Oxygen can wake up dormant bacteria for antibiotic attacks

09/12/2016

Bacterial resistance does not come just through adaptation to antibiotics, sometimes the bacteria simply go to sleep. An international team of researchers is looking at compounds that attack bacteria's ability to go dormant and have found the first oxygen-sensitive toxin antitoxin system.

Personalized antibiotic treatment

23/11/2016

A team of researchers from the University of Freiburg has developed a system inspired by biology that can detect several different antibiotics in human blood or other fluids at the same time. This biosensor system could be used for medical diagnostics in the future.

Airports: Dangerous germs travel as stowaways

22/11/2016

As scientists from Münster University, in collaboration with the Robert Koch Institute in Berlin, have now demonstrated, toilets at airports are also a "transfer point" for germs. These include germs against which traditional antibiotics for the treatment of bacterial infections are not, or only partially, effective.

Worrying traces of resistant bacteria in air

21/11/2016

Polluted city air has now been identified as a possible means of transmission for resistant bacteria. Researchers in Gothenburg have shown that air samples from Beijing contain DNA from genes that make bacteria resistant to the most powerful antibiotics we have.

Researchers discover new antibiotics by sifting through the human microbiome

17/11/2016

Most antibiotics in use today are based on natural molecules produced by bacteria--and given the rise of antibiotic resistance, there's an urgent need to find more of them. Researchers at The Rockefeller University have found a way around these problems, however.

World Antibiotic Awareness Week – Antibiotics: Handle with care

10/11/2016

Antimicrobial resistance (AMR) is a great danger and a threat – not only to an individual person, but also to modern healthcare. This year the World Health Organization (WHO) proclaims the World Antibiotic Awareness Week for the second time. With the topic "Antibiotics: Handle with care", the organization wants to call attention to the danger of AMR and to show what everybody can do against it.

Scientists model outer membrane of 12 bacterial species to speed new drugs for 'bad bugs'

19/10/2016

Led by Lehigh University professor, the team utilized biomolecular systems simulation to reveal the membrane properties of 21 distinct Lipid A types from 12 Gram-negative bacterial species--a crucial step toward new antibiotic drug development.

Children: antibiotic exposure associated with food allergy risk

21/09/2016

Antibiotic treatment within a child's first year of life may wipe out more than an unwanted infection: exposure to the drugs is associated with an increase in food allergy diagnosis, new research from the University of South Carolina suggests.
