Resumo: | Parasitic infections are common in sheep farming worldwide. A cross-sectional study was carried out to determine the prevalence and associated risk factors among gastrointestinal parasites and sheep herds from the Brazilian Pampa biome, Rio Grande do Sul state, Brazil. Twenty-one farms were visited, where rectal faecal samples were individually collected from 309 animals. The sheep industry on the studied farms was characterised by small farms with a low level of technification, an extensive grazing system and meat production. Of all samples analysed, strongyle nematodes had the highest prevalence (77.02%), followed by Eimeria spp. (70.55%), Moniezia expansa (20.39%) and Strongyloides papillosus (17.48%). Mixed infection, between helminths and protozoans, was detected in 68.61% of samples. All herds were positive for strongyle and Eimeria spp. A predominance of Haemonchus spp. and Trichostrongylus spp. nematodes was observed in the herds. Younger animals were significantly more affected by Eimeria and M. expansa. In the semi-intensive and intensive systems, a higher frequency of Eimeria and strongyle infections was observed. Parasite infection was significantly reduced at low animal densities. The Brazilian Pampa region presents a high prevalence of gastrointestinal parasites among sheep; age, breeding system and stocking density were factors associated with parasite infection. |

Um estudo transversal foi realizado para determinar a prevalência e fatores de risco associados entre parasitoses gastrintestinais e rebanhos ovinos do bioma Pampa brasileiro, estado do Rio Grande do Sul, Brasil. Vinte e uma fazendas foram visitadas, onde foram coletadas amostras de fezes individuais da ampola retal de 309 animais. A produção ovina era caracterizada por pequenas propriedades com baixo nível de tecnificação, os animais eram criados em sistema extensivo e para produção de carne. De todas as amostras analisadas, os estrongilídeos (Nematoda: Strongylida) foram mais prevalentes (77,02%), seguido por Eimeria spp. (70,55%), Moniezia expansa (20,39%) e Strongyloides papillosus (17,48%). Infecção mista, entre helmintos e protozoários, foi detectada em 68,61% das amostras. Todos os rebanhos foram positivos para estrongilídeos e Eimeria spp. Foi observada predominância dos nematódeos Haemonchus spp. e Trichostrongylus nos rebanhos. Animais mais jovens foram significativamente mais afetados por Eimeria e M. expansa. Nos sistemas semi-intensivo e intensivo, observou-se maior frequência de infecções por Eimeria e estrongilídeos. A infecção parasitária foi significativamente menor em fazendas com baixa densidade animal. A região do Pampa brasileiro apresenta alta prevalência de parasitos gastrintestinais em ovinos; idade, sistema reprodutivo e densidade animal foram fatores associados à infecção parasitária.Sociedade de Medicina Veterinária do Estado do Rio de Janeiro.2022-07-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpeer reviewedAvaliado pelos paresapplication/pdftext/xmlhttps://rbmv.org/BJVM/article/view/125110.29374/2527-2179.bjvm001522Brazilian Journal of Veterinary Medicine; Vol. 44 (2022); e001522Revista Brasileira de Medicina Veterinária; v. 44 (2022); e0015222527-21790100-2430reponame:Brazilian Journal of Veterinary Medicineinstname:Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)instacron:SBMVenghttps://rbmv.org/BJVM/article/view/1251/1242https://rbmv.org/BJVM/article/view/1251/1245Copyright (c) 2022 Natália Soares Martins, Carolina Caetano dos Santos, Sara Patron da Motta, Andrios da Silva Moreira, Nara Amélia da Rosa Farias, Jerônimo Lopes Ruashttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMartins, Natália Soaresdos Santos, Carolina Caetanoda Motta, Sara PatronMoreira, Andrios da SilvaFarias, Nara Amélia da RosaRuas, Jerônimo Lopes2022-08-03T14:36:00Zoai:ojs.rbmv.org:article/1251Revistahttps://rbmv.org/BJVMONGhttps://rbmv.org/BJVM/oaicontato.rbmv@gmail.com2527-21790100-2430opendoar:2022-08-03T14:36Brazilian Journal of Veterinary Medicine - Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)false |
