Overview
Lung abscess is commonly caused by bacterial infections and these include bacteroides, peptostreptococcus and prevotella.
Causes
Life Threatening Causes
Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated.
Microbiology
- About 90% of the lung abscess is caused by polymicrobial infection.[1] [2]
- Anaerobes are the predominant pathogens involved in primary lung abscess, followed by Streptococcus pneumoniae.
- Klebsiella pneumoniae is the more commonly seen in alcoholics.[3]
- Staphylococcus aureus is the most common pathogen responsible for lung abscess in children with cystic fibrosis.[4]
The following table elaborates the most common etiological pathogens responsible for lung abscess [5]
