It most commonly affects hospitalized individuals, particularly critically ill patients receiving mechanical ventilation, as well as immunocompromised hosts and individuals with pre-existing structural lung diseases such as cystic fibrosis or bronchiectasis

It most commonly affects hospitalized individuals, particularly critically ill patients receiving mechanical ventilation, as well as immunocompromised hosts and individuals with pre-existing structural lung diseases such as cystic fibrosis or bronchiectasis Defining clinical features include fever, dyspnea, hypoxemia, and purulent sputum production, frequently complicated by extensive pulmonary infiltrates, tissue cavitations, and a high risk of respiratory failure

Pathophysiologically, the organism employs an array of virulence mechanisms—including elastases, exotoxins, and biofilm formation—to cause extensive epithelial injury, parenchymal necrosis, and marked alveolar inflammation

Defining clinical features include fever, dyspnea, hypoxemia, and purulent sputum production, frequently complicated by extensive pulmonary infiltrates, tissue cavitations, and a high risk of respiratory failure
