Pseudomonas aeruginosa cells adapted to Rosmarinus officinalis L. essential oil and 1,8-cineole acquire no direct and cross protection in a meat-based broth

► R. officinalis essential oil (ROEO) and 1,8-cineole (CIN) inhibited P. aeruginosa. ► Exposure of P. aeruginosa to sublethal amounts of ROEO or CIN induced no protection. ► Cells grown in increasing amounts of ROEO or CIN presented no changes in tolerance.
