 # Organism most commonly seen in lung abscesses is: 
A. Candida albicans 
B. Herpes zoster virus 
C. Oropharyngeal flora 
D. Staphylococcus aureus


(PSC KOSHI 2081)



The correct answer is C. Oropharyngeal flora. 

Lung abscesses are typically caused by aspiration of bacteria from the oropharyngeal flora. This flora includes a mix of aerobic and anaerobic bacteria normally found in the mouth and throat. When these bacteria are aspirated into the lungs, they can cause an infection leading to a lung abscess.

While the other options listed can cause infections in the lungs, they are not the most common cause of lung abscesses:

Candida albicans (A): This fungus is a common cause of opportunistic infections, but it is not the most common cause of lung abscesses.
Herpes zoster virus (B): This virus causes shingles and can rarely lead to lung complications, but it is not a common cause of lung abscesses.
Staphylococcus aureus (D): While this bacterium can cause pneumonia and other lung infections, it is not the most common cause of lung abscesses.
