“…The results of this study corroborate the findings in Washington (USA) [33], which T. cati was one of the two parasites detected in two free-living cougars (P. concolor). However, differing results were found in Rio Grande do Sul (RS) [10] when studying a cougar in captivity; the results showed a mixed infection of Cryptosporidium sp. oocysts, Trichuris sp.…”

Background: Studies on intestinal parasites in cougars Puma concolor are scarce, and most of the available information on the species has been derived from individuals in captivity. One of the greatest threats to the survival of wild cats is habitat loss caused by urban sprawl, agricultural matrix, and linear developments such as highways and railways, which expose animals to direct contact with humans and to a high risk of death. Given the lack of scientific data the objective of this study was to report on the occurrence of intestinal parasites in a cougar (P. concolor) specimen from the northwestern region of Paraná State, Brazil.Case: The carcass of a free-living cougar (P. concolor) individual was sent to the Interdisciplinary Science Museum (Museu Interdisciplinar de Ciências – MIC) of Paranaense University (Universidade Paranaense - UNIPAR); an individual was killed during a collision with an unidentified vehicle on highway PR-486, in the municipality of Mariluz (PR, Brazil). The geographical coordinates of the location where the animal was found are: 23°59′29″S, 53°8′47″W. This region is characterized by semi-deciduous seasonal forest remnants. After being identified on site and collected by the inspectors of the Paraná Environmental Institute (Instituto Ambiental do Paraná - IAP), the cadaver was donated to the MIC (by the IAP) for a necropsy to elucidate the cause of death. In this context, the cadaver was sent to the Animal Pathology section of the Department of Veterinary Medicine at UNIPAR. The animal was necropsied by performing the standard necropsy technique for carnivores: opening the intestine through the mesentery and exposing the mucosa from the duodenum to the colon. The necropsy showed that the cause of death was hypovolemic shock due to trauma. During necropsy, parasites in the intestinal lumen were visible to the naked eye. Parasites and feces were collected and stored in sterile flasks containing 10% formaldehyde and saline. The parasites were subjected to Faust and Hoffman techniques, micrometry, and morphological analysis, resulting in the identification of the roundworm Toxocara cati and the tapeworm Spirometra decipiens.Discussion: Identifying the roadkill species along highways is of paramount importance, since they are living very close to man and, consequently, reservoirs and disseminators of different infectious and parasitic zoonoses may be possible. Infection by protozoa and helminths in animals usually occurs by ingesting the infective form present in food or water. Toxocara cati and the tapeworm Spirometra decipiens were only reported in captivity before. Research on parasites in free-living wild animals is not common in the scientific literature and this is due to the difficulty of capturing this animal category as they live in difficult to access places such as forests and forests, therefore, research projects in partnership with museums are extremely important for the recognition of wild animal species that circulate in the region, in addition to the parasitic identification of these animals for future sanitary measures and for the preservation of the animal species in the environment. The Parasitological studies of wild animals are highly relevant for expanding this knowledge, especially considering the possible transfer risk of specific parasitic diseases to other animals, as well as to humans.

Abstract The 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.

Criptosporidiose em caprinos: A doença e seus impactos na produção

A Criptosporidiose é uma zoonose parasitária de distribuição cosmopolita. O Cryptosporidium spp., agente etiológico da doença, tem localização intracelular, completa seu ciclo biológico na superfície de células epiteliais dos tratos respiratório e gastrointestinal e são responsáveis pela síndrome da “diarreia aquosa”, acarretando em desidratação, perda de peso, retardo no crescimento e morte dos indivíduos infectados. A Criptosporidiose ocorre com maior gravidade em animais neonatos e/ou imunocomprometidos, causando grandes prejuízos econômicos. Os protozoários do gênero Cryptosporidium spp., apresentam ciclo de vida monoxeno, ou seja, o realizam em um único hospedeiro. Em caprinos jovens, menores de 30 dias de vida, o sinal clínico habitualmente observado é o de diarreia severa, que pode durar de 5 a 20 dias comprometendo o crescimento destes indivíduos e podendo levá-los à óbito. O diagnóstico da Criptosporidiose em caprinos pode ser realizado com o uso de técnicas de coloração em esfregaço fecal e Centrífugo-flutuação, de fácil execução e baixo custo, ou ainda por técnicas mais modernas e precisas como a PCR. Pelo conteúdo exposto nesta revisão, é possível concluir que apesar da Criptosporidiose ser uma enfermidade crônica e ainda não ter tratamento efetivo para o combate do seu agente etiológico, tem na prevenção a principal forma de evitar a disseminação da doença no rebanho caprino.
