摘要

The PRRS has caused considerable losses to the swine production world-wide, having affected sows and pigs, causing respiratory and reproductive problems. The PRRS has been related in many countries of Asia, Europe and America. In Brazil, there isn't description of PRRS until the present date, despite the fact of Brazil is next to countries that possess PRRS as Chile and Venezuela (1,2), and to import animals of countries that present the syndrome. Although the necessity to constantly monitor the PRRSin Brazil as monitoring, there are few surveys confirming the absence of the disease in the country (3,4). These surveys had been made until the year of 2001 and after that there weren't trustworthy works in our way. The objective of this is to give continuity to the serological survey of PRRS in the Minas Gerais state (MG) carried through previously (3) and to keep the monitoring of the absence of the agent in Brazil.
