Resumen
Guignas (Leopardus guigna) are small felids closely associated with native forest habitats. In fragmented land scapes, they use vegetation corridors and forest remnants to move across the landscape. In these contexts, gui gnas may increase contact probabilities with domestic animals, being therefore relevant to assess their pathogens
and parasites. The aim of this study was to characterize the helminth fauna in the gastrointestinal tract and
cardiorespiratory system of guignas from central and southern Chile. Between 2015 and 2018, 33 dead free ranging guignas were found road-killed or were collected from wildlife rescue centers. Thirty-two gastrointes tinal tracts and 32 cardiorespiratory organs were analyzed through direct analysis and artificial digestion. We
found 81.8% (27/33) guignas were positive for helminth endoparasites (84.4% (27/32) positive for gastroin testinal parasites, 37.5% (12/32) positive for cardiorespiratory parasites). Fourteen parasites were identified (7
at genus level and 7 at species level), with Angiostrongylus sp., Molineus sp., Oslerus sp. and Troglostrongylus sp. as
first records in guignas. The most prevalent parasites were the species Toxascaris leonina, Toxocara cati and
Uncinaria stenocephala. Uncinaria stenocephala showed the highest intensity of infection. Multiparasitism was
observed in 76% of the animals. Significant differences in richness of endoparasites and prevalence of cardio respiratory parasites were found between geographic zones; higher values in the southern zone are possibly due
to favorable environmental characteristics for endoparasite development. There were no statistically significant
differences between sexes. All the parasites found in this study have been previously reported in domestic cats.
These results are valuable to understand parasite transmission at the domestic-wildlife interface; the possibility
of endoparasite transmission between domestic cats and guignas should be clarified with molecular analysis.
