Tuberculosis, a bacterial lung infection, is one of the leading causes of death worldwide and is becoming increasingly resistant to antibacterial treatments. 

Tuberculosis, caused by Mycobacterium tuberculosis, is a highly infectious lung disease in humans.Unfortunately, resistance to anti-tubercular medicines such as fourth-generation fluoroquinolones is on the rise. In most cases, fluoroquinolone resistance is caused by mutations in a bacterial enzyme called gyrase.
