Identification of Pathogens and Drug Sensitivity Analysis 415 Sputum Samples / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To understand the bacterial spectrum distribution of sputum among the lung infection patients in our hospital and their resistance mechanisms for the reasonable clinical application of antibiotics to effectively prevent the occurrence of nosocomial infections. METHODS The pathogens isolated from the sputum of patients were identified with pathogen micro-biochemical identification code and the commonly used antibiotics were detected by drug sensitivity tests. RESULTS From 415 samples of the sputum,537 strains were detected out,from them Gram-positive cocci accounted for 70.8%,Gram-negative bacteria accounted for 28.1%,and Candida albicans accounted for 1.1%;MRSA was in 18 strains and ESBLs 6 strains. CONCLUSIONS It is important to sputum culturing for lung infection patients and determining the pathogen species and in their drug susceptibility results,the in order to rationally use the antibiotics and enhance the effectiveness of treatment.
