Can you tell me in infants, pneumothorax, pneumatocele, and empyema are frequent complications of pneumonia caused by?

Rare complication: These are very rare and serious complications of pneumonia. First question - is the child immunized? Several organisms can cause this, including Strep pneumoniae and MRSA (methicillin resistant Staph aureus). If an infant is having such serious complications, the immune system will often be checked. Sometimes the bacteria is never recovered because the antibiotics given can alter culture results.
