Resumo: | Porcine respiratory disease complex comprises the interaction of two or more infectious agents. The major bacterial agents involved were investigated in 115 finishing pigs at a farm in São Paulo State, Brazil: Actinobacillus pleuropneumoniae (serology, bacterial culture, and multiplex PCR), Mycoplasma hyopneumoniae (Mhyo) (nested PCR), Pasteurella multocida (multiplex PCR), Haemophilus parasuis (PCR multiplex), and Streptococcus sp. (bacterial culture). Macroscopic and microscopic lung lesions were evaluated, and zootechnical indices were recorded. Mhyo occurred in 113 animals (98.3%), seventeen of which were co-infected with Streptococcus sp. The finding of emphysematous lung was associated with significantly lower final and carcass weight at slaughter. Although vaccinated against Mhyo with an inactivated immunogen, almost 100% of the animals were infected. Mhyo infection with and without Streptococcus sp. co-infection was related to lung lesions of varying degrees and lower slaughter and carcass weight.Keywords: differential diagnosis, Mycoplasma hyopneumoniae, pleuropneumonia, Streptococcus sp., swine |

Os principais agentes bacterianos causadores de CDRS foram investigados em 115 suínos em fase de terminação em uma granja no Estado de São Paulo, Brasil: Actinobacillus pleuropneumoniae (sorologia por ELISA, cultivo bacteriano e PCR multiplex), Mycoplasma hyopneumoniae (Mhyo) (nested PCR), Pasteurella multocida (PCR multiplex), Haemophilus parasuis (PCR multiplex), e Streptococcus sp (cultivo bacteriano). Foram avaliadas lesões pulmonares macroscópicas e microscópicas, e impacto nos índices zootécnicos e no aproveitamento de carcaça. Houve positividade ao Mhyo em 113 animais (98,26%), destes houve infecção associada ao Streptococcus sp ao Mhyo em 14,78% (17) animais. O pulmão enfisematoso diminuiu significativamente o peso no final da terminação e o peso da carcaça. Apesar de vacinados com imunógeno inativado contra Mhyo, quase 100% dos animais estavam infectados e as lesões mais observadas foram broncopneumonia purulenta e pleurite. A infecção de Mhyo associado ou não ao Streptococcus sp causou lesões pulmonares em diferentes graus, menor peso ao abate e da carcaça.Palavras-chave: suínos, pleuropneumonia, diagnóstico diferencial, Streptococcus sp, Mycoplasma hyopneumoniae.Universidade Federal de Goiás2019-10-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/51615Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 20 (2019): Continuous publication; 1-12Ciência Animal Brasileira / Brazilian Animal Science; v. 20 (2019): Publicação contínua; 1-121809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGengporhttps://revistas.ufg.br/vet/article/view/51615/33834https://revistas.ufg.br/vet/article/view/51615/33836https://revistas.ufg.br/vet/article/view/51615/33835https://revistas.ufg.br/vet/article/view/51615/33837Copyright (c) 2019 Ciência Animal Brasileirainfo:eu-repo/semantics/openAccessBrombilla, TalitaOgata, Renato AkioNassar, Alessandra Figueiredo de CastroCardoso, Maristela VasconcelosRuiz, Vera Letticie de AzevedoDel Fava, Claudia2023-03-23T18:49:21Zoai:ojs.revistas.ufg.br:article/51615Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:56:21.963299Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
