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.

Article Synopsis
- A significant parasitic nematode of cranes, classified as part of the Spirurina suborder, has a controversial classification that has persisted for over a century.
- The complete mitochondrial genome of this nematode was sequenced, revealing a circular structure with 13,709 bp, containing 12 protein-coding genes and high AT content similar to other Spirurina species.
- Phylogenetic analyses showed that this nematode is more closely related to Spiruroidea than to Thelazioidea, providing valuable genetic markers for future research on Spirurina nematodes.
