A newly discovered bacterial family may become a weapon in the fight against malaria

A new family of bacteria that are common in malaria mosquitoes has been described by researchers at Swedish University of Agricultural Sciences (SLU) and Uppsala University in Sweden, Justus-Liebig-Universität Giessen, Germany, and the Veterinärmedizinische Universität, Austria. Now, attempts ar... Read More

First results from Ebola vaccine trial show acceptable safety profile

The first results from a trial of a candidate Ebola vaccine at Oxford University suggest the vaccine has an acceptable safety profile at the doses tested, and is able to generate an immune response.

'The vaccine was well tolerated. Its safety profile is pretty much as we had hoped,' said Prof... Read More

Superbug outbreak has killed two at UCLA medical center

This week, doctors at the University of California Los Angeles Medical Center discovered that a contaminated medical tool had been spreading antibiotic-resistant bacteria to patients.

Bacteria's hidden traffic control

Not unlike an urban restaurant, the success of a bacterial cell depends on three things: localization, localization and localization. But the complete set of controls by which bacteria control the movement of proteins and other essential biological materials globally within the confines of their... Read More

Could Proteins from Frog Skin Be Source of New Class of Antibiotics?

With minor tinkering, a peptide—a tiny protein—from the skin of a frog could be fashioned into a novel antibiotic that would lack the toxic byproducts of some more conventional drugs. More importantly, such peptides would represent a new class of antibiotics, at a time when new classes are so... Read More

World Health Organization approves 15-minute Ebola detection test

Until now, the standard way to check for Ebola in the region was to use the nucleic acid test, which works by identifying the genetic materials of the virus from a blood sample. Yet the test requires a full lab to succeed, and it takes between 12 to 24 hours to process the results. In comparison... Read More

Key to blocking influenza virus may lie in a cell’s own machinery

Viruses are masters of outsourcing, entrusting their fundamental function – reproduction – to the host cells they infect. But it turns out this highly economical approach also creates vulnerability.

Researchers at Rockefeller University and their collaborators have found an unexpected way the... Read More

Airport screening misses half of disease cases but could be improved

Scientists have shown that airport screening for disease will often miss half or more of infected travelers, but can be improved by customizing to pathogens. The findings are published in the journal eLife.

They present options for policy makers; for example whether resources would be better ... Read More

Canned fruit safer than the frozen variety

Canned fruit is often safer than the frozen variety according to University of NSW Associate Professor Julian Cox, an expert in food microbiology.

"The heat treatment used to make canned products shelf stable in ambient temperatures is much more than sufficient to kill micro-organisms includi... Read More

Breastfeeding, Other Factors Help Shape Immune System Early in Life

Henry Ford Hospital researchers say that breastfeeding and other factors influence a baby’s immune system development and susceptibility to allergies and asthma by what’s in their gut.

The striking findings from a series of studies further advance the so-called hygiene hypothesis theory that ... Read More

Bacterial Armor Holds Clues for Self-Assembling Nanostructures

Imagine thousands of copies of a single protein organizing into a coat of chainmail armor that protects the wearer from harsh and ever-changing environmental conditions. That is the case for many microorganisms. In a new study, researchers with the U.S. Department of Energy (DOE)’s Lawrence Berk... Read More

More infectious diseases emerging because of climate change

The appearance of infectious diseases in new places and new hosts, such as West Nile virus and Ebola, is a predictable result of climate change, says a noted zoologist affiliated with the Harold W. Manter Laboratory of Parasitology at the University of Nebraska-Lincoln.

In an article publishe... Read More

Infectious agents with no genome

If the reader does not believe that viroids and satellites are distinctive, then surely prions, infectious agents composed only of protein, must impress.

The question of whether infectious agents exist without genomes arose with the discovery and characterization of infectious agents associat... Read More

Global Fund Needed to Fight Dangerous Superbugs
