Tuberculosis is caused by a bacterium Mycobacterium tuberculosis. Many years ago streptomycin easily controlled the bacterium. Now streptomycin is much less effective against the resistant M. tubercul?

Tuberculosis is caused by the bacterium Mycobacterium tuberculosis, which has developed resistance to many antibiotics over time, including streptomycin. Initially, streptomycin was effective in treating tuberculosis, but the emergence of drug-resistant strains has made it less effective. This resistance complicates treatment and necessitates the use of more potent and often more toxic second-line drugs. Ongoing surveillance and development of new treatments are critical in managing resistant tuberculosis.
