A 53-year-old with a history of chronic alcohol abuse presents with a productive cough and fever. His symptoms started one week ago. On examination, he has diffuse rales in all lung fields. A CXR reveals patchy infiltrates in all lung fields and a 5 cm area of consolidation in the lower right lobe that has an air-fluid level. Which of the following infectious agents is likely to be the cause of his pulmonary disease?
A. Mycobacterium tuberculosis
B. Mycoplasma pneumoniae
C. Candida species
D. Staphylococcus aureus
E. Influenza A virus
D) Staph aureus since it causes bronchopneumonia (patchy infiltrates) and abscess (air-fluid level) since he is an alcoholic he probably aspirated the organism.
