Mycobacterium tuberculosis is also found in the stool of patients with intestinal TB7 or in PLHIV with diarrhoea or enteritis.
What is the pathophysiology of tuberculosis?

What is MTB detected?
The Xpert MTB/RIF assay is a new test that is revolutionizing tuberculosis (TB) control by contributing to the rapid diagnosis of TB disease and drug resistance. The test simultaneously detects Mycobacterium tuberculosis complex (MTBC) and resistance to rifampin (RIF) in less than 2 hours.

The Genexpert diagnoses TB by detecting the presence of TB bacteria. The test is a molecular TB test which detects the DNA in TB bacteria. It uses a sputum sample and can give a result in less than 2 hours. The Genexpert can also detect the genetic mutations associated with resistance to the drug Rifampicin.
