Effect of Inoculum Size on Detection of Candida Growth by the BACTEC 9240 Automated Blood Culture System Using Aerobic and Anaerobic Media
Open accessAbstract
Simulated candidemia was produced with 20 Candida isolates at three inoculum sizes (100, 10, and 1 CFU/ml of blood). Growth detection was better with larger inocula. The time to growth detection was shorter with larger inocula. Inoculum size does effect Candida growth detection and time to detection in BACTEC 9240 automated systems.

Detection of candidemia by blood culture often takes more than 24 hours, and for species such as Candida glabrata the time to positive culture can be even longer.
“Furthermore, detection of candidemia by blood culture often takes more than 24 hours.For certain species, such as C glabrata, the time to positive culture can be even longer.[56][57][58][59][60]”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
