Abstract
Mycoplasma synoviae (MS) is an important pathogens of poultry and turkeys, and causes respiratory infection, lameness, decreased growth rate, loss of egg production and hatch reduction. This study was conducted to determine the seroprevalence of MS infection in industrial poultry of Ardabil province, northwestern Iran, and to find the possible association of prevalence of infection with some potential factors. Between October 2012 and April 2013, 655 blood samples were collected from 36 industrial flocks. Serum samples were examined by Rapid Serum Plate Agglutination (RSPA) and ELISA tests. From 36 flocks, 13 flocks (36.1%) in RSPA and 11 flocks (30.6%) in ELISA were positive. From 655 serum samples, 261 samples (39.8%) and 207 samples (31.6%) were positive in RSA and ELISA tests, respectively. In RSPA, sensitivity, specificity and correlation rate of ELISA were 84.6%, 92.5% and -0.352, respectively. The highest rate of seroprevalance with statistical difference (p
