To acquire this capacity they must be repetitively exposed to antibiotics in order to incite the “mutation pressure” that nudges them toward complete drug immunity.

Pour leur permettre d’acquérir cette résistance, ils doivent être exposés de façon répétée aux antibiotiques afin de fournir la «pression de mutation» qui les pousse vers l’immunité complète.
