The abundance, complexity, and total length of repeats in FRIK804 compared with nonpathogenic E. coli strain MG1655. Repeat sequences that were ≥ 75 bp were identified and included in analyses. a Repeat sequence abundance was categorized by location and genetic element. Repeats located outside of the designated genetic elements were listed under chromosome. b Complexity was measured by binning repeat sequences according to copy number. c Merged direct (above) and inverted (below) repeat sequences were used to measure both complexity and length. d The length of repetitive regions, areas of the chromosome featuring one or more repeats, was calculated and classified by genetic element
