Abstract:
Objective To study the clinical value of the microbe-positive blood culture substance directly detected with Automated Microbiology System,as well as the coincidence rate between the direct method and the regular one(The puremicrobe were detected by WalkAway 40 after reiuoculated,and applied to antibiotic susccptibility tests).Methods To mix the positive blood culture liquid with the special inoculum liquid,then inoculate with the special identify panel to take bacterium identifying and antibiotic susceptibility testing on the system directly.At last,to contrast the result to the regular one.Results The coincidence rate between 74 samples of the positive blood culture substance on the system directly and the regular method was more than 94.4%.And the coincidence rate of antibiotic susceptibility test between the direct method and the regular one was more than 95%.And the results of the direct method could be acquired 24h earlier than those of the regular one.Conclusion The direct antibiotic susceptibility test method reduces the testing time,and get more time for bacteria treating.Meanwhile,the coincidence rate between the regular method and the direct one is high.
