Background: Ventilator associated pneumonia (VAP) occurs after 48 hours in mechanically ventilated patients. They are a significant cause of morbidity and mortality.

Materials and Methods: 100 patients were selected for the study. The details of the patients were collected. The tracheal aspirates were processed and the pathogens identified using standard protocol. Antimicrobial sensitivity testing was done.

Results: The incidence of VAP was 36% .The incidence of monomicrobial and polymicrobial VAP was 55.56% and 44.44%. Acinetobacter baumanii was isolated most commonly in both types of VAP. More than 80% of isolates were multidrug resistant. There was prolonged duration of mechanical ventilation and hospital stay in VAP patients.

Conclusion: Proper preventive measures should be undertaken to reduce the rates of nosocomial pneumonia by multidisciplinary approach.
