## Abstract

The present invention relates to a vector, preferably included in a delivery vehicle, comprising no more than 100, preferably no more than 10, restriction sites recognized by the restriction enzymes encoded by each bacterium of a group of bacteria of interest. The invention also relates to the use of said vector, preferably included in a delivery vehicle, as a drug, especially in the treatment of a disease in a patient in need thereof.
