AI Article Synopsis

  • Antibiotic treatment for deep-seated staphylococcal infections tied to orthopedic implants often fails, highlighting a challenge in these cases.
  • Standard antibiotics like semi-synthetic penicillins and cephalosporins work well as preventive measures but struggle to treat existing infections effectively.
  • The mechanisms causing this treatment failure, including bacterial tolerance to antibiotics, are not fully understood, suggesting a need for further research.

Article Abstract

Antibiotic therapy for deep-seated staphylococcal infections, especially when they are associated with artificial devices used for orthopedic surgery is often associated with failure. Standard anti-staphylococcal bactericidal antibiotics, such as semi-synthetic penicillins, cephalosporins, or glycopeptides, are effective when given prophylactically in clinical conditions or experimental trials of implant-related infections. However, the efficacy of all anti-staphylococcal agents is seriously diminished on already established implant-related deep-seated infections, which then frequently require surgical implant removal to obtain a cure. The failure of antibiotic therapy to cure established staphylococcal foreign-body infections may arise in part from a broad-spectrum phenotypic tolerance expressed in vivo to different classes of antimicrobial agents. The molecular and physiological mechanisms of this in vivo tolerance remain poorly understood.

Gallium, a trace metal not found in its elemental form in nature, has garnered significant interest as a biocide, given its ability to interfere with iron metabolism in bacteria. Consequently, several gallium compounds have been developed and studied for their antimicrobial properties but face challenges of poor solubility and formulation for delivery. Organizing the metal into three-dimensional, hybrid scaffolds, termed metal-organic frameworks (MOFs), is an emerging platform with potential to address many of these limitations.

is a highly multidrug-resistant pathogen resistant to almost all classes of antibiotics; new therapeutic strategies against this infectious agent are urgently needed. Shikimate kinase is an enzyme belonging to the shikimate pathway and has become a potential target for drug development. This work describes the search for Food and Drug Administration (FDA)-approved drugs and natural compounds, including gallic acid, that could be repurposed as selective shikimate kinase inhibitors by integrated computational and experimental approaches.

is a pathogenic bacterium that can infect humans and animals, yet the role of its outer membrane vesicles (OMVs) in mediating pathogenicity remains underexplored. This study evaluated the effects of linoleic acid (LA) and stearic acid (SA) on quorum sensing (QS)-mediated violacein production, biofilm formation, and OMV biogenesis in . Our findings revealed that 2 mM LA and 1 mM SA effectively quench QS, leading to a significant reduction in violacein production, biofilm formation, and OMV biogenesis.
