Det skyldes etableringen af en eliminationsvej ved at pumpe det antibakterielle stof eller en ændring i transportsystemet, som fører til en begrænset tetracyclin energiafhængig indfangning til cellens ydre.
It is due to the establishment of an elimination route by pumping the antibacterial agent or to an alteration in the transport system, resulting in a limited tetracycline energy-dependent capture to the exterior of the cell.
