Resumo: | Extensive rearing systems enable higher occurrence of helminths, which is a hindrance in poultry farming, significantly affecting productivity. A survey was conducted to determine the prevalence of gastrointestinal helminths in chickens reared in extensive system in the city of Viçosa, Minas Gerais, Brazil between December 2017 to September 2018. A total of 5579 specimens were recovered from the gastrointestinal tracts of most animals (81.55% of prevalence). Of the positive birds, only 41.67% had mixed infections, and of these, more than 90% were nematodes and cestodes co-infections. Three nematodes (Ascaridia galli, Heterakis gallinarum, Capillaria sp.), seven cestodes (Raillietina tetragona, R. echinobothrida, R. cesticillus, Choanotaenia infundibulum, Hymenolepis cantaniana, H. carioca and Davainea proglottina) and two trematodes (Postharmostomum commutatum and Echinostoma sp.) species were identified. The most dominant helminth species was H. gallinarum (60.19%), which also presented higher average intensity (35.46 ± 0.65) and abundance (21.34 ± 3.01) among all recovered species. The tapeworm species correspond to 42.23% of prevalence and the trematodes correspond to only 3.40%. Despite the scarcity of data in the Brazilian literature on poultry helminths reared in extensive systems, regional parasitological surveys are important. It is expected that these results will contribute to the adoption of prophylactic measures and alternative control strategies in order to reduce the risk of helminth infection in poultry |

Um levantamento foi realizado para determinar a prevalência de helmintos gastrointestinais em frangos criados em sistema extensivo na cidade de Viçosa, Minas Gerais, Brasil, entre dezembro de 2017 a setembro de 2018. Um total de 5.579 espécimes foram recuperados do trato gastrointestinal da maioria dos animais (81,55% de prevalência). Das aves positivas, apenas 41,67% tiveram infecções mistas e, destas, mais de 90% foram coinfecções por nematóides e cestóides. Três espécies de nematoides (Ascaridia galli, Heterakis gallinarum, Capillaria sp), sete de cestóides (Raillietina tetragona, R. echinobothrida, R. cesticillus, Choanotaenia infundibulum, Hymenolepis cantaniana, H. carioca and Davainea proglottina) e dois trematódeos (Postharmostomum commutatum and Echinostoma sp.) foram identificadas. A espécie de helmintos mais dominante foi Heterakis gallinarum (60,19%), que também apresentou maior intensidade média (35,46 ± 0,65) e abundância (21,34 ± 3,01) entre todas as espécies recuperadas. As espécies de tênia correspondem a 42,23% da prevalência e os trematódeos correspondem a apenas 3,40%. Apesar da escassez de dados na literatura brasileira sobre helmintos avícolas criados em sistemas extensivos, levantamentos parasitológicos regionais são importantes. Espera-se que esses resultados contribuam para a adoção de medidas profiláticas e estratégias alternativas de controle, a fim de reduzir o risco de infecção por helmintos em aves.Sociedade de Medicina Veterinária do Estado do Rio de Janeiro.2022-06-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpeer reviewedAvaliado pelos paresapplication/pdftext/xmlhttps://rbmv.org/BJVM/article/view/119710.29374/2527-2179.bjvm002121Brazilian Journal of Veterinary Medicine; Vol. 43 No. 1 (2021); e002121Revista Brasileira de Medicina Veterinária; v. 43 n. 1 (2021); e0021212527-21790100-2430reponame:Brazilian Journal of Veterinary Medicineinstname:Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)instacron:SBMVenghttps://rbmv.org/BJVM/article/view/1197/1208https://rbmv.org/BJVM/article/view/1197/1211Copyright (c) 2021 Marisa Caixeta' Valadão, Ítalo Stoupa Vieira, Lorendane Millena de Carvalho, Paulo Henrique Neves, Rafaela Teixeira Magalhães, Artur Kanadani Campos, Jackson Victor de Araújohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessValadão, Marisa Caixeta'Vieira, Ítalo Stoupade Carvalho, Lorendane MillenaNeves, Paulo HenriqueMagalhães, Rafaela TeixeiraCampos, Artur Kanadanide Araújo, Jackson Victor2022-06-26T22:05:30Zoai:ojs.rbmv.org:article/1197Revistahttps://rbmv.org/BJVMONGhttps://rbmv.org/BJVM/oaicontato.rbmv@gmail.com2527-21790100-2430opendoar:2022-06-26T22:05:30Brazilian Journal of Veterinary Medicine - Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)false |
