Running out of treatments: The problem superbugs resistant to everything

02.04.2008
Doctors are running out of treatments for today’s trauma victims and critically ill patients because of infections due to drug resistant microbes – even after resorting to using medicines thrown out 20 years ago because of severe side effects, scientists heard today (Tuesday 1 April 2008) at the Society for General Microbiology’s 162nd meeting being held this week at the Edinburgh International Conference Centre.

“Doctors in many countries have gone back to using old antibiotics that were abandoned 20 years ago because their toxic side effects were so frequent and so bad”, says Professor Matthew Falagas from the Alfa Institute of Biomedical Sciences in Athens, Greece and Tufts University School of Medicine, Boston, Massachusetts. “But superbugs like Acinetobacter have challenged doctors all over the world by now becoming resistant to these older and considered more dangerous medicines”.

“Even colistin, a polymyxin type antibiotic discovered 60 years ago, has recently been used as a salvage remedy to treat patients with Acinetobacter infections”, says Professor Falagas. “And it was successful for a while, but now it occasionally fails due to recent extensive use that has caused the bacteria to become resistant, leading to problem superbugs which are pan-drug resistant, in other words resistant to all available antibiotics”.

The Greek researchers have also shown in new data analyses that Acinetobacter is a more serious threat than previously thought – it doesn’t just cause severe infections, it kills many more patients than doctors had realised. Acinetobacter can cause pneumonia, skin and wound infections and in some cases meningitis.

The scientists have also identified a whole range of drug resistant strategies being used by the bacteria, including the production of compounds which can inactivate the drug treatments, cell pumps that can bail out the drug molecules from inside bacterial cells making them ineffective, and mutating the drug target sites making the drug molecules miss or fail to latch onto the specific regions of the bacterial cells that they were aiming for.

“There have already been severe problems with critically ill patients due to Acinetobacter baumannii infections in various countries”, says Matthew Falagas. “In some cases we have simply run out of treatments and we could be facing a pandemic with important public health implications”.

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

Im Focus: Entangled atoms shine in unison

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...

Im Focus: Computer-Designed Customized Regenerative Heart Valves

Cardiovascular tissue engineering aims to treat heart disease with prostheses that grow and regenerate. Now, researchers from the University of Zurich, the Technical University Eindhoven and the Charité Berlin have successfully implanted regenerative heart valves, designed with the aid of computer simulations, into sheep for the first time.

Producing living tissue or organs based on human cells is one of the main research fields in regenerative medicine. Tissue engineering, which involves growing...
