Detection and Identification of Avian Orthoavulovirus-1 in Broiler Chickens in Mid and South Areas of Iraq

This study investigates the presence and investigate of Avian Orthoavulovirus-1 (AOAV-1), previously also called avian paramyxovirus-1, in Iraqi broiler chickens. Newcastle disease, a highly contagious and economically important poultry disease, is caused by AOAV-1. A total of 250 samples were collected from 6 Iraqi provinces; Clinically, 150 samples indicated ND. Using PCR and clinical examination, the virus was examined in 150 broiler samples from farms in the north, center and south of Iraq that clinically indicated ND. According to the results (50), 33.3% of the samples tested were positive for PCR detection using the F and HN genes.The results of this investigation may have implications for regional disease control strategies and advance our understanding of the occurrence of AOAV-1 in Iraqi poultry.
