Pan-genome analysis of M. catarrhalis prophages. The pan-genome of 32 M. catarrhalis prophages is 283,622 bp in length, and is represented in the BRIG image above as the central black ring. Each concentric circle outwards from the reference pan-genome represents an individual prophage colour coded according to the assigned clades (red = clade 1, blue = clade 2, orange and yellow = clade 3, green = clade 4). A percentage identity cut-off above 90 % was used, which is represented by different hues in each ring (minimum of 90 % = grey, and up to maximum of 100 % = colour assigned to specific ring and prophage)
