Background:
To know from two different criteria, CDC's and Spanish national consensus (NC), the tuberculin conversion rate and the factors associated to this phenomenon.
Patients And Methods:
A retrospective cohort study was designed over 475 health care workers. Risk factors were identified by using a Cox's proportional hazards model for each criteria.
Results:
Not being vaccinated with BCG appears to be a risk factor in NC model 5.37 (CI 95%: 2.21-13.00) and does not in CDC. There was a difference of 45% between both incidence density rates.
Conclusions:
We did not find a total concordance between the results from the two models.

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.

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...
