[Immune reactivity in pneumoconiosis and coniotuberculosis in machine builders]
Abstract:
Immune status was examined in 231 patients facing pneumoconiosis and coniotuberculosis so as to observe a dependence on pneumoconiosis type (silicosis, electric welder's pneumoconiosis), severity of the process, activity of tuberculosis. Markedly changed T and B immunity, having already appeared at initial stage of the disease, were revealed. Those changes due to the tuberculosis activity were characterized by lymphocytosis, marked functional immaturity of T lymphocytes, depressed B lymphocytes count, elevated serum Ig level.

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 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...

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