Prevalência de parasitos intestinais em aves domésticas e silvestres do sul do Brasil. Prevalence of intestinal parasites in domestic and wild birds of the south of Brazil
________________________________________________________________________________ ResumoObjetivou-se monitorar e conhecer a diversidade parasitária de aves domésticas e silvestres através de exames coprológicos. As amostras fecais foram provenientes do Núcleo de Reabilitação e Conservação de Animais Silvestres (Preservas) da Faculdade de Veterinária da Universidade Federal do Rio Grande do Sul, Brasil. As coletas foram executadas por três anos (2015 a 2017), compostas por fezes de 203 aves, distribuídas em 21 Ordens. As fezes foram processadas pelos métodos de Willis-Mollay e de Lutz. A prevalência total foi 38,8% (80/206) com 45,8% (38/80), 40% (26/80) e 27,6% (16/80), respectivamente, em 2015, 2016 e 2017. A rotina na coleta de fezes é relevante para a identificação da fauna parasitária de aves silvestres. A inclusão do tratamento parasitário auxilia na rápida recuperação das aves quando da presença de patologias concorrentes. Palavras-chave: Eimeria spp., Capillaria spp., Ascaridia spp., exames coprológicos.
AbstractThe objective was to monitor and know the parasite diversity of domestic and wild birds through coprological exams. Fecal samples were obtained from the Center for Rehabilitation and Conservation of Wild Animals (Preservas) of the Faculty of Veterinary Medicine of the Federal University of Rio Grande do Sul, Brazil. The collections were executed for three years (2015 to 2017), composed of faeces of 203 birds distributed in 21 Orders. The faeces were processed by the methods of Willis-Mollay and Lutz. The total prevalence was 38.8% (80/206) with 45.8% (38/80), 40% (26/80) and 27.6% (16/80), respectively, in 2015, 2016 and 2017. The fecal collection routine is relevant for the identification on the parasitic fauna of wild birds. The inclusion of parasite treatment assists in the rapid recovery of birds when there are competing pathologies.
This study evaluates the occurrence of gastrointestinal and pulmonary parasites in 266 domestic cats through stool examinations performed in 2018. The cats were adults of several breeds, with tutors and residents in the city of Porto Alegre, Rio Grande do Sul, Brazil. The samples were processed by the methods of Baermann, Willis-Mollay, Lutz and Faust. The occurrence of parasitized cats was 21% (56/266). The parasitic genera were identified: Giardia (26,8%), Toxocara (26,8%), Cystoisospora (17,8%), Ancylostoma (5,3%), Entamoeba (3,6%), Dipylidium (1,8%), Toxocara/Cystoisospora (1,8%), Toxocara/Dipylidium (1,8%) and L1 larvae of Aelurostrongylus abstrusus (14,3%). The occurrence of parasitic infections was significant for zoonotic parasites.
Endoparasitic diseases cause great economic losses, mainly due to the anemias they can cause. This research evaluated the occurrence of gastrointestinal parasites in meat-type sheep of six small gaucho properties. Fecal samples were received at the Helminthology Laboratory of the Faculty of Veterinary, UFRGS, Porto Alegre, RS, and processed by the methods of Gordon & Whitlock (OPG) and Roberts & O’Sullivan (coproculture). The prevalence of infection was 73.86% (113/153), with 87.61% having Strongylida eggs (99/113), in addition to mixed infections with Moniezia and Eimeria. Haemonchus spp. (90%) predominated in coproculture. The high degree of parasitism in animals indicates that more should be invested in integrated control involving animal management and use of medicines.
