Numerous bacteria have been selected by humans and used extensively for fermentation and biotechnology processes. Unfortunately,
domesticated bacteria used in industrial applications are often susceptible to phage attack, including genera and species
widely used as dairy cultures (4).
Which bacteria are most susceptible to these phage attacks? Those that do not contain these CRISPR sequences? It would be interesting to see the breadth of phages that this "immune response" of bacteria could fight off.
