Fig. 1. — Nucleic acid Phylogenetic relationships of S gene avian infectious bronchitis virus (IBV) detected from backyard chicken in Iran, 2014. The phylogenetic tree was generated using neighboring joining model with MEGA (version 5.1 beta). Numbers below branches indicate bootstrap value from 1000 replicates, bootstrap values. Horizontal distances are proportional to the minimum number of Nucleic acid differences required to join nodes. The vertical lines are for spacing branches and labels. The analysiswas based on complete open reading frames of all gene segments. The scale bar represents the distance unit between sequence pairs. The virus genome characterized in this report is indicated as Black Circle. White triangle is indicated for previous Iranian IBV isolates from commercial poultry farms. The sequences obtained from Gene Bank.
