Neonatal Sepsis And Antibiotic Sensitivity Patterns At A South African Tertiary Nursery – Evolution Over A 15 Year Period
… nursery in Cape Town. Methods Retrospective blood culture data for 12 months were collected at three time points over a 15-year period. Blood cultures from 2004, 2013 and 2017 were analysed. All neonates with growth on blood cultures were included. Results During 2004 a total of 817 (43.3% of …

Reducing blood culture contamination in the emergency room
Purpose/Objectives: When blood culture contamination in emergency departments is above 3%, it is associated with adverse patient outcomes, inappropriate antibiotic use, and increased hospital costs. In a large, Midwestern, level I trauma hospital, there is a blood culture contamination (BCC) rate …

Sphingosine-1-phosphate in mast cell-mediated allergic responses
… marrow-derived progenitors that circulate in the blood as immature precursors. Mast cell progenitors are likely to encounter the serum-borne bioactive sphingolipid metabolite, sphingosine-1-phosphate (S1P), during migration to target tissues. Mast cells developed from human cord blood-derived …

Extraction of Leucocidin From Staphylococci and Its Practical Application in the Diagnosis of Septicemia
… phagocytosis after aseptic transfer of whole blood to a suitable liquid media has been a probable source of false negative blood culture results. This idea is due to the fairly high percentage of suspected septicemia patients who have given negative results with many blood cultures. It also …

BACTERIA ANALYSIS BY USING A SUPERVISED MACHINE LEARNING ALGORITHM BASED ON DROPLET MICROFLUIDICS
… Up to 5 days of incubation are needed for blood cultures, the majority of bacteria being detected after 12–48 h. Therefore, fast and simple techniques are required for rapid bacterial cell detection and quantification. By using droplet microfluidics and a machine learning algorithm, the …

The Pneumococcus Urinary Antigen Test Kit: Use in the laboratory for the presumptive diagnosis of pneumococcal bacteraemia
… using a urine antigen test directly on selected blood cultures with appropriate Gram stain results, immediately after signalling positive for the rapid identification of S. pneumoniae bacteraemia. Method: We collected 212 blood cultures that had signalled positive with an automated blood culture …
