Tuberculosis(TB) in the past also called phthisis, phthisis pulmonalis, or consumption, is a widespread, infectious disease caused by various strains of mycobacteria, usually Mycobacterium tuberculosis.
In 2009, 58% of all TB cases were culture confirmed, however the level differed widely across countries (range: 44.0%?100.0%).
The recommended treatment of new-onset pulmonary tuberculosis is six months of a combination of antibiotics containing rifampicin, isoniazid, pyrazinamide, and ethambutol for the first two months, and only rifampicin and isoniazid for the last four months
A number of medications are being studied for multi-drug resistant tuberculosis. The safety and effectiveness of these new agents are still uncertain since they are result of limited studies.
