HELMINTOFAUNA DEL APARATO DIGESTIVO Y RESPIRATORIO DE AVES ACUÁTICAS (ANATIDAE: ANATINAE) DEL HUMEDAL DE ATLANGATEPEC, TLAXCALA, MÉXICO.

The purpose of this investigation was to carry out the first inventory of helminths collected from waterfowl (n=52) of the family Anatidae. This work took place in wetland Atlangatepec, Tlaxcala. Helminths were collected from the digestive tract and the respiratory system of waterfowl donated by hunters. Collected parasites were processed using conventional fixation and staining techniques for the identification of helminth. Twenty-one taxa of helminth swere identified as follow: seven trematodes (Cotylurus cornutus, Australapatemon burti, Zygocotyle lunata, Notocotylus seineti, Typhlocoelum sisowi, Echinostoma sp. and Echinoparyphium recurvatum), four cestodes (Hymenolepis sp, Cloacotaenia megalops, Choanotaenia infundibulum and Fimbriaria fasciolaris), eight nematodes (Amidostomum sp., Streptocara sp., Epomidiostomum uncinatum, Syphaciella sp., Capillaria sp., Tetrameres fissispina, Tetrameres sp. and Echinuria uncinata) and two Acanthocephala (Pseudocorynosoma constritum and Polimorphus sp.). It is relevant to highlight that this is the first report of Syphaciella sp. in waterfowl in Mexico. [ABSTRACT FROM AUTHOR]
