How long has TB been treated?
Tuberculosis has been treated with combination therapy for over fifty years. Drugs are not used singly (except in latent TB or chemoprophylaxis), and regimens that use only single drugs result in the rapid development of resistance and treatment failure. The rationale for using multiple drugs to treat TB are based on simple probability. The rate of spontaneous mutations that confer resistance to an individual drug are well known: 1 mutation for every 10 7 cell divisions for EMB, 1 for every 10 8 divisions for STM and INH, and 1 for every 10 10 divisions for RMP.

When was Streptomycin first used?
Streptomycin and para-aminosalicylic acid were developed by the mid-1940s. In 1960, Edinburgh City Hospital physician Sir John Crofton, addressed the Royal College of Physicians in London with a lecture titled "Tuberculosis Undefeated", and proposed that "the disease could be conquered, once and for all". With his colleagues at Edinburgh, he recognised that germs that developed only a mild resistance to one drug was significant. His team showed that when treating new cases of TB, strict compliance to a combination of three therapies, or the triple therapy, (streptomycin, para-aminosalicylic acid and isoniazid) could provide a complete cure. It became known as the 'Edinburgh method' and became standard treatment for at least 15 years. In the 1970s it was recognised that combining isoniazid and rifampin could reduce the duration of treatment from 18 to nine months, and in the 1980s the duration of treatment was further shortened by adding pyrazinamide.

This was also around the same time that the World Health Organization declared tuberculosis to be a global emergency and recommended countries adopt the DOTS strategy.
