This study was conducted to characterize nine infectious bursal disease virus (IBDV) isolates from Iran. A reverse

transcriptase–polymerase chain reaction (RT-PCR) procedure was used to amplify a 743-bp fragment of the VP2 gene...

single-stranded genome. The genome has 3 open reading frames encoding 3 viral proteins (VP1, VP2, and VP3).

In the present study, samples from commercial broiler chickens from liver, spleen and thymus from Northeast Iran,

were screened by PCR and VP2 gene...
