Seroprevalence and genotyping of avian infectious bronchitis virus detected from Iranian unvaccinated backyard chickens.

ABSTRACT:

Background and objectives

Different epidemiological studies have found that backyard chickens are a reservoir for poultry diseases. Most backyard chicken flocks have a poor level of biosecurity, which increases the risk of spread of diseases. In recent years, the number of backyard chickens has been on the rise in Iran. However, the health status of backyard flocks is still poorly documented. Thus, this study aimed at examining the seroprevalence of antibodies against infectious bronchitis virus (IBV) and molecular surveillance and genotyping of IBV among backyard chickens (without vaccination history) in Mazandaran province, North of Iran, 2014.

Materials and methods

A total of 460 blood samples of unvaccinated backyard chickens in the mentioned area were tested for antibod
