Lineage and Virulence of Streptococcus suis Serotype 2 Isolates from North America
|ST||No. strains||srtF pilus cluster
||srtG pilus cluster
||Pili expression‡, Sfp1||Gene†
||Pili expression, Sgp1‡|
*ST, sequence type.
†The presence of the genes was detected by PCR by using primers and conditions described by Takamatsu et al. (13).
‡Expression of pili encoded by the srtF and srtG pilus clusters was performed by Western blotting by using described antibodies directed against the major subunits of these structures (16,17).
