Overview
Lung abscess is commonly caused by bacterial infections and these include bacteroides, peptostreptococcus and prevotella. Most of the lung abscess is caused by polymicrobial organisms,of which anaerobes dominate. Less common include nocardia, actinomyces and fungi .
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]
