a Clustering of the eight sequenced strains based on a similarity matrix containing the total number of prophages (Total), the total number of active prophages (Active), the total number of inoviridae (Inoviridae) and presence (black square)/absence (white square) of shared prophages that have been found in more than one genome (Φ1, Φ2, Φ6, Φ18) different colours correspond to bacterial groups: orange: HS bacteria, blue: IS bacteria and R: resistant bacteria; b Maximum likelihood tree based on whole genome alignment of the eight sequenced strains
