EXAME ANATOMOPATOLóGICO, MICROBIOLóGICO, CITOLóGICO E FíSICO-QUíMICO DAS ARTICULA??ES DE SUíNOS ARTRíTICOS NO MATADOURO

摘要

Estudou-se por meio de exames anatomopatológico, microbiológico, citológico e físico-químico, as articula??es de 130 suínos abatidos em um matadouro localizado em Concórdia ? SC. Os animais foram escolhidos de forma direcionada e as articula??es foram classificadas macroscopicamente de acordo com as les?es presentes na membrana sinovial, cartilagem articular e no linfonodo regional. Dos 130 suínos escolhidos, 25 apresentavam-se com as articula??es normais, 36 com artrite causada pela osteocondrose, 50 com artrite infecciosa e 19 com artrite traumática. Em todos os casos de artrite infecciosa havia rea??o do linfonodo regional e, da mesma forma, sempre que os linfonodos regionais estavam reativos, havia artrite infecciosa no membro relacionado. Dos 50 casos de artrite infecciosa, 40 (80%) eram assépticos, de sete (14%) foi isolado o Erysipelothrix rhusiopathiae e de três (6%), o Mycoplasma hyosynoviae, pela primeira vez isolado no Brasil. Nas demais categorias de artrite, n?o foram isolados nenhum agente infeccioso e nem visualizadas altera??es nos linfonodos regionais. Conclui-se que as artrites infecciosas s?o acompanhadas de rea??o dos linfonodos regionais e as artrites causadas pela osteocondrose s?o estéreis. Pathological, microbiological, cytological and physical-chemical studies of joints from arthritic swines in the abattoir Abstract The joints of one hundred and thirty pigs from an abattoir in Concórdia - SC, were studied, by means of pathological, microbiological, cytological and physical-chemical procedures. The choice of the pigs was not made by random distribution and the joints were grouped grossly according of lesions of the synovial membrane, cartilage and of the draining lymph node. From 130 pigs, 36 showed lesions of osteochondrosis, 50 infectious arthritis, 19 traumatic arthritis and 25 normal joints. In all cases of infectious arthritis there was a reaction of the corresponding draining lymph node. Whenever the draining lymph node was reactive, there was infectious arthritis in the related limb. Of the 50 infectious arthritis, 40 (80%) were aseptic, 7 (14%) yielded Erysipelothrix rhusiopathiae and 3 (6%) yielded Mycoplasma hyosynoviae, for the first time isolated in Brazil. In the remaining arthritis categories, no infectious agents nor alterations in the draining lymph node was diagnosed.
