Lobar pneumonia differs from other pneumonias in that it is associated with destructive changes in the lungs. It is a very severe illness with a rapid onset and often-fatal outcome despite early and appropriate antimicrobial treatment.

Patients typically present with an acute onset of high fever and chills; flulike symptoms; and productive cough with an abundant, thick, tenacious, and blood-tinged sputum sometimes called currant jelly sputum.

An increased tendency exists toward abscess formation, cavitation, empyema, and pleural adhesions.

Most pulmonary diseases caused by K pneumoniae are in the form of bronchopneumonia or bronchitis. These infections are usually hospital-acquired and have a more subtle presentation.
