Timely excision of prophage Φ13 is essential for the Staphylococcus aureus infectious process
Mobile genetic elements play an essential part in the infectious process of major pathogens, yet the role of prophage dynamics in Staphylococcus aureus pathogenesis is still not well understood.

Antibacterial effect of ZnO-B2O3 Matrix Doped with Silver Ions on Gram Positive Bacteria Cultures
In this work, vitreous oxidic structures from the xAg2O×(100-x)[45ZnO55B2O3] system were prepared, with a high content of silver oxide 0≤x≤7 mol%. The start substances were mixed in appropriate proportions and melted at 1230 °C, then undercooled at ...

We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.
