Amino acids identity %

Bold values refer to our ALV-J Egyptian samples
Nucleotide identities and divergence of sequenced virus isolates comparable to other selected strains from China, Russia, Egypt, the United Kingdom, and the USA. The figure reveals a comparative alignment of the gp85 gene in which, the gp85 nucleotide identity percentage of two of our Egyptian isolates ranges from 71 to 100% comparable to other different reference strains. Besides, the amino acids identity percentage of two of our Egyptian isolates ranges from 77 to 98% comparable to other different reference strains
