Soropositividade para Mycoplasma hyopneumoniae em suínos abatidos em frigoríficos da região central do estado de São Paulo / Seropositivity for Mycoplasma hyopneumoniae in pigs at a slaughterhouse in the Central region of São Paulo

ABSTRACT

Mycoplasma hyopneumoniae is the etiologic agent of enzootic pneumonia in pigs and causes large economic losses in the swine industry. 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.
