Abstract:RESUMO A infecção por Capillaria hepatica foi diagnosticada por exame histológico em 4 de 24 (16,6%) animais necropsiados. A parasitose foi inesperada e considerada um achado incidental de necropsia. Dados relativos ao sexo, idade, lesões macro e microscópicas dos animais parasitados são apresentados e discutidos.
AbstractThe aim of the present study was to evaluate the state of knowledge about the helminthology of wild mammals in Argentine Patagonia and its link with the conservation of parasite species and biodiversity. To this end, the information included in the previously reported checklist of the helminths found in terrestrial wild mammals of Argentine Patagonia was completed and updated. The methodology used for the search was the same as that previously used, with slight modifications. Eighty-two species of mammals currently inhabit the region, and an additional six species are considered to have become extinct before the 20th century. The reports used to complete and update the information correspond to research done since 2015 to date. Considering the number of records analysed in the previously reported checklist and those of the current update, a total of 1918 helminthological reports for current Patagonian mammals and 2141 on mammal species that inhabited Patagonia before the 20th century were accounted for. It is important to point out that 41% of the 82 species of wild mammals currently inhabiting Patagonia have not been studied helminthologically; 38% of these without helminthological records are either threatened or do not have categorization, and 79% of mammals without helminthological studies have some degree of endemism. Therefore, in order to evaluate conservation priorities, the information about the parasitic richness in Patagonian wild mammals should be substantially increased, especially in those endangered or endemic.

This study aimed to identify the intestinal parasites of road-killed wild felines in the North Central and North, Paraná state, southern Brazil. The animals were monitored by sampling previously established transects. The places where the felines were run over were mapped, the animals were identified, and the gastrointestinal tract was evaluated. The feces were submitted to coproparasitological techniques of spontaneous sedimentation, floating in hypersaturated NaCl solution and centrifugal floating in zinc sulfate. All the parasitic structures detected were photomicrographed. In the coproparasitological analyses were identified oocysts of Cystoisospora spp., eggs of Ancylostomatidae, and Capillaria spp.; eggs of Aelurostrongylus spp., Toxocara spp., Physaloptera spp., Taenia spp., and Spirometra spp.; Aelurostrongylus abstrusus larvae; and eggs and adults of Ancylostoma cati and Taenia spp. One of the cats was parasitized by a flea of Ctenocephalides felis felis. Based on these results, the animals analyzed in this study supplied important samples for the evaluation of parasitic diversity of North of Paraná and suggested that this region may have conditions that allow the maintenance of these parasites life cycles in the environment and among wildlife.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
