<p>Maximum likelihood method (GTR+G+I substitution model) using concatenated sequences of three genes (16S rRNA, <i>GyrB</i>, <i>PyrH</i>) (2560 bp). Bootstrap percentages above 80% are represented by grey dots at the parent nodes. Virulence of each strain is depicted by the grey bars on the outer ring (a value of 100 corresponds to 100% mortality during inoculation experiments). Assignment to the different clades (see legend) based on 99% sequence similarity by BLASTN analysis is depicted in color on the inner ring.</p
