Bacteriological profile of early and late onset ventilator associated pneumonia

The present study showed GNB as the most common organism isolated. Pseudomonas spp (24.6%), followed by Klebsiella spp (22.8%), Acenitobacter spp (12.3%), former being predominant in early onset variety & the latter in the late onset VAP. Other organisms like E.coli, Citrobacter species, Proteus species, staphylococcus aureus and CONS are isolated in their decreasing frequency. Most of the organisms are resistance to Beta lactams and cephalosporins but sensitive to carbepenems.
