Fig. 2

Circular diagrams and in silico comparison of two S. suis genomes(S.suis1 (a) and S.suis2 (b)) . From outside to inside, in circle 1, the coding genes of COG outside (inside) represent the genes located on the positive (negative) strand, different colors represent different biological functions. In circle 2 (black circle), the GC contents of the genomes were shown. In circle 3, GC skew [(G-C)/(G + C)] is displayed (Green indicates values> 0, and purple indicates values< 0)
