Surveillance of dominant bacterial species isolated in our hospital from March 2005 to July 2007 was examined and the resistance rate was determined. PISP and RSP were isolated at high frequencies of 62.0-85.7%. MRSA and BLNAR Haemophilus influenzae were subsequently isolated at frequencies of 30.2-58.6% and 4.9%-35.5%, respectively. The frequencies of other resistant bacteria were under 5%. ESBL-producing Escherichia coli was isolated at a frequency of 4.4%. Half of the ESBL-producing strains were isolated from outpatients, and 6.8% of the strains were present at the time of hospital admission. The findings of this surveillance indicate that it is necessary to pay careful attention to the trends of resistant bacteria such as PRSP, MRSA, BLNAR, and ESBL-producing strains. S. aureus and S. pneumoniae infections require prevention and treatment as MRSA and PRSP, respectively, until the findings of antimicrobial susceptibility tests are known.
