Setting:
Galicia, Spain.
Objective:
To describe the epidemiological evolution and characteristics of tuberculosis (TB) in Galicia over a 10-year period from 1996 to 2005.
Design:
A retrospective, descriptive and observational study was conducted, based on data obtained from the Galicia Tuberculosis Registry.
Results:
The incidence of TB in Galicia fell from 72.3 cases per 100000 population in 1996 to 37.7/100000 in 2005, resulting in an average annual decrease of 7.0%. In 2005, 51.6% of cases were aged 15-44 years, 61.6% were men, and 59.2% were exclusively pulmonary. No cavitary lesions were found in 63.4%; 50.3% of pulmonary TB cases were sputum smear-positive, and a positive culture was found in 77.3%; 4.4% were human immunodeficiency virus positive, 3.5% were drug users and 3% were immigrants. At least one contact was studied in 80% of smear-positive index cases. The treatment success rate was close to 90%.
Conclusions:
The annual incidence of TB in Galicia has fallen progressively since the TB programme was implemented; it is nevertheless still higher than in other regions of Spain and neighbouring countries, and greater progress in TB control needs to be made.

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...

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.
