦鹉（白凤头鹦鹉属）进行了鹦鹉神经性胃扩张的研究。这些鸟死于特征性临床症状，尸检发现腺胃高度扩张。在光学显微镜检查中，胃丛的大多数神经节和十二指肠肌间神经丛的一些神经节似乎被破坏，并被圆形细胞聚集所取代；腹腔神经节也是如此。腹腔神经节和肌间神经丛的神经元核周体显示有核内和核外嗜酸性包涵体。电子显微镜显示这些包涵体内外有病毒样颗粒。这些颗粒与被描述并鉴定为副粘病毒的颗粒相似。
