Blood Culture Samples Pathogen Species Distribution and Sensitivity Analysis

OBJECTIVE To investigate the distribution of pathogenic bacteria in blood culture and their drug-sensitivity in our hospital in the past year.METHODS The blood samples were cultivated in the BacT/Alert 3D system and the isolated colonies were identified by the VITEK32 system or traditional routine procedures.The K-B method was carried out for the drug-sensitivity festing.RESULTS From the 716 blood samples received,we identified 109 strains of pathogens in which Gram-positive cocci accounted for 50.46%,Gram-negative bacilli for 44.04% and fungi for 5.5%.CONCLUSIONS There are many kinds of pathogens identified from blood culture and they have high resistance to many antibiotices.It is very important for doctors to get the results of blood culture in time in order to give the patients correct antibiotic therapy and to improve the cure rate and to control cross-infection in hospials.
