Abstract:
We report a 16-year-old previously healthy boy who presented with a 6-week history of fever, anorexia, weight loss, and respiratory distress. The chest radiograph showed bilateral upper infiltrates and cavitations indistinguishable from Mycobacterium tuberculosis infection. He was actually infected with M. kansasii. Treating Mycobacterium in an immunocompetent child requires multiple antimycobacterial drugs, including isoniazid, rifampicin, and ethambutol for at least 12 months after negative sputum culture.

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.
