Resumo
Circovirosis, a disease associated to porcine circovirus 2 (PCV2), has been clinically reported as postweaning multisystemic wasting syndrome (PMWS), porcine dermatitis and nephropathy syndrome (PDNS) and other diseases presenting reproductive, respiratory and digestive clinical manifestations. Such diseases are considered emergent and economically important for the pig industry. This study aimed to identify the agent and characterize the clinical, gross and microscopic changes of circovirosis in pig intensive production farms in the state of Goiás, Brazil. For that purpose, 20 pigs with clinical signs of circovirosis from six farms were used. After clinical examination, the pigs were slaughtered, submitted to gross inspection and samples from the spleen, kidneys, lungs, liver and lymph nodes were collected for microscopic analysis and PCV2 identification by PCR. Microscopic changes typical of PCV2 infection were found. PCV2 DNA was identified in all tested animals; however, when compared to clinical signs and gross findings data, only 16 of 20 pigs showed signs of circovirosis. Taken together, the data may support a routine protocol of circovirosis identification and prevention in the state of Goias.
