New type of monitoring: life of bacteria in microdroplets

12/01/2017

In the future, it will be possible to carry out tests of new drugs on bacteria much more efficiently using microfluidic devices, since each of the hundreds and thousands of droplets moving through the microchannels can act as separate incubators.

Antibiotic resistance just became more complex

05/01/2017

Bacteria that are susceptible to antibiotics can survive when enough resistant cells around them are expressing an antibiotic-deactivating factor. This new take on how the microbial context can compromise antibiotic therapy was published by a team of microbiologists from the University of Groningen microbiologists, together with colleagues from San Diego, in the journal "PLOS Biology".

"Pulling" bacteria out of blood

12/12/2016

Blood poisoning is still fatal in more than 50 percent of cases, but can be cured if treated at an early stage. The highest priority is therefore to act quickly. For this reason, doctors usually administer antibiotics even in the event of a suspicion of blood poisoning, without first ascertaining whether it is actually a bacterial sepsis.

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.
