Surveillance of antimicrobial susceptibility among bacterial isolates from intensive care unit patients of a tertiary-care university hospital in Iran: 2006-2009.

Background: This study was conducted to determine the antimicrobial susceptibility patterns among common pathogens in the intensive care unit (ICU) of a university hospital in Iran between 2006 and 2009.

Methods: The isolates cultured in appropriate media and antimicrobial susceptibility were determined by disk diffusion tests according to the guidelines of the Clinical and Laboratory Standards Institute.

Results: A total of 606 isolates were recovered from respiratory (70.
