Results. A total of 22,075 anaerobic blood cultures were collected from our adult population. Significant anaerobic pathogens were isolated from only 0.14% of these blood cultures. An anaerobic infection could have been suspected in 92% of our patients. Conclusions. Significant anaerobic bloodstream ...
We prospectively examined the utility of obtaining blood cultures through newly inserted intravenous catheters in 99 children who required both a blood culture and placement of an intravenous catheter. Two blood cultures were collected from each patient, one through a freshly inserted intravenous catheter...
Lee et al reported that in order to detect 90% of true bacteraemias, 2 blood culture sets should be taken in a 24 hour period, however to detect > 99% up to 4 blood culture sets may be necessary [30]. Single blood cultures should be discouraged due their lack of sensitivity and ...
We suggest shortening the total incubation time of neonatal blood cultures to a maximum of 3 days. However, blood cultures collected in infants<72 h of age might require a longer incubation time. According to our results, it may be safe to narrow the antimicrobial spectrum to solely target ...
The aim of this study was to determine how long it takes blood culture to become positive using a blood culture system that can be monitored continuously in pediatric patients. Data were collected prospectively on 1,000 positive blood culture results from a tertiary pediatric university hospital fro...
A total of 103,339 sets of blood cultures were collected during the study period. Of these, 12,670 sets were culture-positive. Of these, 594 cases (778 sets) were excluded, because of pending determination in 190 cases and no determination in 404 cases. Eligible blood cultures were collecte...
Geometric mean blood volumes were highest in blood cultures from which S. pneumoniae and C. neoformans were recovered (Table 2). There was also a significant increasing chance of recovering S. pneumoniae with larger blood volumes cultured. Over the range of blood volumes collected in this study,...
To verify cytokine production by PBMC cultures, supernatants were collected on days 3 and 6 and tested for TNF-alpha and RANKL. The data obtained were compared between patients and controls by one-way ANOVA and correlated by Pearson's coefficient. We found a significant increase in osteoclast ...
During this period, 84 of 5,196 (1.6%) fungal blood cultures and 170 of 25,702 (0.6%) bacterial blood cultures were positive for yeast or filamentous fungi. Thirty-seven positive fungal cultures, simultaneously collected, had correspondingly positive bacterial cultures. An additional 15 positive ...
Blood cultures remain the reference standard for the detection of bacteria causing sepsis17. Generally, blood samples are collected and aseptically inoculated in bottles with specific media for aerobic and anaerobic microorganisms. These bottles are then incubated either in manual or in automatic systems...
