Stable Fluorinated Antimicrobial Coatings
Contact antimicrobials for use in the medical device industry are being studied extensively to minimize the risk of hospital acquired infections, which are among the top ten leading causes of death in the US. Surfaces modified with quaternary ammonium containing side chains have been known to …

Novel Endogenous Antimicrobial Peptides
Antimicrobial peptides serve as a first line of defence against invading microorganisms and are an essential part of our fast innate immune system. They are ancient molecules found in all classes of life. Antimicrobial peptides rapidly kill a broad spectrum of microbes and are immunomodulatory, …

Nanostructured Coatings for Antimicrobial Applications
… developed and assessed with respect to their antimicrobial activity. A quartz crystal microbalance was used to monitor the built up of the multilayers in real time, confirming the presence of strong electrostatic interactions between the negatively charged Nafion and the positively charged …

Cyclodextrin complexes of antimicrobial agents
… hydroxypropyl--CyD (HP--CyD, M.S. = 0.6) with antimicrobial agents of limited solubility in an attempt to increase their microbiological efficacy. The agents studied were chlorhexidine dihydrochloride (CHX), p-hydroxybenzoic acid esters (methyl, ethyl, proply and butyl) and triclosan. The …

ANTIMICROBIAL PEPTIDES FOR A SUSTAINABLE AGRICULTURE
L'agricoltura moderna si basa principalmente sull'utilizzo di pesticidi chimici per proteggere le colture da patogeni e parassiti. Tuttavia, l'uso massiccio di questi composti ha portato all'insorgenza di ceppi resistenti, all'inquinamento ambientale e al danno agli organismi non bersaglio. Per …

DEVELOPMENT OF NOVEL COPOLYOXETANES: ANTIMICROBIAL AGENTS
<p>This thesis focuses on solution antimicrobial effectiveness for copolyoxetanes with quaternary ammonium and PEG-like side chains. Ring opening copolymerization of 3-((4-bromobutoxy)methyl)-3-methyloxetane (BBOx) and 3-((2-(2-methoxyethoxy) ethoxy) methyl)-3-methyloxetane (ME2Ox) yielded random …

Geographical Incidence of Antimicrobial Resistant Gonorrhea
… of gonococcal isolate resistance to current antimicrobials began in the 80’s and has continued since, collecting isolates from 25 sites nationwide. These isolates assist researchers in finding susceptibility levels and resistance rates as they emerge. Over time, however, resistance began …

Resistance to antimicrobial agents in bifidobacteria
… risks of acquisition of genes for resistance to antimicrobial agents. Although bifidobacteria exhibit resistance to a wide range of antibiotics, little is known about the molecular basis for this resistance. The aim of this project was, therefore, to investigate the molecular mechanisms …

Pinnipeds as sentinels of antimicrobial resistance: mapping antimicrobial resistance genes in the waters of the United Kingdom
Antimicrobial resistance (AMR) is a continual and growing threat to human and animal health. There is a lack of information about environmental reservoirs of AMR, many of which feed into the marine habitat. Pinnipeds are often used as sentinels of ocean health because they are long lived, apex …

Optimization of antimicrobial chitosan coating for silicone
… The current project focused on developing antimicrobial coatings, based on chitosan, for silicone elastomers, a common material in implants and other medical devices. Chitosan is a natural amino polysaccharide that is both antimicrobial and biocompatible.

Modes of action of antimicrobial garlic derivatives
… (G. P) have been studied with respect to their antimicrobial modes of action with reference to gut environments. Results obtained in this thesis indicate: - 1) A method of preparing G. P for use was developed and the allicin content (from alliin) determined by both pyruvate and ammonia assays to …

Lysin Based Antimicrobial Peptides Against Acinetobacter Baumannii
<p>Acinetobacter baumannii is a Gram-negative bacterial pathogen responsible for a range of nosocomial infections. The recent rise and spread of multidrug resistant A. baumannii clones has fueled a search for alternative therapies, including bacteriophage endolysins with potent antibacterial …

Mining Marine Environments for Novel Antimicrobial Biologics
Deaths attributable to antimicrobial resistance (AMR) are predicted to rise from 700,000 per year now to 10 million by 2050. There is an urgent need for new antibiotics to meet the threat posed by AMR; the WHO recently reported that there are not enough antibiotics in development to meet this need. …
