Infectious bronchitis is an acute viral disease with high contagious and mortality among chicks. The
aim of this study was to survey of relation between ascites syndrome incidence and infectious bronchitis in
broiler chickens by ELISA method in Iran. Eight Ross strain broiler farm affected by infectious bronchitis were
selected in this study. Blood samples were gathered early stages of disease and blood sampling was repeated
two times with seven days interval. ELISA serologic test was used for approving the determination of infectious
bronchitis. In addition, in order to differential diagnosis of Newcastle and influenza (H9N2) some relevant
experiments were conducted. The rate of mortality in any farm during rearing, autopsy and the cause of
mortality were recorded. Ascites cases were calculated in terms of prevalence. The growth parameters, FCR,
final weight, total consumption of grain at each farm were calculated and mentioned. Based on obtained results
in this study, the mean rate of mortality caused by ascites syndrome has been increased meaningfully in herds
affected by infectious bronchitis compared with control group. In eight understudied farms affected by
infectious bronchitis, the mean rate of Ascites mortality was 3% such that the mean rate of Ascites mortality
was 0.5% at previous periods. Based on relevant results also final weight mean in affected herds with infectious
bronchitis was lower compared with previous periods. Meanwhile, FCR in affected herds with infectious
bronchitis was high compared with healthy herds. In this research demonstrated that there is positive correlation
between infectious bronchitis and Ascites syndrome and the correlation is significant (p<0.05).
