From: Contribution of pilus type 2b to invasive disease caused by a Streptococcus agalactiae ST-17 strain
Type 2b pili contribute to infection in vivo by ST-17 COH1. Ten CD-1 mice (8-week-old) for each group were injected via tail vein with 1.5 × 108 Colony Forming Units (CFU) of wild-type COH1 (WT), Δbp-1 or Δbp-2b mutants. Blood, brains and lungs were collected upon euthanasia at day 2 post-infection, the tissues were homogenized and plated for enumeration of bacterial CFU. Horizontal lines represent median CFU values. Differences between groups were analyzed by Kruskal-Wallis test followed by Dunn’s multiple comparisons test. Only statistically significant differences are reported (*P < 0.05, **P < 0.01, ***P < 0.001)
