An update survey of the MDV strains circulating in the Egyptian poultry flocks during 2015 -2016 was conducted. Twenty one vaccinated chicken flocks suffering from different form of lymphomas, representing different governorates in the Egyptian Delta, were screened for MDV infection. Pathological findings in the visceral tumours and presence of viral DNAs with variable mitotic figures were observed in the examined visceral organs. Eight samples were screened positive for the major MDV-encoded oncogene Meq which was subjected for alignment and phylogenetic analysis.
