Researchers at Swansea University say a fungus could be the key to controlling mosquitoes.
Fungus Metarhizium anisopliae lives in soil and kills a whole range of insects and researchers say it also affects mosquito larvae if added to the water where the insect breeds.
The insects carry dis... Read More
Researchers have identified components in Clostridium difficile (C. diff) that may lead to new diagnostic tools, and ultimately more timely and effective treatment for this often fatal infection. C. diff is a spore-forming bacterium that causes severe diarrhea and is responsible for 14,000 death... Read More
A research team led by a molecular plant pathologist at the University of California, Riverside has discovered the mechanism by which an aggressive fungal pathogen infects almost all fruits and vegetables.
The team discovered a novel “virulence mechanism” — the mechanism by which infection ta... Read More
Small shifts in agricultural practices can increase or reduce the risk of salmonella and listeria contamination on produce, new research shows.
For example, applying manure within a year of harvesting produce boosts the odds of contaminating a field with salmonella, which is the biggest singl... Read More
The protein LIMP-2 is vital for both humans and animals. If it is absent – due, for example, to a hereditary disease – substances of an unknown nature, probably lipids, accumulate in the organism. Up to now, scientists were unsure what the protein looks like and how exactly it functions. Privatd... Read More
Scientists are testing vaginal pessaries containing 'good' probiotic bacteria for the treatment of vaginal thrush. The research shows that this approach is likely to be a viable alternative to using precious antimicrobial drugs.

A protein in Salmonella inactivates mast cells -- critical players in the body's fight against bacteria and other pathogens -- rendering them unable to protect against bacterial spread in the body, according to researchers at Duke Medicine and Duke-National University of Singapore (Duke-NUS).

When attacking body cells, bacteria, such as salmonellae or Yersinia (plague pathogens), inject specific bacterial proteins through hollow, syringe-like structures – called injectisomes – into the host cells. These substances reprogram the cells and can thus overcome their defense. From then on,... Read More
Ankyrin (ANK) repeats are one of the most common amino acid sequence motifs that mediate interactions between proteins of myriad sizes, shapes and functions. We assess their widespread abundance in Bacteria and Archaea for the first time and demonstrate in Bacteria that lifestyle, rather than ph... Read More
Escherichia coli – a friendly and ubiquitous bacterial resident in the guts of humans and other animals – may occasionally colonize regions outside the intestines. There, it can have serious consequences for health, some of them lethal.
In a new study conducted in assistant professor Melha M... Read More
But microbes are only part of the story — the effect also depends on a healthy diet. Gut bacteria from lean mice can invade the guts of obesity-prone cage-mates and help their new hosts to fight weight gain.
Researchers led by Jeffrey Gordon, a biologist at Washington University in St. Louis... Read More
Norman R. Pace, a microbiologist at the University of Colorado Boulder, pioneered the use of DNA to study microbes. He has searched for extremophiles (organisms that can exist in extreme environments) in the hot springs of Yellowstone National Park and once descended in the submersible Alvin to ... Read More
Endangered Amur tigers (also called Siberian tigers) face challenges from poaching, decimation of their prey base, and habitat fragmentation, but a disease from domestic dogs may be the straw that broke the tiger's back, according to the authors of a study in mBio this week. A team of scientists... Read More
On 3 April 2013, the China Health and Family Planning Commission notified WHO of an additional four cases of human infection with influenza A(H7N9). The four patients are from Jiangsu province in eastern China. There is no link between the cases.
The patients include a 45-year-old woman with ... Read More
Scientists have discovered a “microbial Pompeii” preserved on the teeth of skeletons around 1,000 years old.
The key to the discovery is the dental calculus, or “plaque,” which preserves bacteria and microscopic particles of food on the surfaces of teeth, effectively creating a mineral tomb f... Read More
When astronauts launch into space, a microbial entourage follows. And the sheer number of these followers would give celebrities on Twitter a run for their money. The estimate is that normal, healthy adults have ten times as many microbial cells as human cells within their bodies; countless more... Read More
Immune system defenses against dangerous bacteria in the gut can be breached by turning off a single molecular switch that governs production of the protective mucus lining our intestinal walls, according to a study led by researchers at Yale, the University of British Columbia, and the Weizmann...

Doses of a human gut microbe helped to reverse behavioral problems in mice with autism-like symptoms, researchers report today in Cell. The treatment also reduced gastrointestinal problems in the animals that were similar to those that often accompany autism in humans.
The work builds on prev... Read More
Depending upon whom you ask, the smell that has plagued La Jolla Cove has been “putrid,” “noxious” or “like the East River used to smell,” for quite a while. Nose-pinching is commonplace.
But now, the stench of bird guano emanating from the cliffs in the seaside neighborhood has become, off... Read More
In their paper in mBio this week, Wang et al present FrameBot, a program that combines frameshift correction and nearest-neighbor identification in one Java-based tool. Read More
