Background And Objectives:
Mitochondrial DNA has a unique role in ATP production and subsequent mitochondrial reactive oxygen species (ROS) production in eukaryotic cells and there is a potential role for ROS and oxygen burst against Mycobacterium tuberculosis, an intracellular pathogen. This study aimed to determine whether the frequency of different mitochondrial haplogroups was significantly different in patients with tuberculosis (TB) compared with a normal population.
Methods:
Mitochondrial DNA haplogroups M, N, J and K were studied by PCR-restriction fragment length polymorphism and sequencing. Cases were 54 patients with confirmed smear positive pulmonary TB. Controls were 256 healthy persons.
Results:
There were no statistically significant differences between those with TB and the control group.
Conclusions:
There was no statistically significant association between mtDNA haplogroups and the presence of TB infection.

Pulmonary Tuberculosis III
The first classification is based on the development of the disease, and it includes the following categories:
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.

Pulmonary Tuberculosis IV
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
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...
