Distribution Characteristics and Drug Resistance Analysis of Pathogens from 2005 to 2007 / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To investigate the uses of antibacterials,the characteristics of bacterial distribution and the drug resistance and provide a foundation for reasonable application of antibacterials.METHODS Germs isolation and cultivation were carried out according to National Clinical Testing Operation Procedures(2nd edition).Germs definition and resistance test were carried out by using VITEK 2 Compact microbiological assay system.Statistical analysis was processed by using WHONET 5.4.RESULTS Totally 7815 strains of bacteria were isolated from clinical samples,most of which were Gram-negatives(G-)(58.0%,56.3% and 59.5%,respectively in the 3 years).The tendency of Gram-positives(G+) didnot charee obviously(about 20%).Theresistance were increasing.The resistance rate of Staphylococcus aureus was more than 70.0 % to the most antibacterials.Up to now,there was no vancomycin-resistant isolate.CONCLUSIONS We should use antibacterials reasonably and efficiently to delay and control drug resistance,according to the susceptibility test.
