Distribution and Antibacterial Resistance of 326 Strains of Nosocomial Infection Pathogens / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To investigate the distribution and drug resistance of nosocomial infection pathogens. METHODS Statistical methods were used to analyz the data of pathogens origin and drug resistance from 2005 to 2007. RESULTS A total of 326 strains were isolated from 604 nosocomial infection cases (54.0%),from which the Gram-negative bacilli were predominate (44.1%). The isolation rate ot fungi and Gram-positie bacteria was 41.6% and 14.3%,respectiviely. The top three pathogens were the fungi (41.6%),Pseudomonas aeruginosa14.3%,and enterobacter (10.6%). The rate of ampicillin-resistant Escherichia coli was 100%.The isolation rate of MRSA and MRCNS was up to 100.0% and 80.0%. CONCLUSIONS Fungi is common high among pathogens.The emergence of drug-resistant pathogens will continue to be a serious problem,we must take it intimately.
