red by the
S. suis 2 isolates from China. Five of 12 structural genes, including
cps2B, cps2D, cps2F, cps2K, and
cps2L exactly matched those of
S. suis P1/7. In contrast, seven structural genes showed some point variations. The divergent genes included
cps2A (G163A, F273I, and F302L),
cps2C (I160V and Q195K),
cps2E (G190E, W264L, and S281C),
cps2G (F183Y),

Figure 1 Comparison of the cps2 Gene Clusters Involved in CPS-2 Synthesis Exactly matched genes (5/12) include cps2B, cps2D, cps2F, cps2K, and cps2L and are shown in pink. The seven other genes (which did not exactly match) include cps2A cps2C, cps2E, cps2G, cps2H, cps2I, and cps2J and were highlighted with green in S. suis P1/7 and with red in both S. suis 98 and S. suis ZY.
