Genetic properties of ICEHptfs3 and ICEHptfs4 based on the Fischer et al. classifications [9]. The red arrow indicates the T4SS-forming genes. The striped pattern indicates a different sequence compared to ICEHptfs4a. ICEHptfs3 and ICEHptfs4 had different overall genetic structures. ICEHptfs4 had three subtypes based of different alleles of the T4SS-forming genes and other accessories genes
