The proventriculi of 11 Eurasian cranes (Grus grus) from central Iran were examined for the existence of parasitic helminths. Preliminary reports suggested that the death of these birds was related to untimely cold weather. Nine proventriculi (82%) were heavily infected by the nematode Tetrameres grusi. Glandular structure of the infected proventriculi was replaced by epithelial atrophy but significant inflammatory reactions were not observed in any of the infected organs. In serious infections, the nematode produced vast structural and functional changes, causing organ dysfunction and glandular necrosis. The coincidence of heavy helminth infection at times of environmental stress may lead to debilitation, wasting, and perhaps mortality in migratory cranes.
对来自伊朗中部的11只欧亚鹤（Grus grus）的前胃进行了检查，以确定是否存在寄生蠕虫。初步报告表明，这些鸟类的死亡与不合时宜的寒冷天气有关。9个前胃（82%）被线虫格鲁斯四棱线虫严重感染。受感染前胃的腺体结构被上皮萎缩所取代，但在任何受感染器官中均未观察到明显的炎症反应。在严重感染时，线虫会产生巨大的结构和功能变化，导致器官功能障碍和腺体坏死。在环境压力时期，严重的蠕虫感染可能会导致迁徙鹤衰弱、消瘦，甚至死亡。
