Abstract
Objective:To analyse the positive pathogenic bacteria of the blood culture and the alarm time.Method:A total of 2180 blood specimens were collected from April 2010 to April 2012 in our hospital and the specimens were detected by BD BACTEC 9120 automated blood culture system.Analyse the bacterial species and alarm time of the blood specimens in aerobic and anaerobic bottles.Result:282 blood culture positive samples were isolated from the 2180 blood culture samples,which was true positive in 263 cases.The positive rate of the blood culture was 12.1%,which 269 strains of pathogens were isolated,including Gram-positive cocci accounted for 40.1%,gram negative bacilli 57.2%,fungi 2.6%.However the positive rate was just 15.6% only from aerobic bottles and 5.7% only from anaerobic ones,and 20.9% from both of the two bottles.The fastest positive time was 5.02 h, during the test,the number of positive reactions accounted for 69.1% in 24 hours,92.5% in 48 hours,and 97% in 72 hours.The false positive rate was 0.87%, and the false negative rate was 0.52%.Conclusion:Application of both aerobic and anaerobic cultivation detected by BD BACTEC 9120 automated blood culture system can improve the blood culture positive rate,shorten the positive detection time.关键词
