Aspects of Bacterial Resistance to Silver

  title={Aspects of Bacterial Resistance to Silver},
  author={Susanne S{\"u}tterlin},
Bacterial resistance to antibiotics has increased rapidly within recent years, and it has become a serious threat to public health. Infections caused by multi-drug resistant bacteria entail higher ... 

Presence of Silver Resistance Genes is not associated with Minimum Inhibitory Concentration of Silver Nanoparticles against Staphylococcus aureus and Escherichia coli

The frequency of the silver resistance genes among S. aureus and E. coli isolates is very low and there is no relationship between presence of the resistance genes and the MIC value of silver nanoparticles.

Properties, mechanism and applications of diamond as an antibacterial material

Abstract Antibiotic resistance in bacteria is a current threat causing an increasing number of infections of difficult clinical management. While the overuse and misuse of antibiotics are

Copper and Silver Biocidal Mechanisms, Resistance Strategies, and Efficacy for Legionella Control

A literature survey was conducted to assess current knowledge about the biocidal mechanisms of copper and silver ions against Legionella spp.

Genomic Analysis of Multidrug-Resistant Hypervirulent (Hypermucoviscous) Klebsiella pneumoniae Strain Lacking the Hypermucoviscous Regulators (rmpA/rmpA2)

This study documented the presence of a rare MDR hvKP with hypermucoviscous regulators and lacking the common capsule regulators, which needs more focus to highlight their epidemiological role.

Screening of silver resistance gene in clinical isolates and determination of Minimum Inhibitory Concentration (MIC) for silver nitrate

Functional Finishing of Barkcloth for Antimicrobial Properties Using Zinc Oxide Nanoparticles

Barkcloth a naturally occurring cellulosic non-woven fabric has recently obtained attention within the scientific community for end use applications in various industries for instance automobile,

Influence of titanium dioxide modification on the antibacterial properties

Abstract Antibacterial properties of 15 titania photocatalysts, mono- and dual-modified with nitrogen and carbon were examined. Amorphous TiO2, supplied by Azoty Group Chemical Factory Police S.A.,

Evaluation of central venous catheters coated with a noble metal alloy—A randomized clinical pilot study of coating durability, performance and tolerability

In this pilot study the BIP CVC had significantly lower AEs and showed a comparable performance to the standard CVC, and the coating was durable throughout the study length and toxicological evaluation showed good safety margins.

Long-term use of noble metal alloy coated urinary catheters reduces recurrent CAUTI and decreases proinflammatory markers

Long-term use of a NMA-coated catheter, coated with a noble metal alloy of gold, silver, and palladium, was associated with cessation of frequent CAUTIs and the catheter was experienced as comfortable and inflammatory markers were reduced with time.

Photocatalytic and antibacterial activities of silver and iron doped titania nanoparticles in solution and polyaspartic coatings

Ag doped nTiO2 samples delivered the best and excellent antibacterial action, even in the dark, attributed to both an enhanced band gap and surface area, as well as a combination of photocatalytic activity and Ag being present at the nanoparticle's surface.

The re-emergence of infection due to multidrug-resistant Gram-negative bacteria in critically ill patients presents particular challenges to clinicians, given the lack of a pipeline of new

Dissemination of Clonally Related Escherichia coli Strains Expressing Extended-Spectrum β-Lactamase CTX-M-15

E. coli ST131 and ST405 and multidrug-resistant IncFII plasmids may determine spread of this lactamase.

Mechanism of resistance to silver ions in Klebsiella pneumoniae

AgNO3 at a concentration of 40 micrograms/ml decreased the succinate dehydrogenase activity in susceptible and resistant strains by 100 and 18%, respectively, suggesting more than one resistance mechanism may be involved.

Development of Resistance during Antimicrobial Therapy Caused by Insertion Sequence Interruption of Porin Genes

ABSTRACT We have demonstrated by using an in vitro approach that interruption of the OmpK36 porin gene by insertion sequences (ISs) is a common type of mutation that causes loss of porin expression

Bacterial multidrug efflux transporters.

The current knowledge of individual pump components of the Cus system, a paradigm for efflux machinery, is described and speculation on how RND pumps assemble to fight diverse antimicrobials is speculated.

  • 2001
In summary, emerging resistance has required adaptations and modifications of laboratory diagnostic techniques, empiric anti-infective therapy for such diseases as bacterial meningitis, and infection control measures in health care facilities of all kinds.

Silver Enhances Antibiotic Activity Against Gram-Negative Bacteria

This work shows that silver can be used to enhance the action of existing antibiotics against Gram-negative bacteria, thus strengthening the antibiotic arsenal for fighting bacterial infections.

Plasmid-determined silver resistance in Pseudomonas stutzeri isolated from a silver mine

A silver-resistant strain of Pseudomonas stutzeri was isolated from a silver mine. It harbored three plasmids, the largest of which (pKK1; molecular weight, 49.4 X 10(6)) specified silver resistance.

Why are antibiotic resistance genes so resistant to elimination?

The euphoria produced by the discovery of antibiotics led to confident predictions that bacterial diseases would soon be conquered and could thus be safely forgotten, leaving scientists free to
