Symptoms include weakness, lethargy, chills, fever, sweating, decreased appetite, headache, back pain and psychological symptoms; and the main cause of death is mainly endocarditic. This study was conducted with the aim to diagnose Brucellosisseroepidemiology in people referred to health and medical centers of Mazandaran province during 2010. Blood samples were taken from participants and after centrifugation and separation of serum, all the received samples first underwent Wright Tube Agglutination test and the samples of Wright tube test with negative or low titers of antibody were used for identifying Blukay antibodies of Standard Coombs Wright Test. To determine whether or not the disease is motile, 2ME Wright Test and Elisa were also conducted. During this study, 337 participants were found positive for Brucellosis. Of these, 25.72% lives in the city and 74.28% is in rural areas.
