Evolution of the CRISPR-Cas9 defence system in <i>Mycoplasma gallisepticum</i> following colonization of a novel bird host

2023-03-14

Abstract excerpt

CRISPR-Cas systems are bacterial defences that target bacteriophages and mobile genetic elements. How these defences evolve in novel host environments remains, however, unknown. We studied the evolution of the CRISPR-Cas system in Mycoplasma gallisepticum , a bacterial pathogen of poultry that jumped into a passerine host ∼30 years ago. Over the decade following the host shift, all isolates displayed a functional...
