Among pathogens , the most common pathogens associated with VAP were Pseudomonas aeruginosa ( 3013 %), Acinetobacter baumanii (1115 %), Klebsiella pneumoniae ( 1017 %), Escherichia coli ( 716 %) and S taphylococcus aureus ( 618 %). Their multiple drug2resistance to antibiotics was serious. Drug sensitivity tests indicated that the GNB had lower drug2 resistance to such antibiotics as imipenem , amikacin , piperacillin/ tazobactam , ceftazidime , cefepime , cefoperazone/sulbactam , ciprofloxacin and ticarcillin/ clavulanate. Polymicrobial pathogens were more isolated in late2onset VAP than in early2onset VAP.
