blood cultures

Objective. To compare analytical parameters and sensitivity between BACT/ALERT® 3D 60 and Yunon® Labstar 50. Materials and Methods. The study included 20 species of clinically significant microorganisms isolated from blood (20 strains for each facultative anaerobic species and 10 strains for each aerobic species). For each strain, individual volumes of the inoculation dose were selected with the control of CFU value. In the case of obtaining a stable CFU value in the range 2–10 per 100 µl of bacterial cell suspension, 100 µl of suspension was inoculated into vials with nutrient media for each analyzer, followed by an analysis of the cultivation time, the presence or absence of a growth signal, and average CFU values.
