Overview
The majority of cases related to various gram-negative bacilli (52%) and S. aureus (19%). Others are Haemophilus spp. (5%). In the ICU results were S. aureus(17.4%), P. aeruginosa (17.4%), Klebsiella pneumoniae and Enterobacter spp. (18.1%), and Haemophilus influenzae (4.9%). Viruses -influenza and respiratory syncytial virus and, in the immunocompromised host, cytomegalovirus- cause 10-20% of infections.
Etiological agents [1]
Aerobic gram negative pathogens
- Commonly polymicrobial
- Common microbial agents include:
Gram-positive pathogens
- Staphylococcus aureus
- Methicillin resistant staphylococcus aureus (common in patients with diabetes mellitus, head trauma, and in ICU)
