Tuberculous infection in adults is not a well known entity in our country, despite its epidemiological importance. We have designed an observational study in a homogeneous group of adult civil servants of Catalonia (n = 8,202) from 20 to 54 years old that were submitted to a health examination which included a tuberculin test, in order to study the tuberculous infection in these people and to evaluate the factors associated with this infection.
Results:
The global prevalence of reactivity in tuberculin test was 22.36% and the prevalence of the tuberculous infection was 14.76%. The factors related to the tuberculous infection were the following: age, male sex, background of exposure to sources of contagion, and previous BCG vaccination.
Conclusions:
The prevalence of tuberculous infection in adults has declined, and is currently greater in men than women, among patients who recognize previous contact with a tuberculous patient, and among patients with previous BCG vaccination.

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...
Pulmonary Tuberculosis III
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...
Pulmonary Tuberculosis V
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...
