Value of anaerobic blood culture in 4018 blood cultures samples

OBJECTIVE To evaluate the clinical significance of anaerobic blood culture bottles in the detection rate of the pathogens and the time of positive reports.METHODS The blood culture was statistically analyzed for 4018 patients with suspected blood stream infections submitted from Jan 21011 to Mar 2012.RESULTS The detection rate of the aerobic bottles and anaerobic bottles submitted at the same period was 14.11%,only higher than 9.26% of the aerobic bottles,the difference was statistically significant(P0.05);on detecting Escherichia coli and Enterococcus,anaerobic blood cultures bottles(306,630 min)needed significantly shorter time than did the aerobic blood bottles(612,810 min),(P0.05);2.42% of the cases only were determined positive in anaerobic blood cultures bottles while both aerobic and anaerobic bottles were obtained,the anaerobic blood cultures could increase 17.11% of the isolation rate of the pathogens causing blood stream infections.CONCLUSION To increase the anaerobic bottle blood cultures may significantly increase the isolation rate and shorten the report time,it is necessary for the hospital to intensify the submission of the anaerobic blood culture bottles.
