Abstract:
The arrest of Mycobacterium tuberculosis phagosome maturation in infected macrophages is a phenomenon of dual significance both for the pathogenesis of tuberculosis and as a model system to study interference of microbes with membrane trafficking and organelle biogenesis in host cells. Among other factors, compartment-specialized regulators of vesicular trafficking and other parts of membrane fusion machinery are likely to play a role in these processes. Here we summarize the emerging view of mycobacterial phagosome maturation arrest in the context of the dynamic processes of intracellular membrane trafficking.

Pulmonary Tuberculosis II
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Phagocytosis
The objective of phagocytosis is often destruction. Cells use phagocytosis to eliminate unwelcome visitors, like pathogens (e.g., viruses and bacteria). Many immune system cells, including...

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
