Pulmonary tuberculosis apparently caused by the avian tubercle bacillus
Abstract:
Avian tubercle bacilli were repeatedly isolated from the sputum of a 65-year-old man who had cavitary disease in the upper lobe of the right lung. The clinical picture resembled that of pulmonary tuberculosis caused by the human type of tubercle bacilli, but the response to antituberculosis chemotherapy was unsatisfactory and the patient's sputum remained positive. The bacilli were markedly pathogenic to chickens and rabbits but failed to produce progressive disease in guinea pigs. This is in accord with the properties of tubercle bacilli of the avian type.

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...

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...
