Antibacterial effect of ZnO-B2O3 Matrix Doped with Silver Ions on Gram Positive Bacteria Cultures

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
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 ...

Constitutive activation of two-component systems reveals regulatory network interactions in Streptococcus agalactiae

open access: yesNature Communications
Bacterial two-component systems (TCSs) are signaling modules that control physiology, adaptation, and host interactions. A typical TCS consists of a histidine kinase (HK) that activates a response regulator via phosphorylation in response to ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
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 ...

Antimicrobial and anti-biofilm activity of Hypericum brasiliense extract and its fractions on Staphylococcus of canine origin

open access: yesScientific Reports
The growing resistance to antimicrobials, partly due to the ability to form biofilms, poses a challenge for developing new antimicrobial agents. This study assessed the antimicrobial and antibiofilm activity of Hypericum brasiliense extract, Japonicin ...

Induction of intercrypt goblet cells upon bacterial infection: a promising therapeutic target to restore the mucosal barrier

open access: yesGut Microbes
Intestinal mucins play a crucial role in the mucosal barrier, serving as the body’s initial defense against microorganisms. However, how the host regulates the secretion and glycosylation of these mucins in response to bacterial invasion remains unclear.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

open access: yesFEBS Letters, EarlyView.
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.
