Analysis on the result of blood culture and drug resistance of pathogens isolated from 636 blood samples

Objective To explore the isolated bacteria and their drug resistance from blood culture samples in our hospital.Methods 636 blood samples were cultivated by Bact/Alert3D Automated Blood Culture System and appropriative culture bottles.The positive blood cultures were reinoculated. Then species identification and drug sensitivity tests were performed by the MicroScan A/s-4.Results Among the 636 blood samples, 65 strains of phthogens were isolated (10.22%).40% were gram-positive cocci, 55.4% were gram-negative bacilli, and 4.6% were fungi.Staphylococcus and enterobactericaeae were main pathogens in bacteremia and (or) septicaemia in our hospital . No strains resistant to vancomycin was found in gram-positive cocci. Gram-negative bacilli were highly sensitive to imipenem.But they were resistant commonly to antibiotics used often.Conclusion The kinds of isolated bacteria were complex from the positive blood cultures and their drug-resistance rates were high. More attention should be paid to the detection and surveillance of bacterial resistance in blood culture.
