Abstract:
A 71-year-old man with a history of chronic obstructive pulmonary disease (COPD) and silicosis was referred to our hospital for an evaluation of dyspnea. A progressively enlarging cavity found in the patient's left lower lung was associated with a worsening respiratory status. One year after the initial referral, the patient was diagnosed with nontuberculous mycobacterial (NTM) infection. We herein report the case of a patient with a mixed infection of M. kansasii, M. avium complex and M. abscessus, the various organisms having been isolated in succession. Recognizing a diagnosis of mixed pulmonary NTM infection is therefore crucial in patients with underlying diseases.

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.

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...
