Out of 200 VAP cases, 111 grew bacterial pathogens that were further divided into Group I and Group II bacteria.
Group I: pathogens that did not include any of the Acinetobacter, Stenotrophomonas, or Pseudomonas species.
Group II: pathogens that included any of the Acinetobacter, Stenotrophomonas, or Pseudomonas species.
