The authors do not seem to distinguish the application of these to terms to bacteria, in which antibiotic resistance can be said to " evolve", vs the resistance elements themselves, which usually remain the same, but "emerge" in new bacteria and "spread" to others. Is it possible that the use in the medical literature examined refers not to the evolving bacteria but to the spreading (horizontal transfer) of resistance elements? The genetic literature, on the other hand, probably refers more often to the changes in the bacterial genomes, which "evolve" by the "acquisition" of these (unchanged) elements.
