RESUMO
Aelurostrongylus abstrusus, popularly known as "feline pulmonary worm", it is a nematode that affects the respiratory system of felines causing aelurostrongylosis. This parasite can be found in the host's bronchi and pulmonary arteries. The clinical signs presented vary according to the animal's immune response and severity of the infection, the host might present apathy, dyspnea, syncope, wheezing, sneezing, among others. This report aims to describe a case of aelurostrostrilylosis in a feline of wildlife threatened of extinction. The animal, Leopardus wiedii (Schinz, 1821), popularly known as Margay, was found in an urban perimeter in the municipality of Anchieta, state of Santa Catarina (SC) in Brazil and attended at the Veterinary Clinic CLINIVET, of the University of the West of Santa Catarina - UNOESC, campus of São Miguel do Oeste (SC). In the initial clinical evaluation, the patient presented with deambulatory difficulties, biological samples were collected for further investigation. In the coproparasitological exam, parasitism was diagnosed by A. abstrusus, however the animal did not present any clinical signs related to the respiratory system. The results of this report indicate that the species L. wiedii, diagnosed with subclinical infection, can act as a wild reservoir for A. abstrusus, serving as a source of infection for other species of wild felids and also for domestic ones. This highlights the importance of effective public policies for the conservation, management and study of diseases that affect wild cats, especially species that need more urgent attention, that is, those threatened of extinction.(AU)
Aelurostrongylus abstrusus, popularmente conhecido como "verme pulmonar felino", é um nematoide que aco-mete o sistema respiratório dos felinos causando aelurostrongilose. Este parasita pode ser encontrado nos brônquios e arté-rias pulmonares do hospedeiro. Os sinais clínicos apresentados variam de acordo com a resposta imune do animal e gravi-dade da infecção, podendo o hospedeiro apresentar apatia, dispneia, síncope, sibilos, espirros, entre outros. Este relato tem como objetivo descrever um caso de aelurostrongilose em um felino silvestres ameaçado de extinção. O animal, Leopardus wiedii (Schinz, 1821), popularmente conhecido como gato maracajá, foi encontrado no perímetro urbano do município de Anchieta, estado de Santa Catarina (SC), Brasil e atendido na Clínica Veterinária CLINIVET, da Universidade do Oeste de Santa Catarina - UNOESC, campus de São Miguel do Oeste (SC). Na avaliação clínica inicial o paciente apresentava dificuldade de locomoção, foram coletadas amostras biológicas para posterior investigação. No exame coproparasitológico foi diagnosticado parasitismo por A. abstrusus, porém o animal não apresentou nenhum sinal clínico relacionado ao sis-tema respiratório. Os resultados deste relato indicam que a espécie L. wiedii, diagnosticada com infecção subclínica, pode atuar como reservatório silvestre para A. abstrusus, servindo como fonte de infecção para outras espécies de felinos silves-tres e também para os domésticos. Isso destaca a importância de políticas públicas efetivas para a conservação, manejo e estudo das doenças que acometem os felinos selvagens, principalmente as espécies que necessitam de atenção mais urgente, ou seja, aquelas ameaçadas de extinção.(AU)

Oslerus osleri (O. osleri) is a filaroid nematode of the respiratory tract of domestic and wild canids that leads to parasitic tracheobronchitis. The aim of this study was to report the first occurrence of O. osleri in hoary fox in Minas Gerais State, Brazil. The animal was found struck by vehicle in a periurban area and died before any clinical procedures were attempted. At necropsy the animal showed multiple bone fractures. The mucosa of the middle and distal part of the trachea, and primary bronchi were irregular and moderately thickened, containing numerous cylindrical parasites forming nests, firmly adhered to the mucosa. Histopathological examination revealed diffuse inflammation of the mucosa and numerous parasites embedded in the lamina propria with nematode characteristics. The parasitological evaluation including morphological structures and the size of parasites confirmed the occurrence of O. osleri in the Brazilian hoary fox. The conclusion of this report is that Brazilian hoary fox is naturally infected by O. osleri and this finding is important to know the distribution and epidemiology of this little known parasite in Brazil.
