INFLAMMATION AT THE ATTCHMENT SITEThe worm is scientifically called
Syngamus trachea and the disease is commonly called gapes.
Parasites of freeranging birds included ascarids (Ascaridia species, Porrocaecum species, and other morphotypes), capillarids, oxyurids, strongyles (
Syngamus species and other morphotypes), cestodes (Choanotaenia species, Hymenolepis species, and other morphotypes), a trematode, and protozoans (Eimeria species, Isospora species, Entamoeba species).
(Jimenez, Wearing, Hernandez, Di Mare, Villareal, Cedeno, & Ramirez, 2002; Rodriguez-Ortiz, Garcia-Prieto, & Perez-Ponce de Leon, 2004), mientras que en aves de plantaciones de cafe se han reportado acantocefalos,
Syngamus trachea e Isospora zorzai (Keller, Yabsley, Gibbs, McGraw, & Hernandez 2012; Hernandez, Peters, Weygandt, Jimenez, Villegas, O'Connor, Michael, Yabsley, Garcia, & Carroll, 2013); y en zanates de parques urbanos se reportaron acantocefalos, cestodos sin identificar e Isospora spp.
Haemonchus and Trichostrongylus were the most frequently recorded genera followed by Chabertia, Oesophagostomum, Schistosoma, Moniezia, Cooperia, Bunnostomum, Toxocara, Ostertagia, Nematodirus, Trichuris, Strongyliodes, Avitellina, Fasciola, Thelazia (n=02),
Syngamus, Gaigeria, Skrjabinema, Cotylophoron, Metastrongylus and Gongylonema as mixed or single species infections in different species of animals.
The data indicated prevalence rate of various helminthes including Raillietina achinobothridia (10.4%),
Syngamus trachea (8.4%), Capillaria colombae (6%) and Ascaridia colombae (8.4%).
To the Editor: Mammonogamus laryngeus (
Syngamus laryngeus) is a nematode parasite found in the larynx of tropical mammals (1), especially cattle and cats and occasionally humans (2).
Several feed on blood (Notocotylus attendus,
Syngamus trachea).
Gapeworm (
Syngamus trachea) infection was suspected by the owner, who treated the duck with oral ivermectin at an unknown dose before presentation.
