Abstract:
The tuberculosis of the ear is rare. In most cases, the clinical picture resembles that of a chronic otitis media. The bacteriological exams are seldom positive at the earliest stage of the disease. The two reported cases of this paper illustrate the difficulties of the diagnosis. In the first one, the diagnosis was made although the bacteriological proof could not be obtained, based on other exams. In the second one, it was made on the basis of a positive PCR of the tissues removed during a radical mastoidectomy. The literature on the various clinical aspects of the tuberculosis of the ear is reviewed.

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 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 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...
