‘SUPER-CLONE’ E. COLI COULD BE WORSE THAN HOSPITAL SUPERBUG

Virulent, drug-resistant forms of E. coli that have recently spread around the world emerged from a single strain of the bacteria, not many different strains, as has been widely believed.

The strain—which causes millions of urinary, kidney and bloodstream infections a year—could have a far gr... Read More

Attacking Fungal Infection, One of the World's Major Killers

Ask someone what the term ‘fungus’ brings to mind, and chances are it will be an image of something that smells or looks disgusting. Ask David Perlin, executive director of the Public Health Research Institute at Rutgers New Jersey Medical School, and the response will be far more somber – becau... Read More

Fuzzy Frosty

This smiling Frosty is no ordinary snowman—he's made entirely of mold.

The living artwork is the creation of Stephanie Mounaud, an infectious disease researcher at the J. Craig Venter Institute (JCVI) in Rockville, Maryland.

For the last several Christmases, Mounaud has used the different ... Read More

Malaria drug target raises hopes for new treatments

Scientists have taken an important step towards new malaria treatments by identifying a way to stop malaria parasites from multiplying.

In a study published in Nature Chemistry, they show that blocking the activity of an enzyme called NMT in the most common malaria parasite prevents mice from... Read More

A Call for Urgent Talks on Mutant Flu-Strain Research

The benefits and risks of "gain-of-function" research into highly pathogenic microbes with pandemic potential must be evaluated, scientists say. A group of over 50 researchers has called on the European Commission to hold a scientific briefing on research that involves engineering microbes to m... Read More

"Social" bacteria that work together to hunt for food and survive under harsh conditions (NSF Press Release)

When considering the behavior of bacteria, the word "social" doesn't often come to mind.

Yet some bacteria are quite social, chief among them Myxococcus xanthus, a soil-dwelling bacterium that organizes itself into multi-cellular, three-dimensional structures made up of thousands of cells tha... Read More

Anglers face dangers from vibrio vulnificus bacterium and fish handler's disease

When Charlie Schneider came back one day in June after being out fishing near his Tilghman Island home, he noticed he was getting chills. His left ankle itched and got worse and worse through the evening. It eventually started to throb a bit, and he couldn't sleep. At 2 a.m., he asked his wife t... Read More

The SOS response: how bacteria deal with damaged DNA

DNA is important stuff. It’s present in all living organisms on the planet (or ‘almost all’ if you wish to remain friends with virologists) and contains the information required to produce and organise the proteins within a cell. If the DNA is damaged, the cell will very quickly find itself in d... Read More

TB bacteria mask their identity to intrude into deeper regions of lungs

TB-causing bacteria appear to mask their identity to avoid recognition by infection-killing cells in the upper airways. The bacteria call up more permissive white blood cells in the deeper regions of the lungs and hitch a ride inside them to get into the host’s body.

These findings are report... Read More

New studies detail how HIV affects immune system, claim drug exists to block virus

In a last-ditch effort to rid the body of HIV, droves of white bloods cells self-destruct in an explosive mass suicide that drives the progression toward AIDS, a pair of new studies has found.

These fiery deaths attract more unsuspecting cells to come over and help, initiating a domino effect... Read More

Mating is the kiss of death for certain female worms

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.

Antimicrobial Properties

The emergence of antimicrobial resistance, coupled with the availability of fewer antifungal agents with fungicidal actions, prompted this present study to characterize Candida species in our environment and determine the effectiveness of virgin coconut oil as an antifungal agent on these specie...

Mutant Mosquito Virus May Serve as Vaccine for Deadly Disease

Eastern equine encephalitis virus, which kills about half of the people it infects, uses a newly identified mechanism to “hijack” cells of its hosts in order to suppress an immune response.

“Anytime you understand how a virus causes a disease, you can find ways to interrupt that process,” say... Read More

BCG vaccine more effective than previously thought

The BCG vaccine has been found to be more effective against the most common form of tuberculosis than previously thought, according to a new study in Clinical Infectious Diseases.

Bacillus Calmette Guérin (BCG) vaccine is included in the childhood vaccination programme of many countries, and ... Read More

HPV Home Tests Could Identify Cancer Risk

HPV self-testing is as effective as tests done by doctors, according to a Lund University study. Simple HPV home tests could therefore complement existing screening programmes, and identify more women at risk for cervical cancer.

Sweden has a system of regular gynaecological smear tests, whic... Read More
