Analysis on Distribution and Antibacterial Resistance of Nosocomial Infection Pathogens of ICU Inpatients in a Hospital / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To investigate the distribution and drug resistance of nosocomial infection pathogens.METHODS The data of pathogen′s origin and antibacterial resistance of Intensive Care Unit(ICU) inpatients from Apr 2008 to Mar 2009 in a Hospital were analyzed.RESULTS There were 226 strains pathogens isolated from 116 nosocomial infection cases,from which the Gram-negative bacteria were predominate(63.27%).The resistance rates of Acinetobacter baumannii was the highest in Gram-negative bacteria,more than 70% isolates resistant to almost antibacterial.The main Gram-positive bacteria were Staphylococcus aureus,and the rate of meticillin-resistant S.aureus(MRSA) was 41.3%.All S.aureus were sensitive to vancomycin and Linezolid.CONCLUSIONS To control the antibacterial resistance of pathogens and decrease the nosocomial infection,it is important to strengthen the appropriate use of antibiotics.
