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
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
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
In what seems like a plot straight out of a low-budget science-fiction film, scientists have revived a giant virus that was buried in Siberian ice for 30,000 years — and it is still infectious. Its targets, fortunately, are amoebae, but the researchers suggest that as Earth's ice melts, this cou... 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
Bacteria have evolved resistance to every known class of antibiotic, creating an urgent need for methods to identify new antibiotics that work by different mechanisms. We have developed a new approach to antibiotic discovery that provides a short cut for identifying antibacterial molecules and ... 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
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
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
Many experts believe that chronic fatigue syndrome (CFS) has several root causes including some viruses. Now, lead scientists Shara Pantry, Maria Medveczky and Peter Medveczky of the University of South Florida’s Morsani College of Medicine, along with the help of several collaborating scientist...

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
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
A newly discovered fungus that feasts on the skin of amphibians is threatening to decimate a species of salamander in the Netherlands, according to new research.
Fire salamanders are one of the most recognizable salamander species in Europe, and are characterized by their distinct yellow- and... Read More
The presence of male sperm and seminal fluid causes female worms to shrivel and die after giving birth, Princeton University researchers reported this week in the journal Science. The demise of the female appears to benefit the male worm by removing her from the mating pool for other males.

Not so long ago, most people thought that the only good microbe was a dead microbe.
But then scientists started to realize that even though some bugs can make us sick and even kill us, most don't.
In fact, in the past decade attitudes about the bacteria, fungi, viruses and other microbes l... 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
A new way to attack flu viruses is taking shape in laboratories at Rutgers University, where scientists have identified chemical agents that block the virus’s ability to replicate itself in cell culture.
These novel compounds show promise for a new class of antiviral medicines to fight much-f... Read More
