Mechanism of antibacterial activity of copper nanoparticles

Nanotechnology, 2014
In a previous communication, we reported a new method of synthesis of stable metallic copper nanoparticles (Cu-NPs), which had high potency for bacterial cell filamentation and cell killing. The present study deals with the mechanism of filament formation and antibacterial roles of Cu-NPs in E. coli cells.

Mechanisms of antibacterial immunity of mucous membranes

Folia Microbiologica, 1984
A survey based on both literary data and the authors own results, concerning the mechanisms of sIgA-mediated antibacterial immunity, is presented. Secretory IgA is characterized as a specific component of the immune system of mucous membranes, which can recognize harmful bacterial and distinguish them from indigenous microflora physiologically ...

Mechanism of the antibacterial action of spermine

Archives of Biochemistry and Biophysics, 1959
Abstract 1. 1. Spermine was adsorbed by various bacterial cells, following an adsorption isotherm. No correlation was observed between the quantity of spermine adsorbed by the bacteria and their sensitivity to the drug. The adsorption of spermine decreased in the presence of high concentrations of hydrogen ions or other cations. 2. 2. Various

Antibacterial mechanisms of graphene-based composite nanomaterials

Nanoscale, 2017
Pathogenic bacteria are gaining resistance to conventional antibiotics at an alarming rate due to overuse and rapid transfer of resistance genes between bacterial populations. As bacterial resistance to antibiotics causes millions of fatalities worldwide, it is of urgent importance to develop a new class of antibiotic materials with both broad-spectrum

Lasso-inspired peptides with distinct antibacterial mechanisms

Amino Acids, 2014
Microcin J25 (MccJ25) is an antibacterial peptide with a peculiar molecular structure consisting of 21 amino acids and a unique lasso topology that makes it highly stable. We synthesized various MccJ25-derived peptides that retained some of the inhibitory activity of the native molecule against Salmonella enterica and Escherichia coli.

Antibacterial Effects of Chitosan Powder: Mechanisms of Action

Environmental Technology, 2007
Chitosan, the deacetylated derivative of chitin, is a natural D-glucosamine polymer that can be extracted from the shells of seafood such as prawns crabs and lobsters. It can be used as a flocculent, plant disease resistant promoter, anti-cancer agent, wound healing promotion agent and antimicrobial agent.

Mechanism of antibacterial phytoconstituents: an updated review

Archives of Microbiology
The increase of multiple drug resistance bacteria significantly diminishes the effectiveness of antibiotic armory and subsequently exaggerates the level of therapeutic failure. Phytoconstituents are exceptional substitutes for resistance-modifying vehicles. The plants appear to be a deep well for the discovery of novel antibacterial compounds.

Understanding the antibacterial mechanism of metal surfaces

Acta Biomaterialia
Bacterial inactivation on antibacterial metal surfaces has been widely used in medicine and daily life to inhibit infection caused by surface contact. However, the underlying antibacterial mechanism of metal surfaces has remained elusive due to a lack of comprehensive theoretical perspectives and direct evidence.

Mechanisms of Antibacterial Drug Resistance

Antibacterial resistance is an escalating worldwide public health challenge with substantial ramifications for global well-being. It has emerged as a critical global health concern. As defined by the World Health Organization (WHO), antimicrobial resistance (AMR) denotes the capacity of microorganisms to endure antimicrobial therapies.
