Phylogenetic analysis of MDV based on Meq protein amino acid sequences. phylogenetic tree was constructed via multiple alignments of amino acid sequence of Meq protein of 28 reference strains and the eight Egyptian sequences using a distance-based neighbour joining method with bootstrapping (1000) with MEGA6.06 software. Egyptian MDV Sequences of this study and earlier one was indicated using green triangle and red circle, respectively. Clades EUA and NA are abbreviation for Eurasian and North American.
