Mechanisms of Silver Nanoparticle Action in Bacteria and Potential for Bacterial Resistance The antimicrobial activity of silver in general‚ and of silver nanoparticles in particular‚ is of significant interest because it appears to be independent of the strain of bacteria. Crucially‚ antibiotic resistant strains‚ MRSA (methicillin‚ or multiple-resistant Staphylococcus aureus)‚ E. coli O157‚ and others are affected by silver [6]. The reasons for this are not fully clear as yet‚ but could be related

The Antimicrobial Properties of Plants [Garlic and Mint] AIM: to investigate the antimicrobial properties of garlic and mint and how effective they were. We were trying to see whether the bacteria will grow around the different plants. VARIABLES: Independent: type of plant used Dependent: the diameter in mm of clearing Confounding: room temperature‚ surrounding bacteria‚ concentration of plant solution HYPOTHESIS My hypothesis is that garlic will be least affected by the bacteria as it will

resistance. The most promising candidates to be developed as alternative drugs are the antimicrobial peptides. In the present study the antimicrobial peptide Microcin C7 was docked with the catalytic domain of Diphtheria toxin and further the simulational studies were performed to find the stability of the complex. The results were significant and hence it was predicted that further work can be done on antimicrobial peptide to develop it as an altenative drug against Diphtheria toxin. Keywords- I. INTRODUCTION

Chem 253 Lab 1: Acid/Base Properties of an Antimicrobial Agent 09/03/13 Purpose The purpose was to determine the acid and base properties of the antimicrobial agent sodium benzoate. Theory Sodium has mainly been used in food processing to avoid growth of bacteria and harmful microorganisms. It is commonly used to preserve foods and beverages that have an acidic pH. Rather than benzoic acid‚ sodium benzoate is used because it is generally soluble in most aqueous solutions but benzoic

In the story “Pancakes‚” the author‚ Joan Bauer‚ creates an irritated tone. Irritated is defined as showing or feeling slight anger or annoyance. First of all‚ in the exposition of the story‚ the protagonist wakes up and finds an article about being a perfectionist on her mirror. Instantly she was annoyed because a month before her boyfriend had accused her of being a perfectionist (194). By including this‚ the author is able to convey that Jill had repeatedly been accused in some way of being a

Chapter One INTRODUCTION Herbal medicines tend to look primitive and unscientific when compared to synthetic (conventional) drugs‚ which are thought to be more reliable than those made from plants. Herbal medicine is still the mainstay of about 75-80% of the world population‚ mainly in the developing countries for primary health care (Kamboj‚ 2000). This is primarily because of the general belief that herbal drugs are without any side effects‚ besides being cheap and locally available. The

soils isolated from geographically separate areas of Jordan‚ Micrococcus luteus and Staphylococcus aureus were rapidly killed. Over the 3-week incubation period‚ the number of specific types of antibiotic-producing bacteria increased‚ and high antimicrobial activity (MIC‚ ∼10 μg/ml) was observed in methanol extracts of the inoculated red soils. Antibiotic-producing microorganisms whose numbers increased during incubation included actinomycetes‚ Lysobacter spp.‚ and Bacillus spp. The actinomycetes
