Phylogenetic Trees of Six Representative Isolates Based on Comparison of 16S rDNA and Five Putative Virulence-Associated-Factor Genes with Known Sequences
<p>Swine isolates from Sichuan (
S. suis ZYS3 and
S. suis ZYS8) labeled in green, human isolates (
S. suis ZYH13 and
S. suis ZYH14) from Sichuan labeled in red, Jiangsu isolates from 1998 (
S. suis 9801 and
S. suis Habb) labeled in blue, and the standard highly virulent strain
S. suis P1/7 labeled in pink. All representative strains from other streptococcus species or isolates of
S. suis 2 are as indicated in the tree.
