Antimicrobial agents that can serve as replacements to conventional pharmaceutical antibiotics are disclosed. The antimicrobial agents comprise conjugatively transmissible plasmids that kill targeted pathogenic bacteria but are not harmful to donor bacteria. Two types of lethal transmissible plasmids are disclosed. One type kills recipient bacteria by unchecked ("runaway") replication in the recipient cells and is prevented from occuring in donor cells. Another type kills recipient bacteria by expressing a gene that produces a product detrimental or lethal to recipient bacterial cells that gene being prevented from expression in donor cells.

Why it's free to use
- Filed August 30, 2001 and granted July 9, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 30, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 30, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
