Abstract:
The aim of this study was to register the first occurrence of Synhimantus (Dispharynx) nasuta (Nematoda: Acuariidae) in some species of wild birds in Brazil. In addition, the aim was to deepen the knowledge about the morphology of this species through analysis using scanning electron microscopy. Nematodes were collected in wild birds of the species Turdus leucomelas, T. rufiventris, Mimus saturninus, Pitangus sulphuratus, Megascops choliba, Tyto furcata, and Falco sparverius. The morphological and morphometric data observed in the nematodes prove that these parasites are S. (D.) nasuta. This study also provides morphological data from light microscopy and scanning electron microscopy (SEM), as well as the morphometry of this nematode in each host species. Therefore, the current study confirms the first record of this nematode in F. sparverius and T. furcata in South America and, at the same time, these findings expand the host range of this parasite species worldwide, through the first records in M. choliba, M. saturninus, T. leucomelas and T. rufiventris.
摘要:
这项研究的目的是在巴西某些野生鸟类中首次出现Synhimantus(Disphynx)nasuta(Nematoda:Acuariidae)。此外,目的是通过使用扫描电子显微镜进行分析来加深对该物种形态的了解。线虫是在Turdusleucomelas物种的野生鸟类中收集的,T.Rufiventris,Mimussaturninus,硫黄,Megascopscholiba,TytoFurcata,还有法尔科·斯派维里斯.在线虫中观察到的形态和形态数据证明这些寄生虫是S.(D.)纳苏塔。本研究还提供了来自光学显微镜和扫描电子显微镜(SEM)的形态学数据,以及这种线虫在每个宿主物种中的形态计量学。因此,目前的研究证实了这种线虫在南美洲的Sparverius和T.Furcata中的第一个记录,同时,这些发现扩大了世界范围内这种寄生虫的宿主范围,通过M.choliba的第一记录,M.saturninus,T.leugomelas和T.rufiventris。
