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.

New class of bacteria busting antimicrobials

A new type of spiral polypeptides, produced at the University of Illinois, may signal a new type of antimicrobial. The polypeptides target the outer membrane of the bacterial cell wall.

Two-thirds of antibiotics are needlessly prescribed

London - A new report, aimed at the U.K. but applicable to most parts of the developed world, has concluded that around two-thirds of antibiotics are unnecessarily prescribed and are of no effect.

Call for rapid tests to stem antibiotic overuse

A report has called for a new wave of testing to be introduced to allow doctors to assess whether a patient needs antibiotics. The idea is to reduce situations where a patient is given antibiotics based on an absence of medical evidence.

U.K. seeking antibiotic guardians

London - The British government is seeking healthcare professionals and members of the public to become "antibiotic guardians." This is to help with using antibiotics more wisely and helping to conserve stocks.

Wastewater may not trigger antibiotic resistance

Copenhagen - Some scientists have been concerned that wastewater, where bacteria and antibiotics mix, could be seeding an increase in antibiotic resistance. A new study puts forward evidence that this is not the case.

Time to clamp down on 'soft touch' doctors?

London - Should doctors who indiscriminately administer antibiotics to appease patients where there is no clinical need to do so be fined? This is the call of a leading health expert.

European Union takes action on antibiotics

One root of antibiotic resistance is from animals to people. To assess this, the European Medicines Agency (EMA) is running a public consultation on how to assess the risks of antimicrobial resistance passing from food animals to human.

Garlic helps treat urinary tract infections

Extracts of garlic could help to combat types of multi-drug resistant bacterial pathogens that can cause urinary tract infections (UTI), according to new research.

Is pharmaceutical waste triggering antibiotic resistance?

Several pharmaceutical companies have been accused by a campaign organization of contributing to the rise of antibiotic resistance among types of pathogenic bacteria, the so-termed "super bugs."

Call for fund to develop new antibiotics

A British economist is calling on the world's leading pharmaceutical companies to set up a $2 billion fund to enable research into new antibiotics.

Thousands sign up to Antibiotic Guardians

London - Across the U.K., over 8,100 healthcare professionals and some 3,600 members of the public have pledged to do their own part to help reduce antibiotic resistance by becoming “antibiotic guardians.”

Get Smart About Antibiotics Week Special

This week is “Get Smart About Antibiotics Week.” This is an international collaboration between U.S., Europe, Australia and Canada.

Computer design helps build new antibiotics

Technologists and biologists have combined resources to use computer simulations to show how bacteria are able to destroy antibiotics. This combination approach could lead to the development of a new generation of drugs.
