“How Bacteria Defend Against Bacteriophages in Hostile Environments” — what this page in the network covers. Bacteria face a constant threat from bacteriophages, viruses that specifically infect and kill them. In environments like the human body, phages can outnumber bacteria by as much as 100 to 1, creating intense selective pressure. Yet bacterial populations persist and even flourish, raising the question of what defense mechanisms allow them to survive. Understanding these survival strategies is crucial because bacteriophages are increasingly explored as alternatives to antibiotics, and bacterial resistance could limit their effectiveness.
The ongoing arms race between bacteria and phages has driven the evolution of diverse bacterial defense systems, including CRISPR-Cas, restriction-modification, and abortive infection. These systems not only protect bacteria but also shape microbial communities and influence human health. As phage therapy gains traction, insights into bacterial countermeasures will be essential for designing robust treatments.
