摘要

临床病史:在大约180只孔雀中,有几只出现了可能的上呼吸道感染迹象,主人张大了嘴巴。据报道,他们还嗜睡,口腔中有过多的痰或粘液,吞咽困难,体重正在减轻。他们正在接受拜屈和甲硝唑的治疗,但没有任何改善。大约有8人死亡。五只孔雀被提交进行尸检和诊断检查,其中包括三只孔雀和两只孔雀。大体发现:在所有五只孔雀中,口腔都含有过量的粘液。口腔、作物和食道粘膜有播散性、光滑、隆起的圆形结节,带有中心孔。食管近端是受影响最严重的部位。结节的平均直径约为2毫米。挤压其中一些结节后,可以表现出浅褐色的干酪状物质。在所有五只孔雀中,心脏都被大量的白色、白垩质、尿酸盐物质所覆盖。类似但数量较少的尿酸盐部分覆盖了肝脏和其他体腔膜的表面。在一只母鸡身上,输尿管多发性扩张,并含有棕褐色至浅黄色干酪状物质的固结堆积物。这只鸟的肾脏是苍白的。

Vitamin A deficiency in peafowl with secondary visceral urate deposition
Clinical History: In a flock of approximately 180 peafowl, several were showing signs of a possible upper respiratory infection and had mouth gaping per the owner. They were also reported to be lethargic, to have excessive phlegm or mucus in the mouths, had trouble swallowing, and were losing weight. They were being treated with Baytril and Metronidazole with no improvement. Approximately eight had died. Five peafowl were submitted for necropsy and diagnostic work-up, including three peahens and two peacocks. Gross Findings: In all five peafowl, the oral cavity contained excess mucus. The oral, crop, and esophageal mucosa had disseminated, smooth, raised, round nodules with a central pore. The proximal esophagus was the most severely affected site. The nodules measured on average ~2 mm in diameter. Upon squeezing some of these nodules, pale tan, caseous material could be expressed. In all five peafowl, the heart was diffusely coated by abundant white, chalky, urate material. Similar though lesser amounts of urates partially coated the surface of the liver and other coelomic membranes. In one peahen, the ureters were multifocally distended and contained consolidated accumulations of tan to pale yellow, caseous material. The kidneys in this bird were pale.
