Gastrointestinal parasites among felids inhabiting the Serra dos àrgÆos National Park, Rio de Janeiro, Brazil
2018  Braz J Vet Parasitol (27): 131-140

This study aimed to investigate the species of felids that inhabit the Serra dos àrgÆos National Park (Parnaso) and gastrointestinal parasites at various stages of their life cycles in the feces of these animals. Between 2013 and 2015, felid feces were collected from trails in Parnaso. The sampling points were georeferenced. A total of 82 fecal samples were processed, of which 79 were collected on the ground, two from captured felids and one from a necropsied animal. All samples underwent coproparasitological techniques. Samples collected from the environment underwent additional trichological analysis. Fur patterns corresponding to _Leopardus guttulus, Leopardus pardalis, Leopardus wiedii _and_ Puma yagouaroundi_ were observed in 32 of the samples collected on the soil. High frequency of potentially parasitic evolving forms (88.6%) was observed in felid feces, particularly eggs of the family Diphyllobothriidae (68.6%). Besides, were also detected, eggs of superfamily _Ascaridoidea_ (42.9%), nematode larvae (28.6%), eggs of order _Strongylida_ (28.6%),_ Capillaria sp_. (8.6%),_ Trichuris sp_. (8.6%), eggs of order _Spirurida_ (2.9%), unsporulated coccidian oocysts (8.6%) and _Eimeria sp_. (2.9%). Felid feces presented higher frequency of polyparasitism (60%) than monoparasitism (28.6%).
