Western scientists are researching the effectiveness of bacteriophage viruses, which are already used in Russia and Poland, for the treatment of many different bacterial infections due to various potentially multi-drug resistant organisms such as Staphylococcus aureus, E.coli, Streptococci, Ps aeruginosa and tubercle bacilli. They were abandoned outside of Eastern Europe during the beginning of the chemotherapeutic era but may be extremely effective in the treatment of a broad-spectrum of bacterial infections resistant to just about all currently available drugs.
They infect bacterial cells, use them to replicate, then destroy them in a way similar to that used by viruses to infect human cells. When organisms develop resistance to phages new variants can easily be found because phages also mutate meaning that resistance to them may not present a major problem.
