There is little data on the positivity of this disease in Brazil. The objective of this study was to evaluate the seropositivity for this agent in 200 serum samples collected from pigs in a slaughterhouse located in the central region of São Paulo. A high percentage (52%) of positivity was found indicating the presence of the agent and the need to implement control measures.1899-1903porM. hyopneumoniaeepidemiologiasuínosM. hyopneumoniaeepidemiologyswineArtigo10.1590/S0102-09352013000600045S0102-09352013000600045WOS:000329450600045Acesso abertoS0102-09352013000600045.pdf
