Which organism type accounts for the majority of VAP?

Explanation:
Ventilator-associated pneumonia is driven mainly by bacterial pathogens. The endotracheal tube and the ICU environment disrupt normal airway defenses and promote colonization by bacteria from the patient’s own flora and hospital sources. The most common culprits are Gram-negative rods such as Pseudomonas, Klebsiella, and Enterobacterales, along with Staphylococcus aureus. Viruses and fungi do appear in some cases, but they account for a smaller portion of VAP. So the organism type most often responsible for VAP is bacteria.
