ABSTRACT
Stationary incubation of aerobic blood cultures was compared with intermittent shaking in aerobic Vacutainer 2630 bottles with agar slants during the first 24 h, and was simultaneously compared with the continuously shaken aerobic Bactec 6A bottles as a reference system. Intermittent shaking did not significantly increase or decrease the seven days yield of the Vacutainer bottles as compared with the continuously agitated Bactec 6A bottles. When one of 604 paired Vacutainer bottles was agitated for eight h and the other incubated stationary, the speed of growth detection was significantly greater in the agitated bottle (p less than 0.001), but significantly less than with continuously agitated Bactec 6A bottles (p less than 0.001). Agitation for 14 h showed the same pattern of detection speed. These results suggest that it is desirable initially to agitate aerobic blood cultures either intermittently or continuously.
