The medical standard for active TB is a short course treatment involving a combination of isoniazid , rifampicin (also known as Rifampin), pyrazinamide , and ethambutol for the first two months.
Cord factor, or trehalose dimycolate (TDM), is a glycolipid molecule found in the cell wall of Mycobacterium tuberculosis and similar species. It is the primary lipid found on the exterior of M. tuberculosis cells. [1] Cord factor influences the arrangement of M. tuberculosis cells into long and slender formations, giving its name. [2]
Mycolic acids are long fatty acids found in the cell walls of Mycobacteriales taxon, a group of bacteria that includes Mycobacterium tuberculosis, the causative agent of the disease tuberculosis. They form the major component of the cell wall of many Mycobacteriales species. [ 1 ]
M. tuberculosis can also grow on the lipid cholesterol as a sole source of carbon, and genes involved in the cholesterol use pathway(s) have been validated as important during various stages of the infection lifecycle of M. tuberculosis, especially during the chronic phase of infection when other nutrients are likely not available.

Directly observed treatment, short-course (DOTS, also known as TB-DOTS) is the name given to the tuberculosis (TB) control strategy recommended by the World Health Organization. [1] According to WHO, "The most cost-effective way to stop the spread of TB in communities with a high incidence is by curing it.
MDR-TB most commonly develops in the course of TB treatment, [5] and is most commonly due to doctors giving inappropriate treatment, or patients missing doses or failing to complete their treatment. Because MDR tuberculosis is an airborne pathogen, persons with active, pulmonary tuberculosis caused by a multidrug-resistant strain can transmit ...
For the treatment of tuberculosis, cycloserine is classified as a second-line drug. Its use is only considered if one or more first-line drugs cannot be used. Hence, cycloserine is restricted for use only against multiple drug-resistant and extensively drug-resistant strains of M. tuberculosis.
Roughly one-quarter of the world's population has been infected with M. tuberculosis, [6] with new infections occurring in about 1% of the population each year. [11] However, most infections with M. tuberculosis do not cause disease, [169] and 90–95% of infections remain asymptomatic. [87] In 2012, an estimated 8.6 million chronic cases were ...
