New preprint!
Ever wondered why only a fraction of genomes encode CRISPR immunity? 🧬 🦠
Turns out CRISPR is rarely beneficial against virulent phages, being most beneficial against those for which resistance mutations are rare!

Out in Nature Microbiology, we predicted phage-bacteria interactions in E. coli species using only genomic information.
Adsorption, not defense systems, is the main driver at this scale (relevant for a phage therapy context), leading to tailored cocktails!
