  1. 15 Απρ 2024 · Follow-up blood cultures — Blood cultures should be drawn every 24 to 48 hours until clearance is demonstrated. Persistent S. aureus bacteremia despite appropriate antibiotic therapy is prognostically important.

  2. Labi et al. (2016) showed a high number of positive blood culture samples (21.9%) among neonates, and the significant pathogens were CoNS. Nanoukon et al. (2017) obtained similar results in Benin, where S. haemolyticus and S. epidermidis were identified as the most frequently isolated pathogens.

  3. 17 Ιαν 2024 · Various approaches for early identification of bacteria from a positive blood culture include Gram staining, conventional biochemical assay, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, PCR, and nanoparticle probe technology.

  4. Abstract. We compared two real-time PCR assays (both by the use of melting curve analysis) for their ability to identify Staphylococcus species directly from 200 positive blood culture bottles. The PCR assays correctly identified 83% to 94% of the Staphylococcus isolates to species clusters.

  5. 20 Αυγ 2024 · The rapid and accurate identification of Staphylococcus aureus (SA) in blood cultures is vital for timely and appropriate clinical intervention. This study introduces the “STAPH score,” a novel semi-quantitative scoring system that combines Gram stain morphology and time to positivity.

  6. Staphylococcus aureus is an opportunistic pathogen that normally colonizes the human anterior nares. At the same time, this pathogen is one of the leading causes of life-threatening bloodstream infections, such as sepsis and endocarditis.

  7. Staphylococcus aureus bacteremia (SAB) is a relevant finding which prompts a thorough diagnostic work-up. Follow-up blood cultures (BC) are essential in this work-up. We investigate the probability of detecting an ongoing bacteremia after initiation of active therapy according to the number of BC taken at key time points.
