The Subgingival Host–Microbial Landscape in Mothers With Periodontitis and Their At‐Risk Offspring

Journal of Clinical Periodontology, Volume 53, Issue 2, Page 201-213, February 2026.
ABSTRACT Aim To evaluate the subgingival proteome and microbiome of mothers with periodontitis and their offspring, thereby assessing signatures of periodontal diseases. Methods Forty participants in four groups were included: mothers with periodontitis and their offspring, as well as periodontally healthy mothers and their offspring.

Interaction of nuclease colicins with membranes: insertion depth correlates with bilayer perturbation. [PDF]

PLoS ONE, 2012
Protein transport across cellular membranes is an important aspect of toxin biology. Escherichia coli cell killing by nuclease colicins occurs through DNA (DNases) or RNA (RNases) hydrolysis and to this end their cytotoxic domains require transportation ...

Effects of Lipopolysaccharide Core Modulation on Outer Membrane Protein Function and Virulence in Pectobacterium carotovorum

Molecular Plant Pathology, Volume 27, Issue 1, January 2026.
The LPS core is critical for virulence in Pectobacterium carotovorum, as its truncation disrupts outer membrane protein assembly, reducing protease secretion, motility, and soft rot symptoms. ABSTRACT Lipopolysaccharide (LPS) is a critical component of the bacterial outer membrane, which serves as a permeability barrier and site for sensing ...

Colicins and Salmocins – New Classes of Plant-Made Non-antibiotic Food Antibacterials

Frontiers in Plant Science, 2019
Recently, several plant-made recombinant proteins received favorable regulatory review as food antibacterials in the United States through the Generally Recognized As Safe (GRAS) regulatory procedure, and applications for others are pending.

Methyltransferase as Antibiotics Against Foodborne Pathogens: An In Silico Approach for Exploring Enzyme as Enzymobiotics

Frontiers in Genetics, 2022
The development of resistance in microbes against antibiotics and limited choice for the use of chemical preservatives in food lead the urgent need to search for an alternative to antibiotics. The enzymes are catalytic proteins that catalyze digestion of

Mode of Action of Colicin A [PDF]

Journal of Bacteriology, 1969
Colicin A acting on sensitive cells of Escherichia coli inhibits a number of energy-requiring cellular functions. It appears to act similarly to colicins E1 and K.

Bacteriocins as a Promising Antimicrobial Strategy Against Multidrug‐Resistant Pathogens: Mechanisms of Action, Applications in Human and Animal Health, and the Food Industry

BioMed Research International, Volume 2026, Issue 1, 2026.
The global rise of antimicrobial resistance has significantly increased the difficulty treating infectious agents, creating an urgent need for alternative therapeutic strategies. In this context, bacteriocins have emerged as a promising solution, offering a potential alternative to conventional antibacterial therapies.

Bacteriocin synthesis in uropathogenic and commensal Escherichia coli: colicin E1 is a potential virulence factor

BMC Microbiology, 2010
Background Bacteriocin production is an important characteristic of E. coli strains of human origin. To date, 26 colicin and 9 microcin types have been analyzed on a molecular level allowing molecular detection of the corresponding genes.

An engineered bacterium auxotrophic for an unnatural amino acid: a novel biological containment system [PDF]

PeerJ, 2015
Biological containment is a genetic technique that programs dangerous organisms to grow only in the laboratory and to die in the natural environment. Auxotrophy for a substance not found in the natural environment is an ideal biological containment. Here,
