The Impact on Human Health Understanding that bacteria can be infected by viruses has significant implications for medicine. These proteins act as quality control scanners, cutting up any foreign DNA that enters the bacterial cell, including phage DNA.

Nutrient depletion, extreme temperatures, and desiccation (drying out) can cripple their metabolic functions. Bacterial Defense Mechanisms Because bacteria are under constant threat from phages, they have not remained defenseless.
When a bacterium survives a phage infection, it can incorporate a snippet of the viral DNA into its own genome. This relationship is a classic example of a predator-prey dynamic playing out at the microscopic level, keeping bacterial populations in check naturally.

Furthermore, bacteria are engaged in constant warfare with other microorganisms. In the lytic cycle, the phage replicates rapidly and causes the bacterial cell to burst, or lyse, which is lethal.
