Phage mechanisms to avoid bacterial resistance
| Phage counter-attack mechanisms | ||
|---|---|---|
| Phage (host) | Mechanism | Effect |
| ICP2 (V. cholerae) | Mutational change of tail fibers | Recognition of non-wild-type OmpU (Seed et al. 2014; Lim et al. 2021) |
| ICP1 (V. cholerae) | Epigenetic modification | OrbA protein counteracts the BREX system (LeGault et al. 2021) |
| ICP1 (V. cholerae) | Endonuclease | Endonuclease that mimics the PLE-encoded replication initiation factor RepA (Barth et al. 2021; Boyd et al. 2021) |
| ICP1 (V. cholerae) | CRISPR-Cas | CRISPR-Cas system against V. cholerae PLE (Seed et al. 2013) |
| Several phages | tRNA acquisition | tRNAs support translation of late genes during phage infection (Yang et al. 2021) |
