Phylogenetic tree of the 21 hepatitis B virus isolates obtained in this current study. The phylogenetic tree was created by Methodes et Algorthmes pour la Bio-Informatique (MABL)-Laboratoire d’Informatique, de Robotique et de Microélectronique de Montpellier (LIRMM), Université Montpellier, North-West of Montpellier, France. The branch length is proportional to the number of substitutions per site25.
