Bacteriophages are probably the oldest viruses, having appeared early during bacterial evolution. Therefore, bacteria and bacteriophages have a long history of co-evolution in which bacteria have developed multiple resistance mechanisms against bacteriophages. These mechanisms, that are very diverse and are in constant evolution, allow the survival of the bacteria. Bacteriophages have adapted to bacterial defense systems, devised strategies to evade these anti-phage mechanisms and restored their infective capacity. In this chapter, we review the bacterial strategies that hinder the phage infection as well as the counter-defense mechanisms developed.

The Psu protein of phage satellite P4 inhibits transcription termination factor ρ by forced hyper-oligomerization.

Many bacteriophages modulate host transcription to favor expression of their own genomes. Phage satellite P4 polarity suppression protein, Psu, a building block of the viral capsid, inhibits hexameric transcription termination factor, ρ, by presently unknown mechanisms. Our cryogenic electron microscopy structures of ρ-Psu complexes show that Psu dimers clamp two inactive, open ρ rings and promote their expansion to higher-oligomeric states.

Type III CRISPR-Cas executes a multifaceted anti-phage response, activating effectors such as a nuclease or membrane depolarizer. In a recent Cell paper, Baca and Majumder et al. report an accessory effector, Cad1, which deaminates ATP into ITP, causing ITP accumulation and host growth arrest, thereby inhibiting phage propagation.

Bacterial resistance has emerged as one of the greatest threats to human health, and phages have shown tremendous potential in addressing the issue of drug-resistant bacteria by lysing host. The identification of phage-host interactions (PHI) is crucial for addressing bacterial infections. Some existing computational methods for predicting PHI are suboptimal in terms of prediction efficiency due to the limited types of available information.

Background: Oral infectious diseases, such as dental caries, periodontitis and periapical periodontitis, are often complicated by causative bacterial biofilm formation and significantly impact human oral health and quality of life. Bacteriophage (phage) therapy has emerged as a potential alternative with successful applications in antimicrobial trials. While therapeutic use of phages has been considered as effective treatment of some infectious diseases, related research focusing on oral infectious diseases is few and lacks attention.
