University of British Columbia researchers have developed a vaccine that may halt the spread of West Nile Virus (WNV) among common and endangered bird species.
WNV, a mosquito borne pathogen, arrived in North America in 1999 and is now endemic across the continent. In 2012 alone, WNV killed 2... Read More
A form of malaria common in India, Southeast Asia and South America attacks human red blood cells by clamping down on the cells with a pair of proteins, new research at Washington University School of Medicine in St. Louis has revealed.
The study provides details that will help scientists des... Read More
It's a mould breaker. Researchers have discovered the first fungus that behaves like a farmer.
We already know that soil fungi can help bacteria travel quickly from A to B. The fungal filaments provide favourable conditions for the bacteria, and so act as "highways" through the soil. But thes... Read More
By tinkering with their chemical structures, researchers at the University of California, San Diego School of Medicine have essentially re-invented a class of popular antimicrobial drugs, restoring and in some cases, expanding or improving, their effectiveness against drug-resistant pathogens in...

Here I remember a person who a great deal of influence on my views about microbiology in the classroom, and the laboratory: the late Abigail Salyers. RIP, Abigail. Read More
Researchers at the Nanoscience Center (NSC) of University of Jyväskylä in Finland have developed a novel method to study enterovirus structures and their functions. The method will help to obtain new information on trafficking of viruses in cells and tissues as well as on the mechanisms of virus... Read More
Children hospitalized for pneumonia have similar outcomes, including length of stay and costs, regardless of whether they are treated with “big gun” antibiotics such as ceftriaxone or cefotaxime or more narrowly focused antibiotics such as ampicillin or penicillin, according to a Vanderbilt stud...

The system that allows the sharing of genetic material between bacteria – and therefore the spread of antibiotic resistance – has been uncovered by a team of scientists at Birkbeck, University of London and UCL.
The study, published today in Nature, reveals the mechanism of bacterial type IV ... Read More
Cast your minds back a few months ago, to when the director of the US Centers for Disease Control and Prevention announced, “We have a very serious problem” with “nightmare bacteria,” and the chief medical officer of the United Kingdom backed him up a few days later, describing a “ticking time b...

Circumcision drastically alters the microbiome of the penis, changes that could explain why circumcision offers protection against HIV and other viral infections. In a study to be published on April 16 in mBio®, the online open-access journal of the American Society for Microbiology, researchers... Read More
Finding that part of the story of Louis Pasteur's rabies vaccine is false, Héloïse Dufour and Sean Carroll explore how science fables are born, spread and die.
John Snow's ending of London's 1854 cholera outbreak, Joseph Lister's development of antiseptic surgery, Alexander Fleming's inventio... Read More
In an advance for HIV vaccine research, a scientific team has discovered how the immune system makes a powerful antibody that blocks HIV infection of cells by targeting a site on the virus called V1V2. Many researchers believe that if a vaccine could elicit potent antibodies to a specific conse... Read More
Researchers from AIST, in collaboration with the University of Montana (USA), the Open University of Japan, and others, have discovered that two types of bacteria with extremely reduced genomes endocellularly reside in a nested manner within the symbiotic organ of mealybugs that are known as agr...

Scientists at Emory Vaccine Center have found a link between immunity induced by vaccination and an ancient way that cells adapt to scarcity, a link that could help researchers develop vaccines against challenging infections such as HIV or malaria.
Researchers studying immune responses to the... Read More
Seafloor-dwelling bacteria may hitch a ride on methane bubbles seeping from deep-sea vents, preventing the methane from reaching the atmosphere by eating it up, new research suggests.
The findings, presented here today (Dec. 9) at the annual meeting of the American Geophysical Union, could he... Read More
Newcastle University scientists have revealed the mechanism that causes a slime to form, making bacteria hard to shift and resistant to antibiotics.
When under threat, some bacteria can shield themselves in a slimy protective layer, known as a biofilm. It is made up of communities of bacteria h... Read More
Nutrient enrichment and climate change are posing yet another concern of growing importance – an apparent increase in the toxicity of some algal blooms in freshwater lakes and estuaries around the world, which threatens aquatic organisms, ecosystem health and human drinking water safety.
As t... Read More
We’re driving on a dirt road and my interpreter, one of the friendliest guys I’ve ever met, is absorbed in a conversation with a health worker in our group. Cornfields and rice paddies paint the landscape chartreuse. Donkey carts and herds of goats swerve into the plants when we rumble past. The... Read More
At least eight people came down with listeria -- and one of them died -- after, authorities believe, eating "Hispanic-style cheese."
The Centers for Disease Control and Prevention on Friday reported the outbreak, which has affected people only of Hispanic descent and living in California or M... Read More
