Abstract

aMPV is known as a virus associated with respiratory disease of poultry, which is usually accompanied by secondary bacterial infections which causes reduced growth and increased mortality and decreased egg production, especially in the turkey. In this research, to investigate the infection of commercial broiler chicken farms in Qazvin province with aMPV, tracheal swabs was taken of birds from 20 broiler chicken farms that had respiratory diseases complex (three swabs from each farm). The samples tested by RT-PCR for the presence of aMPV. Results obtained indicated that 13 flocks out of 20 flocks were infected with aMPV, which accounted for 65 infection rate of the flocks. As seen from sample, aMPV was high and significant in Qazvin province, indicating importance of identify this virus.
