COMPARISON OF LYSIS-CENTRIFUGATION WITH LYSIS-FILTRATION AND A CONVENTIONAL UNVENTED BOTTLE FOR BLOOD CULTURES JOURNAL OF CLINICAL MICROBIOLOGY Gill, V. J., ZIERDT, C. H., Wu, T. C., Stock, F., Pizzo, P. A., MACLOWRY, J. D. 1984; 20 (5): 927-932

Abstract

Evaluation of a commercially available lysis-centrifugation blood culture system (Isolator, DuPont Co., Wilmington, Del.) and a lysis-filtration blood culture system for 3,111 cultures showed that both methods had comparable recoveries (73 and 68%, respectively) of significant aerobic and facultatively anaerobic isolates. The unvented conventional blood culture bottle had a recovery rate of 59%. Although the lysis-centrifugation and lysis-filtration systems had comparable recoveries of pathogens, the lysis-centrifugation system had the advantage of having colonies immediately available for further testing. The contamination rate with the lysis-centrifugation system was 3%, compared with 6% with the lysis-filtration system and 0.4% with brain heart infusion.
