Genome sequences of 14 Firmicutes strains isolated from the human vagina [PDF]

, 2016
Research on vaginal infections is currently limited by a lack of available fully sequenced bacterial reference strains. Here, we present strains (now available through BEI Resources) and genome sequences for a set of 14 vaginal isolates from the phylum ...

On the closure of the completely positive semidefinite cone and linear approximations to quantum colorings [PDF]

, 2015
We investigate structural properties of the completely positive semidefinite cone $\mathcal{CS}_+^n$, consisting of all the $n \times n$ symmetric matrices that admit a Gram representation by positive semidefinite matrices of any size. This cone has been

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

Nature 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 ...

Machine learning model for the prediction of gram-positive and gram-negative bacterial bloodstream infection based on routine laboratory parameters

BMC Infectious Diseases, 2023
Background Bacterial bloodstream infection is responsible for the majority of cases of sepsis and septic shock. Early recognition of the causative pathogen is pivotal for administration of adequate empiric antibiotic therapy and for the survival of the ...

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

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

Scientific 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

Gut 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.
