What is PhoPR?
PhoPR is a well-known regulator of pathogenic phenotypes, including secretion of the virulence factor ESAT-6, biosynthesis of acyltrehalose-based lipids, and modulation of antigen export, in members of the Mycobacterium tuberculosis complex (MTBC).
What is the size of tuberculosis?
tuberculosis is carried in airborne particles, called droplet nuclei, of 1– 5 microns in diameter. Infectious droplet nuclei are generated when persons who have pulmonary or laryngeal TB disease cough, sneeze, shout, or sing. TB is spread from person to person through the air.
What is Caseum in tuberculosis?
Caseum, the central necrotic material of tuberculous lesions, is a reservoir of drug-recalcitrant persisting mycobacteria. Caseum is found in closed nodules and in open cavities connecting with an airway.
Why does TB have beaded appearance?
Due to their waxy cell wall components, the bacilli of MTB are acid fast; that is, they retain the red dye, carbol fuchsin, after rinsing with acid solvents. Often, the bacilli have a beaded appearance.
What tuberculosis looks like?
The purple rod-shaped organism is a TB bacterium. This name, meaning ‘fungus-bacteria’ refers to shape of the bacillus when it grows in a laboratory: when seen through a microscope it forms heaps of small rods with protective layers around them, and thus looks like a fungus.
Why does TB form granulomas?
Dendritic cells are important because they present antigens to T cells in the lymph nodes, in which a T-cell response can subsequently be developed. These signalling events lead to the formation of a granuloma, the hallmark of tuberculosis.

What is the treatment for granuloma in the lungs?
Lung granuloma treatment For example, a bacterial infection in your lungs that triggers granuloma growth should be treated with antibiotics. An inflammatory condition, such as sarcoidosis, may be treated with corticosteroids or other anti-inflammatory medications.
Can granulomatous disease be cured?
Treatment. People with CGD take lifelong regimens of antibiotics and antifungals to prevent infections. Injections with interferon gamma, a protein that improves the activity of phagocytes, also may help reduce the number of severe infections. Abscesses need aggressive care that may include surgery.
What is the difference between Mycobacterium tuberculosis and tuberculosis?
Tuberculosis (TB) is caused by a bacterium called Mycobacterium tuberculosis. The bacteria usually attack the lungs, but TB bacteria can attack any part of the body such as the kidney, spine, and brain. Not everyone infected with TB bacteria becomes sick.

What is the function of Phop in tuberculosis?
An essential role for phoP in Mycobacterium tuberculosis virulence Two-component regulatory proteins function in bacteria as sensory and adaptive factors in response to a wide range of environmental stimuli.
