Combined resistance to multiple antibiotics: A growing problem in the EU
(European Centre for Disease Prevention and Control (ECDC)) On the occasion of the 10th European Antibiotic Awareness Day, the European Centre for Disease Prevention and Control (ECDC) is releasing its latest EU-wide data on antibiotic resistance, as well as its guidance on prevention and control of carbapenem-resistant Enterobacteriaceae (CRE). In 2016, combined resistance to several antibiotic groups continued to increase for Escherichia coli and Acinetobacter species. This situation is of great concern as patients infected with these multidrug-resistant bacteria have very limited treatment options. (Source: EurekAlert! ...

Kitchen sponges may be a 'bacteria hotspot' – but no need to worry
Conclusion There's no need to panic about the results of this study. Bacteria are everywhere, so it's no surprise to find them growing in kitchens. The researchers say sponges, being porous and usually damp, represent ideal conditions for bacteria to grow. The study found that one of the most dominant types of bacteria came from the Moraxella family. These bacteria are often found on human skin, so it's likely they got onto the sponges from people's hands. Moraxella are also linked to the unpleasant smell sometimes found after laundry has taken longer to dry, so they seem to be common in the household environment.  T...

Sewage Saved This Man's Life. Someday It Could Save Yours.
When Thomas Patterson woke up from a two-month coma in March 2016, he learned two things he couldn’t believe: Donald Trump was soon to become the Republican nominee for president, and his wife, Steffanie Strathdee, had saved him from dying of an antibiotic-resistant superbug by injecting him with viruses harvested from sewage. It took a lot of convincing for him to accept these weren’t just more hallucinations. Patterson and Strathdee met while serving on a National Institutes of Health grant review panel almost 16 years ago. Strathdee doesn’t usually find review panels a riveting experience, but when she...

These 3 Superbugs Pose The Greatest Risk To Human Health
The World Health Organization is issuing a warning about a group of deadly bacteria: Recently, the WHO released its first-ever list of “priority pathogens,” a list of antibiotic-resistant bacteria that the organization says pose the greatest threat to human health. The list is divided into three categories: critical-, high- and medium-priority. Three pathogens made it into the critical-priority group. These bacteria are resistant to multiple antibiotics and pose a high risk to people in hospitals and nursing homes, the WHO says. Multidrug-resistant bacteria, sometimes called “superbugs,” are a ...

WHO Says New Drugs Urgently Needed To Fight 12 'Priority Pathogens'
New antibiotics need to be developed urgently to combat 12 families of bacteria, the World Health Organization said on Monday, describing these “priority pathogens” as the greatest threats to human health. The United National health agency said many of these bacteria have already evolved into deadly superbugs that are resistant to many antibiotics. The bugs “have built-in abilities to find new ways to resist treatment” the WHO said, and can also pass on genetic material that allows other bacteria to become drug-resistant. Governments need to invest in research and development (R&D)if new drugs a...

Polymyxin Susceptibility Testing: a Cold Case Reopened
In recent years, the emergence of multidrug-resistant Gram-negative rods and a dwindling antimicrobial armamentarium has led to renewed use of the polymyxins. With increasing use of polymyxins, there has been increase in resistance among previously susceptible populations of Pseudomonas aeruginosa, Klebsiella pneumoniae, and Acinetobacter baumannii. Unfortunately, susceptibility testing for the polymyxins is fraught with difficulties, making clinically informative interpretation of these tests challenging.

Wet wipes may help spread hospital bugs
Conclusion This research suggests detergent cleaning wipes used in UK hospitals and the home show large variability in their ability to kill three selected microbes, including Staphylococcus aureus and Clostridium difficile. Researchers tested seven commonly used wipes and found they varied a lot in their ability to kill the bugs. More worryingly, it looked like the wipes were picking up the germs rather than killing them – in almost all the wipes tested, the bugs were spread if they were used on a different surface. The implication of this is that wipes shouldn't be used on consecutive surfaces. The authors mention...

Detection of Carbapenemases Using Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF MS) Meropenem Hydrolysis Assay
Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) has been recently introduced to many diagnostic microbiological laboratories. Besides the identification of bacteria and fungi, that technique provides a potentially useful tool for the detection of antimicrobial resistance, especially of that conferred by β-lactamases. Here, we describe an assay allowing a detection of meropenem hydrolysis in clinical isolates of Enterobacteriaceae, Pseudomonas spp., and Acinetobacter baumannii using MALDI-TOF MS. This method is able to confirm carbapenemases within 3 h. The results are import...
