The Centers for Disease Control and Prevention (CDC) criteria were used to classify the blood culture results. The contamination rates were illustrated with a g-chart. Results: We identified 331 false-positive blood cultures, among 32,961 cultured specimens; yielding a contaminatio...
Perform a venipuncture; collect the specimen in the appropriate blood culture collection container. The high risk for contamination of blood cultures by skin and other flora can be dramatically reduced by careful preparation of the puncture site and collection containers before specimen collection. ...
The diagnosis of a BSI mandates that a specimen of blood be drawn, that it subsequently be cultured positive and that contamination be ruled out [2]. In surveillance, the detected occurrence of BSI will be related to the rate of culturing [3–5]. On the one hand, if too few cultures ...
1. What was the size of the global blood culture test market in 2024? The global blood culture test market was valued at USD 5.5 Billion in 2024. 2. What is the expected growth rate of the global blood culture test market during 2025-2033? We expect the global blood culture test market...
Blood cultures were evaluated by a physician (RL and DLC) and those with one set of two blood samples for CoNS were further evaluated for time to positivity and those with one out of four bottles positive for CoNS were considered contamination and excluded, resulting in the removal of 89 (...
Delayed entry of blood culture bottles is frequent in consolidated laboratories. A retrospective study evaluated time from insertion to detection and total detection time as a function of preincubation time, and we prospectively looked for false negative
After sorting, the purity of the three populations was assessed both for contamination by lymphocytes and other DC subsets by flow cytometric analysis and were typically > 95% pure (Fig. 1B). Notably, we observed that the cDC express different levels of CD172a (Fig. 1B). Staining...
Culture-dependent approaches have also confirmed the presence of Serratia in this mosquito species [45–48]. The variable nature of infection in the field could be due to the presence or absence of this bacterium in the local aquatic env...

In principle, we performed surveillance blood culture weekly for these patients. Sixteen patients (21.6%) developed definite BSI. In a multivariate analysis, a myeloablative conditioning regimen, high-risk disease status at allo-SCT, and the presence of a central venous catheter at the initiation ...
