Article Synopsis
  • Cyclic di-AMP is crucial for Gram-positive bacteria, helping to regulate osmotic pressure by interacting with specific protein domains related to potassium and osmolyte uptake.
  • The CbpB protein from Group B Streptococcus has a strong binding affinity for c-di-AMP, and its crystal structure reveals how it recognizes c-di-AMP and undergoes significant changes when binding occurs.
  • Deleting the cbpB gene negatively impacts bacterial growth under low potassium conditions, likely due to reduced levels of ppGpp resulting from disrupted interaction between CbpB and the enzyme Rel.

Objective: Vancomycin, a commonly used antimicrobial, has a narrow therapeutic index; therefore, Therapeutic Drug Monitoring (TDM) is required. Although the Electronic Medical Record (EMR) may improve patient care, without appropriate optimization, it can contribute to incorrectly drawn vancomycin levels. For medication administration, nurses utilize the Medication Administration Record (MAR) for medication administration documentation and medication workflow guidance.

Central venous catheter (CVC) vascular access is common among patients on hemodialysis. CVC use carries a substantial risk of central line-associated bloodstream infections (CLABSIs), costly events that place patients at a high risk of mortality. Our hospital and dialysis organization developed a cooperative strategy to reduce the rate of CLABSI among hospitalized patients on hemodialysis with a CVC.

Cyclic nucleotides are universally used as secondary messengers to control cellular physiology. Among these signalling molecules, cyclic di-adenosine monophosphate (c-di-AMP) is a specific bacterial second messenger recognized by host cells during infections and its synthesis is assumed to be necessary for bacterial growth by controlling a conserved and essential cellular function. In this study, we sought to identify the main c-di-AMP dependent pathway in Streptococcus agalactiae, the etiological agent of neonatal septicaemia and meningitis.

Cyclic di-AMP (c-di-AMP) is a bacterial signaling nucleotide synthesized by several human pathogens. This widespread and specific bacterial product is recognized by infected host cells to trigger an innate immune response. Detection of c-di-AMP in the host cytosol leads primarily to the induction of type I interferon via the STING-cGAS signaling axis, while being also entangled in the activation of the NF-κB pathway.
