The swine from the present study confront with serious breathing and reproduction problems specific to PRRS disease (Rotaru 2005). This disease affects the immune system of pigs and has a concomitant evolution with another viral and bacterial infection. PRRS is recognized around the world by the economical impact that it produces in swine breeding units (Perianu T. et al 2005). It is a viral disease with endemic evolution characterized by reproduction alert signs to sows and by breathing signs to young pigs( Benfield, 1999). In most of the cases of evolution the multiple ethyology includes the following bacterium: Mycoplasma hyopneumoniae, Pasteurella multocida, Actinobacillus pleuropneumoniae and viruses: virus Aujeszky virus, porcine reproductive and respiratory syndrome, influenza virus, transmissible gastroenteritis virus and virus respiratory coronavirozei, low conditions of maintenance will overtake the protection mecanism of the body (Benfield, D 1999). In this paper are presented the epidemiological researches achieved during 2011 in two proffesional swine units from Braila.
