From: Characterization of motility and piliation in pathogenic Neisseria
Quantification of piliation in FAM20, MS11 and FA1090 using transmission EM. (A and B) The graphs show the percentage of bacteria observed with x number of single pili (A) or pili bundles (irrespective of bundle width) (B) that appear to emanate from the bacteria. The total number of bacteria observed per strain were: FAM20 n = 48, MS11 n = 49, FA1090 n = 44. Significant differences was tested for by using t-test (two-tailed and non-equal variance), values are not significantly different. (C) Quantification of bundle width (nm), with each dot representing one bundle. The lines indicate the median bundle width. (D) Fraction of single and bundle-associated pili (from estimates of the number of pili in each bundle). The mean and standard deviation from two to three experiments are shown.
