Abstract: The present invention relates to the field of bacterial vectors and methods for genetic manipulation of bacteria. In particular, the present invention relates to a vector for genetic manipulation of a bacterium, wherein said vector comprises (a) a non-antibiotic selection marker gene cassette, (b) an origin of replication, wherein said origin of replication is not capable of inducing replication of said vector in said bacterium, and (c) a restriction endonuclease gene, a recognition site of a restriction endonuclease encoded by said restriction endonuclease gene, and a second regulatory sequence. Further, the invention relates to a bacterial host cell comprising said vector, a method for genetic manipulation of bacteria using the vector of the invention, and methods for selecting bacterial host cells.

Abstract: The invention relates to compounds and pharmaceutical compositions useful in combination with tetracyclines in the treatment of bacterial infections caused by Gram-positive and Gram-negative pathogens, with particular efficacy in tetracycline resistant strains. These compounds specifically bind to TetR and therefore prevent the transcriptional activation of tet resistance genes. The compounds have a potentiating effect on the activity of members of the tetracycline family, in particular of tetracycline, minocycline, doxycycline and tigecycline, in the treatment of tetracycline susceptible, intermediate and tetracycline resistant pathogens.
