Figure 1: Phylogenetic analysis based on hemolysin gene sequences from the NCBI database. Phylogenetic analysis based on hemolysin gene sequences constructed after multiple alignment data by CLUSTAL W. The clustering was performed with the Maximum likelihood method (GTR+G model) using the software package MEGA version 5.05. Bootstrap confidence levels are shown as percentages on nodes (consensus tree; only branches with confidence values above 50% are shown).
