Immune loss as a driver of coexistence during host-phage coevolution

ISME JOURNAL, 12(2), 585–597.

By: J. Weissman*, R. Holmes*, R. Barrangou n, S. Moineau*, W. Fagan*, B. Levin*, P. Johnson*

MeSH headings : Bacteria / genetics; Bacteria / immunology; Bacteriophages / physiology; Biological Evolution; CRISPR-Cas Systems; Models, Immunological
