Parasitosis in commercially important captive wild species can cause losses due to decreased productivity, increased veterinary expenses, secondary infections and animal mortality. An analysis was done to quantify endoparasite prevalence and abundance in the cervids Odocoileus virginianus and Mazama temama in captivity. Fecal samples (n= 60) were collected during the rainy and dry seasons from six O. virginianus and four M. temama of different ages and sexes. Endoparasites were extracted using the flotation technique with a saturated sugar solution, and the parasites identified by anatomical comparison. Seven parasite genera were identified: Ascaris sp.; Eimeria sp.; Estrongilido sp.; Strongyloides sp.; Parascaris sp.; Paragonimus sp.; and Taenia sp. In both cervid species Ascaris sp. and Eimeria sp. exhibited the highest abundance. Males and females of each cervid species exhibited different parasite prevalences. Parascaris sp. and Paragonimus sp. were found only in O. virginianus. No differences (P>0.05) were present in parasite abundance between the rainy and dry seasons. The genus Ascaris was generally more abundant than the other parasite genera (P<0.05). These results will be useful in the control and prevention of parasites in captive ungulates.
