Pilus islands in Streptococcus suis. Genomic organization of the pilus islands in strains 05ZYH33, 98HAH33 and P1/7 (a, b and c, respectively) and comparison to pilus island 2b (PI-2b) of Streptococcus agalactiae COH1 (d). These are composed of a gene coding for a signal peptidase I (green arrows), a major pilin protein containing the LPXTG-anchoring motif (orange arrows) that would constitute the pilus backbone, one or two ancillary proteins also containing the LPXTG motif (blue arrows) and one or two class C sortases (red arrows). Other genes within the clusters are shown by white arrows.
