Abstract: Objective To investigate the distribution and drug resistance of pathogen in blood culture from 2014 to 2015.Meth-ods 1 260 blood specimens were incubated in our hospital,the positive samples were isolation and identification and the drug resist-ance was analyzed.Results 153 strains of bacteria were isolated from 1 260 blood specimens,and the positive rate was 12.1%. Escherichia coli and Klebsiella pneumonia were the main pathogens in gram negative bacilli,coagulase negative Staphylococci and Staphylococcus aureus were the main pathogens in gram positive cocci,Imipenem and ertapenem were the most effective antibiotics (100.0%)to Escherichia coli and Klebsiella pneumonia,the gram-positive cocci were sensitve to Vanconmycin,linezolid and tigecy-cline.Conclusion Drug resistance of isolated pathogen in blood cultures is very serious.Monitoring the change of pathogens and trends of drug resistance is very important in guiding the clinical use of drug.
