The present invention provides an improved methodology by which therapeutically to overcome resistance to tetracycline in living cells including bacteria, parasites, fungi, and rickettsiae. The methodology employs 13-(substituted mercapto) derivatives of tetracycline in combination with other tetracycline-type antibiotics as a synergistic combination of compositions to be administered simultaneously or concurrently. The concomittantly administered compositions effectively overcome the tetracycline resistant mechanisms present such that the cell is effectively converted from a tetracycline-resistant state to a tetracycline-sensitive state. The combination also effects a synergistic bacteriocidal activity against susceptible and resistant cells.
