Q&A: Genetic testing can identify antibiotic resistance Special

LexaGene has developed a point of care medical device that can identify pathogens as well as antibiotic/antimicrobial resistance within one hour. The device does this completely automatically through the amplification of genetic material.

Exploring CBD’s newly found antibacterial properties

Cannabidiol (CBD) may have a new property to add to the others that fall within the medicinal bracket: effectiveness against Gram-positive bacteria, including the ability to act upon some species classed as pathogenic.

Application of blue light to eliminate bacterial biofilms

An emerging, novel approach to control antibiotic-resistant bacterial infections is based on the use of light, in particular of blue wavelengths (400–470 nm). A new research paper of interest, concerning biofilm elimination by inducing oxidative stres

Rates of antimicrobial resistance rising drastically in animals

New research shows that antimicrobial-resistant infections are increasing in animals across low and middle income countries at a rate far faster that earlier predictions suggested.

Cannabis leaves show antibacterial effect against MRSA

The search for antimicrobials often leads scientists into the unlikeliest of areas. New research shows that the leaves of the cannabis plant have an antimicrobial effect, including efficacy against drug resistant forms of Staphylococcus aureus.

WHO outlines antimicrobial strategy (update)

At an audio briefing held on June 18, 2019, the World Health Organization (WHO) announced key goals to prevent antimicrobial resistance in countries around the world using a new tool, named AWaRe.

Endolysin technology looks set to replace antibiotics

The biotechnology company Micreos has raised €30 Million in funding for endolysin technology, a medical technology that could be set to replace antibiotics and overcome some of the challenges of antimicrobial resistance.

Essential Science: Genetic test for antimicrobial resistance

Scientists have put together a sensitive method to determine if bacteria carry a gene that can cause resistance to two common antibiotics. The test is rapid, and has been tested against ‘strep throat’ and other respiratory illnesses.

Fluorescent silk kills harmful bacteria

A far-red fluorescent silk can kill harmful bacteria, as demonstrated in controlled trials. The developers see the material as both a biomedical and and an environmental remedy to combating harmful organisms and protecting patients.

Diagnostic connectivity to combat antimicrobial resistance

London - The British government has entered into a partnership with FIND, a global non-profit dedicated to accelerating the development of diagnostic tests for diseases. This is to introduce digital technologies to combat the antimicrobial resistance problem.

New class of antibiotics to combat drug resistance

Chicago - A new class of antibiotic has been discovered. The chemical kills bacteria by binding to ribosome. This disrupts protein synthesis, and stops the microbial cell from replicating. This is a step forward in the search for new antimicrobials.

New class of antibiotics discovered in dirt

U.S scientists have discovered a new antibiotic family discovered from dirt (samples of soil). The discovery could represent a step forwards in the quest to find new types of antibiotics and antimicrobials.

Pfizer helps Indian government with antimicrobial resistance

New Delhi - The major drugs company Pfizer is working closely with the Indian Council of Medical Research (ICMR) to help combat antimicrobial resistance in India. This includes establishing a center in New Delhi to develop research.

Interview: The path to next-generation antibiotics Special

Dr. Marcos Pires is spearheading a novel approach to understanding bacterial cell wall changes in response to antibiotics that could be key to new drug design. We spoke with him to discover more about this approach.

Essential Science: New antibiotics from a molecular ‘sharpener’

Scientists have developed a "molecular pencil sharpener." This is a device that uses chemicals to generate a "warhead" of proteins that increase in toxicity once “sharpened”. The research has focused on killing the E. coli bacterium.

Therapy alternative to farm animal antibiotics

London - Despite longstanding scientific concerns, antibiotics continue to be given to farm animals as a means of producing leaner meat. This helps to spread antibiotic resistance. A new type of therapy offers an alternative.

Unnecessary antibiotics still prescribed for colds

Toronto - There has been plenty of publicity about prescribing antibiotics for viral infections, yet the problem continues within the medical community, according to a study of U.S. health sector practices. The problem connects with the antibiotic resistance issue.

Phage therapy aids man with multidrug-resistant infection

A novel application of bacteriophage therapy has saved the life of a man who contracted a multi-drug resistant bacterial infection. Phage therapy offers a promising new take on the fight against antibacterial resistance.

Harnessing silver for the antimicrobial fight

The use of silver to fight infections has been in place for thousands of years. Silver can still play a major role in the antibiotic fight. Researchers are using modern gene editing techniques to see how silver poisons pathogens.

Many household dogs are carrying MRSA

Community transferred and acquired MRSA is a growing concern, especially for those admitted to hospital. One common reservoir for the antibiotic-resistant bacteria are domestic dogs. A new study reveals the extent of the problem.

Antimicrobial resistant bacteria detected in air pollution

Areas subject to air pollution contain a growing concentration of bacteria that are resistant to antimicrobials, according to a new study. Consequently, air movement may provide a new ways for their transmission.

Antimicrobial resistance occurs naturally in soil bacteria

Bacteria, isolated from soil and with no known contact with human society, have been shown to exhibit antimicrobial properties. The organisms were isolated from in prairie soils.

Medics call for nine antibiotics per year limit

A new research paper has called on medics to restrict doses of antibiotics prescribed each year to nine per year. This is seen as necessary in order to limit antibiotic resistant bacteria.

Will reducing antibiotic use lead to more infections?

London - A consensus is developing around restricting the use of antibiotics and antimicrobials. However, what is the impact on human health if the use of these pharmaceutical compounds is curtailed?

Essential Science: How natural products can help fight pathogens

Although synthetic medicines provide the basis for most modern antimicrobials, have all natural remedies been exhausted? A new research paper suggests there are still some herbs still to be exploited.

Reduce antibiotic use now, say European parliamentarians

New measures are required to stem the use of antibiotics and antimicrobials in order to slow down the emergence of new ‘superbugs’ (multi-drug resistant bacteria.) To achieve this, European politicians call for new measures.

Big Pharma wants governments to pay for new antibiotics

Human society needs a new generation of antimicrobials to overcome the problem of multi-drug resistance. A key question stemming from this is who should pick up the bill?

Essential Science: Health effects of antibiotic use

A disturbing, newly issued report suggests just one single course of antibiotics can disrupt the microbial composition in the gut sufficiently to trigger a spate of unintended ill-health effects. Digital Journal gets to the bottom of the issue.

Do antibiotics to treat MRSA make patients sicker?

New evidence suggests certain antibiotics intended to treat patients with MRSA infections are actually causing more harm than good.

University receives funding to tackle antimicrobial resistance

Loughborough - Loughborough University has received $750,000 of funding to explore the issue of bacterial resistance to antibiotics and to look for new candidate compounds to use as antimicrobials.
