Staphylococcal pneumonia

Staphylococcal pneumonia is an acute, severe lower respiratory tract infection primarily caused by *Staphylococcus aureus*, involving either methicillin-susceptible or methicillin-resistant strains It affects pediatric, elderly, and immunocompromised individuals in community settings—frequently manifesting as a secondary infection following viral respiratory illnesses such as influenza—as well as hospitalized and mechanically ventilated patients Clinically, it presents with high fever, cough, dy...
