Morfologia e taxonomia de nematoides em Saltator similis Lafresnaye & D'orbigny, 1837 (Trinca-ferro)

Abstract

This study addresses a taxonomic and morphological study of the diversity of nematodes found in Saltator similis Lafresnaye & d'Orbigny, 1837 (green-winged saltator). The 50 birds necropsied were provided by the Juiz de Fora unit of the Wild Animal Screening Center (CETAS) of the Brazilian Institute of the Environment and Renewable Natural Resources (IBAMA). The helminths were collected, fixed, and prepared on semi-permanent slides mounted in Amann's lactophenol. The material was analyzed using a BX51TF microscope with an Olympus DP74 digital camera with differential interference contrast (DIC) and cellSens Standard v.4.2 image analysis software. The statistical study was performed using jamovi version 2.6.44 and Quantitative Parasitology on the web (QPweb), version 1.0.15. Morphological analyses and a literature review confirmed the occurrence of Aproctella Alessandroi Bain, Petit, Kozek & Chabaud, 1981 in the peritoneal cavity and Capillaria Zeder, 1800 in the host's gastrointestinal tract. In the literature, there is a scarcity of information, which demonstrates the importance of this academic approach. Further research is still needed to establish which species of Capillaria parasitizes the host analyzed. In the long term, this information, combined with studies of the possible clinical impacts caused by such parasites and their biological cycles, demonstrates potential for the creation of management and preservation strategies, especially in environments where birds are raised and conserved.
