What bacteria causes drug resistant tuberculosis?
What bacteria causes drug resistant tuberculosis?
Some forms of TB are also resistant to second-line medications, and are called extensively drug-resistant TB (XDR-TB). Tuberculosis is caused by infection with the bacteria Mycobacterium tuberculosis….Multidrug-resistant tuberculosis.

How do you develop drug resistant TB?
Sometimes drug-resistant TB occurs when bacteria become resistant to the drugs used to treat TB. This means that the drug can no longer kill the TB bacteria. Drug-resistant TB (DR TB) is spread the same way that drug-susceptible TB is spread. TB is spread through the air from one person to another.
How does TB meningitis cause hydrocephalus?
The exact pathogenesis of hydrocephalus in tuberculous meningitis is unclear. The hydrocephalus is probably a result of basal adhesive meningeal reaction wherein the flow of the CSF is obliterated in its course from the point of exit from the fourth ventricle to the site of its absorption in the arach- noid villi.
What causes brain TB?
TB is caused by a bacterium called Mycobacterium tuberculosis. If the infection is not treated quickly, the bacteria can travel through the bloodstream to infect other organs and tissues. Sometimes, the bacteria will travel to the meninges, which are the membranes surrounding the brain and spinal cord.
How common is drug resistant tuberculosis?
According to the report, approximately 20% of TB cases globally are estimated to be resistant to at least one of the first- or second-line anti-TB drugs, and 5% are resistant to both isoniazid and rifampicin, the most powerful and commonly used antibiotics in first-line treatment.
How do you know if you have drug resistant TB?
Drug resistance can be detected using special laboratory tests which test the bacteria for sensitivity to the drugs or detect resistance patterns. These tests can be molecular in type (such as Xpert MTB/RIF) or else culture-based.
