Spacer graph of the Type II-C CRISPR-Cas systems in B. fragilis. Each numbered node represents a unique spacer. Spacers that are unique to individuals are highlighted in different colors (see color scheme in the plot; spacers shared by isolates from at least two individuals are shown in white). This spacer graph summarizes the spacer organization in 250 CRISPR arrays of Type II-C identified from 187 Zhao2019 isolates. Of particular interest, the funneling shape highlighted in a red triangle is a result of a total of 28 CRISPR arrays involving insertion of six different new spacers (nodes numbered 119, 129, 124, 120, 130 and 63) into the CRISPR arrays after the same spacer (numbered 62)
