Pulmonary tuberculosis

Pulmonary tuberculosis is a contagious bacterial infection of the respiratory system caused by Mycobacterium tuberculosis, primarily affecting the lung parenchyma Transmission occurs through inhalation of aerosolized droplets, inciting a localized host immune response characterized pathologically by granulomatous inflammation, caseating necrosis, and potential cavitary formation The clinical disease may manifest shortly after initial exposure as primary infection or arise years later via reactiv...

Pulmonary tuberculosis is a contagious bacterial infection of the respiratory system caused by Mycobacterium tuberculosis, primarily affecting the lung parenchyma

Transmission occurs through inhalation of aerosolized droplets, inciting a localized host immune response characterized pathologically by granulomatous inflammation, caseating necrosis, and potential cavitary formation The clinical disease may manifest shortly after initial exposure as primary infection or arise years later via reactivation of a dormant, latent infection

Transmission occurs through inhalation of aerosolized droplets, inciting a localized host immune response characterized pathologically by granulomatous inflammation, caseating necrosis, and potential cavitary formation

Defining clinical features typically include a persistent productive cough, hemoptysis, pleuritic chest pain, fever, drenching night sweats, fatigue, and unintended weight loss
