"Streptococcus pneumoniae, Haemophilus influenzae and Staphylococcus aureus are "typical" pneumonias, however the definition of "atypical" pneumonia is inconsistent. So-called "atypical" pneumonias are a significant cause of outbreaks and pandemics."
"Pulmonary inflammation may be airway and interstitial predominant with radiographic features of bronchopneumonia, peribronchial opacity, patchy reticulonodular or hazy opacities. These opacities are especially seen in the lower lobe(s) or parahilar lung 5. Subsegmental and sometimes segmental atelectasis from small airway obstruction may occur. The radiographic features are often more extensive than expected from the clinical features."

"Pneumonia can be caused by bacteria, viruses or fungi and remains a leading cause of death globally. The causative agent depends on local pathogens and is not identified in about 60% of pneumonias."
