The results showed that Non-haemagglutinating activity was showed in the isolate. In agar diffusion test,there was a clear precipitin band formation to anti-IBDV specific serum. 28-day-old chicks inoculated with the isolate showed disease,and the isolate was recovered from the tissues of these chickens.
