Path to deadly sepsis varies by bacterial infection
Sepsis remains a common and deadly condition that occurs when the body reacts to an infection in the bloodstream. Scientists know little about the early stages of the condition; however, physicians must act fast. Every hour that passes without one or more of the few treatments available increases the risk of death.

The microbiota in the intestines fuels tumour growth
Cell stress in combination with an altered microbiota in the colon drives tumour growth. Previously, it was assumed that this combination only contributes to inflammatory intestinal diseases.

New accelerated diagnosis of multi-resistant hospital pathogens
A team of researchers at the University of Cologne's Faculty of Medicine and the German Center for Infection Research (DZIF) use a novel immunochromatographic method to detect bacteria that are resistant to the antibiotic group carbapenemes within 20 to 45 minutes from blood cultures with 100 percent certainty.

Will resistant bacteria be the end of alcohol hand sanitizers?
Alcohol-based hand sanitisers have been a mainstay in hospital hygiene for decades. But now, strains of antibiotic-resistant bacteria show signs of overcoming these handwashing agents as well. Does this mean we should just stop sanitising our hands? Not so fast, say researchers from Melbourne – however, hospitals now need to re-think their strategies to protect their patients from deadly…

Biomarker is discovered for a flesh-eating pathogen
Imagine a pathogen that infects completely healthy people and can cause blindness in one day and flesh-eating infections, brain abscesses and death in just a few days. Now imagine that this pathogen is also resistant to all antibiotics.

Two gene mutations transform harmless bacteria into dangerous strains
Since 2013, a new strain of meningococcal bacteria has spread rapidly in Niger and Nigeria, leading to large-scale outbreaks of meningitis. Analysis of the genetic material shows that with just two gene mutations, harmless bacteria transform into a strain that could cause major epidemics in these two countries.

"Universal antibodies" disarm various pathogens
Scientists from the German Cancer Research Center (DKFZ) have been studying how the immune system succeeds in keeping pathogens in check. For the first time, the researchers have now discovered antibodies that are capable of disarming not only one specific bacterium but a whole variety of microorganisms at once. The newly discovered antibodies recognize a tiny sugar structure found on the surface…

Promising vaccines against anthrax, plague and tularemia
Anthrax, plague and tularemia are three potent agents terrorists would be likely to use in an attack, according to the Centers for Disease Control and Prevention. Each is highly and quickly lethal to humans. But there are no licensed vaccines for tularemia and plague, and although there is an anthrax vaccine, it requires a burdensome immunization schedule and has severe side effects. Now, a…

MAIT cells sense metabolic state of enteric bacteria
A little-explored group of immune cells plays an important role in the regulation of intestinal bacteria. Changing metabolic states of the microbes have an effect on defense cells at different stages of alert or rest, as researchers from the Department of Biomedicine at the University and University Hospital of Basel report in the journal "Mucosal Immunology." It is known that the…

Little-known bacteria might grind Zika and dengue infections to a halt
A Vanderbilt team took the next leap forward in using a little-known bacteria to stop the spread of deadly mosquito-borne viruses such as Zika and dengue. Wolbachia are bacteria that occur widely in insects and, once they do, inhibit certain pathogenic viruses the insects carry. The problem with using Wolbachia broadly to protect humans is that the bacteria do not normally occur in mosquitoes…

Support from the other end of the world
Partners who could hardly be further apart – yet have a lot in common – have united to fight resistant pathogens. The International Consortium for Anti-Infective Research (iCAIR) is based in Germany and Australia – separated by nearly 16,000 km as the crow flies. This has not stopped the research cooperation from achieving its objectives: the development of new agents against infections.

How bacteria recover from antibiotics exposure
Beta-lactam antibiotics, including penicillin, are one of the most widely used classes of antibiotics in the world. Though they’ve been in use since the 1940s, scientists still don’t fully understand what happens when this class of drugs encounters bacteria. Now, researchers at the University of Notre Dame have elucidated how an enzyme helps bacteria rebound from damage inflicted by…

A new class of antibiotics to combat drug resistance
Researchers from the University of Illinois at Chicago and Nosopharm, a biotechnology company based in Lyon, France, are part of an international team reporting on the discovery of a new class of antibiotics. The antibiotic, first identified by Nosopharm, is unique and promising on two fronts: its unconventional source and its distinct way of killing bacteria, both of which suggest the compound…

Helicobacter creates immune system blind spot
While gastritis and gastric ulcer disease used to be put down to stress and dietary factors, it was discovered in the 1980s that the actual culprit is infection with a bacterium, H. pylori. This pathogen is now classed as a type I carcinogen by the WHO, as it is the major risk factor for development of gastric carcinoma. Attempts to develop a vaccine against H. pylori have been unsuccessful and…

WHO’s first release of surveillance data on antibiotic resistance reveals high levels of resistance to a number of serious bacterial infections in both high- and low-income countries. WHO’s new Global Antimicrobial Surveillance System (GLASS) reveals widespread occurrence of antibiotic resistance among 500 000 people with suspected bacterial infections across 22 countries.

Tracing the evolution of E. coli
Bacteria are stealthy organisms. They can multiply in minutes and evolve to survive what we throw at them—including antibiotics. The World Health Organization calls antibiotic resistance “one of the biggest threats to global health, food security, and development today.” Each year, about 2 million people in the United States become infected with antibiotic-resistant bacteria, according to…

After joint replacement: Novel method of isolating infecting organisms
Joint replacement surgery carries the risk of developing an infection in the replaced joint, which can lead to a so-called revision or re-do of the joint replacement. However, current diagnostic practices can fail to detect bacteria in 30-50 percent of clinical cases, complicating or delaying appropriate treatment. Thomas Jefferson University researchers have found that genomic analysis using…

Bacteria acquire resistance from competitors
Bacteria not only develop resistance to antibiotics, they also can pick it up from their rivals.
