Doctors prescribe more antibiotics when expectations are high

17/02/2017

Experimental evidence confirms what surveys have long suggested: Physicians are more likely to prescribe antibiotics when they believe there is a high expectation of it from their patients, even if they think the probability of bacterial infection is low and antibiotics would not be effective, according to a study published by the American Psychological Association.

Faster way of detecting bacteria

08/02/2017

Brett Etchebarne, an assistant professor of emergency medicine in the College of Osteopathic Medicine at Michigan State University, has created a molecular diagnostic system that can identify dangerous bacteria such as E. coli, staph infections, and even some superbugs.

How multi-resistant pathogens can be defeated

07/02/2017

The steadily increasing resistance of many pathogens to antibiotics is one of the major challenges of modern medicine. Many of the common antibiotics have already lost their effect. Accordingly, there is an urgent need for alternatives to antibiotics for the treatment of infections that are caused by multi-resistant bacteria, one of which is anti-virulence therapy.

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.

Gram-negative bacteria pose a major challenge for hospitals

01/06/2016

Every day, people are admitted to the hospital, discharged or they visit patients. This large number of people increases the risk of bacteria transmission. Preventative measures such as short-sleeved uniforms and copper surfaces can help by improving hospital hygiene but they cannot replace the legal requirements for hygiene measures.

Plasmasterilization: active ingredient cocktail to fight bacteria

01/06/2016

Until now, plasma, the fourth state of matter,was consideredfascinatingonly to astrophysicists and science fiction fans. But at this point, it also attracts the interest of medicine because plasma can have many uses in this field. In the future, plasma sterilization could become an important component of hospital hygiene-provided that the right device is being used.

Fecal microbiota transplantation: A stranger’s stool heals inflammatory bowel disease

05/01/2015

It sounds strange: During fecal microbiota transplantation, the stool of a healthy donor is transferred into the intestines of a diseased patient to restore his or her damaged gut flora. This is an entirely normal process in the animal kingdom. Now the stool transplant has established itself as the standard for treating Clostridium difficile.
