First report of Strongyloides sp. (Nematoda, Strongyloididae) in Leopardus tigrinus (Carnivora: Felidae) in the municipality of Botucatu, State of São Paulo, Brazil

Abstract

The present study reports the first case of infection by Strongyloides sp. in Leopardus tigrinus in the municipality of Botucatu, State of São Paulo, Brazil. Feces of the infected L. tigrinus specimen were cultivated in sterilized equine feces and a cat (Felis catus domesticus) was experimentally infected with three thousand infective L 3 subcutaneous route, in order to identify the Strongyloides species involved in the parasitism. Parthenogenetic females recovered from the experimental animals were analyzed but comparison between the biometric data found and the data in the literature did not enable identification of the species. This is the first report on the occurrence of Strongyloides sp. in L. tigrinus.

Pathologies of Oligacanthorhynchus pardalis (Acanthocephala, Oligacanthorhynchidae) in Leopardus tigrinus (Carnivora, Felidae) in Southern Brazil

“…The oncilla (L. tigrinus), an endangered feline, occurs in all Brazilian biomes (SUNQUIST; SUNQUIST, 2002 fauna of this species is poorly known, although six parasite species (one cestode, three nematodes and two acanthocephalans) have been identified (DIESING, 1851apud BELDOMENICO et al, 2005TRAVASSOS, 1917;PETROCHENKO, 1971;HUNGRIA, 1978;SANTOS et al, 2009;GALLAS;SILVEIRA, 2011 Acanthocephalan species cause damage to their hosts in the area where the proboscis is attached, which may cause formation of nodules, granulomas and inflammations, and may predispose towards secondary infections (NICKOL, 1985;RICHARDSON;BARNAWELL, 1995;KENNEDY, 2006). Babero (1957) and Richardson and Barnawell (1995) …”

Gastrointestinal parasites among felids inhabiting the Serra dos Órgãos National Park, Rio de Janeiro, Brazil

“…Since fecal samples were collected directly from the environment, these larvae could possibly be forms of free-living nematodes. However, there is also the possibility that these larvae could be hookworms, Strongyloides sp., although infection by these helminths has only been infrequently reported (SANTOS et al, 2009), or even metastrongilids, especially those which have mollusks as intermediate hosts, such as Aelurostrongylus sp. (PATTON & RABINOWITZ, 1994;FIORELLO et al, 2006;DI CESARE et al, 2016).…”

Parasitos gastrointestinais em Puma concolor, Puma yagouaroundi e Leopardus pardalis (Carnivora: Felidae) na Floresta Nacional de Três Barras, SC, Brasil

“…Strongyloides sp. é descrito principalmente em gatos domésticos em vários países do mundo, inclusive no Brasil (Vicente et al, 1997;Bowman et al, 2002), tendo um único registro em felídeos silvestres no país na espécie L. tigrinus (Santos et al, 2009). Machos adultos de Strongyloides sp.…”

“…Vários autores descrevem a presença de parasitos em felídeos selvagens (Patton et al, 1986;Rickard e Foreyt, 1992;Patton e Rabinowitz, 1994;Xavier et al, 2000;Freitas et al, 2001;Pence et al, 2003;Tantaleán e Michaud, 2005;Vieira et al, 2008;Santos et al, 2009), porém, apesar da importância do ponto de vista conservacionista, são poucos os dados recentes. Estudos de parasitos em felídeos ameaçados no sul do Brasil ainda são incipientes, principalmente nos animais que estão em áreas protegidas.…”
