MUKUL-YERVES, José Manuel et al. Gastrointestinal and ectoparasites in wildlife-ungulates under captive and free-living conditions in the Mexican tropic. Rev. mex. de cienc. pecuarias [online]. 2014, vol.5, n.4, pp.459-469. ISSN 2448-6698.

Gastrointestinal parasites and ectoparasites were identified in white-tailed deer (Odocoileus virginianus), collared peccary (Pecari tajacu) and brocket deer (Mazama americana) in free-living conditions and captivity in the Mexican tropics. Twelve free-living ungulates were hunted (four white-tailed deer, three brocket deer and five collared peccaries) to obtain samples of faeces and ectoparasites. Fifty-five captive ungulates (14 white-tail deer, 16 brocket deer and 35 collared peccaries) were sampled to obtain faeces and ectoparasites. To identify the genera and order of parasites, faecal samples were analyzed by Flotation and McMaster techniques. Egg and oocyst per gram of faeces were also calculated. Ectoparasites collected from ungulates were classified to genera and species level using specific identification keys. Positive samples of nematode of the order strongylida and protozoos of the order Eucoccidiorida were cultivated and classified. In white-tailed and brocket deer the following genera of parasites were identified: Strongyloides, Trichuris, Capillaria, Mammomonogamus and Eimeria. In collared peccaries the genera Oesophagostomun, Eimeria and Isospora were identified. The flea Pulex irritans and the louse Gliricola porcelli infested brocket deer and collared peccary, while the fly Lipoptena sp was collected from white-tailed deer. The tick Amblyomma cajennese was found parasitizing the three ungulate species studied. It is concluded that wild ungulates are parasitized with gastrointestinal nematodes, protozoa of the order Eucoccidiorida, fleas, lice, flies and ticks.
