A case of pulmonar parasitosis caused by Aelurostrongylus abstrusus in (Railliet, 1898) a adult cat is described, with clinical monitoring, laboratory and imaging test, and treatment for 14 months. During follow-up, the cat presented larvae of A. abstrusus in the Baermann parasitological methods and in the fecal smear with treatments and relapses of the parasite in the exams. Radiographic images showed diffuse opacification of the lung fields with an interstitial pattern, tending to alveolar, with visualization of thickened bronchial walls, related to an inflammatory/infectious process. The persistence of lungworm disease is discussed and the treatment.

The objective of this work is to report gastrointestinal parasitism in dogs and cats abandoned during the May 2024 flood, rescued and adopted in Porto Alegre, Rio Grande do Sul, Brazil. From June to October 2024, fecal samples from 93 pets (15 dogs and 78 cats) were analyzed using five parasitological techniques. Of the total number of pets (15 dogs and 78 cats), the frequencies of positive samples were 46.6% (7/15) and 43.6% (34/78), respectively, for dogs and cats. The parasites present in dogs were: Ancylostoma caninum (Ercolani 1859), Trichuris vulpis (Frolich 1789), Cystoisospora felis (Wenyon, 1923; Frenkel 1977), and Toxocara canis (Werner, 1782); in cats, they were: T. canis, C. felis, Giardia sp., larvae of Aelurostrongylus abstrusus (Railliet, 1898) and Strongyloides sp., A. caninum, Dipylidium caninum (Linnaeus, 1758), and Dioctophyma renale (Goeze, 1782).

The objective of this study is to evaluate the frequency of gastrointestinal parasites in free-living marsupials received at the Veterinary Clinics Hospital of the Federal University of Rio Grande do Sul, southern Brazil. Fecal samples from nine white-eared opossums (Didelphis albiventris Lund, 1841) and three thick-tailed opossums (Lutreolina crassicaudataDesmarest, 1804) were processed by the Willis and Lutz methods. Both species of marsupials presented nematode eggs and/or protozoan oocysts in their feces. In white-eared opossums, eggs of Ancylostoma spp. Ercolani, 1859 and Capillaria spp. Zeder, 1800 (4/8 - 50%), Ancylostoma spp. and Cruzia tentaculata (Rudolphi, 1819) Travassos, 1917 (2/8 - 25%), C. tentaculata (2/8 - 25%) and oocysts of Eimeria spp. Schneider, 1875 (1/8 - 12.5%) were identified. The only hatchling presented eggs of Ancylostoma spp., Trichuris spp. Roederer, 1761 an...
