Exposure to cigarette smoke has long been associated with increased frequency of respiratory infections—which are harder to treat in smoke-exposed people than in those who lack such exposures. Now Ritwij Kulkarni of Columbia University, New York, NY, and colleagues show that cigarette smoke actu... Read More

Bacteria that live in the soil seem to be swapping antibiotic-resistance genes with other, more dangerous bacteria — the ones that cause devastating infections in humans, a new study indicates.
When a team of researchers analyzed bacteria they had grown from soil samples, they found the microbe... Read More

Stomach ulcers could have handed in their chips - thanks to the humble potato.

Scientists at Manchester University have discovered spuds contain unique antibacterial molecules that can treat the condition.

Members of the university’s microbiology team now hope the substance, dubbed ‘pota... Read More

The use of a commonly prescribed antibiotic is a major contributor to the spread of infection in hospitals by the ‘superbug’ MRSA, according to new research. The study also found that increasing measures to prevent infection – such as improved hygiene and hand washing – appeared to have only a s... Read More

The impact of influenza on work absenteeism is poorly documented. Researchers used data from the national registry and Norway Post AS (>14,000 employees) to explore sickness absence patterns from 2005/06 through 2009/10 in Norway. Annually, an estimated 2.868% (mean 95% confidence interval (CI):... Read More

Heavy metals and other toxins frequently contaminate food and water. The culprits read like a litany of bad actors—lead, cadmium, mercury, arsenic, chromium—but their numbers run into the thousands. Microbes have long been enlisted for bioremediation, but they also have the potential to protect ... Read More

A new species of bacteria living 1,200 metres deep at freezing temperatures in the Bay of Bengal is all set to solve the universal problem of lactose intolerance in human beings. Lactose is a type of sugar present in milk. Two-thirds of people around the world cannot digest lactose, which may ca... Read More

New research may help explain why hundreds of thousands of Americans a year get sick – and tens of thousands die – after bacteria get into their blood. It also suggests why some of those bloodstream infections resist treatment with even the most powerful antibiotics.

In a new paper in the Jou... Read More

Over the past fifteen years, Internet technology has significantly changed the landscape of public health surveillance and epidemic intelligence gathering. Disease and outbreak data is disseminated not only through formal online announcements by government agencies, but also through informal cha... Read More

Two chicken vaccines have recombined to produce more virulent viruses in Sydney and Melbourne, research has found, prompting the regulator to examine new controls over the approval and use of veterinary vaccines.

A study by a team from the Asia-Pacific Centre for Animal Health at the Universi... Read More

Three decades ago, some companies began adding a chemical called triclosan to their products and tried to convince consumers that their hand soap or toothpaste was better because it was “anti-bacterial.”

Now, scientists are finding traces of that compound in the environment, and it’s causing ... Read More

We've all been there. The holidays are approaching and there's that one person on our list for whom we have no idea what to give. It's a common problem that is usually resolved with the purchase of a gift card from a local retailer. From hardware stores to electronic shops to the bookstore, cons... Read More

We are teeming with microscopic life. Scientists recently reported on the billions of bacteria and fungi that grow inside us, finding a lot of diversity from person to person — and from spot to spot on the human body.

Those findings were in 242 young adults (ages 18 to 40) in exceptionally go... Read More

Researchers Jose Cordova of Yale University and Erich Astudillo of Chile’s Universidad de Santiago discovered a molecule they call Keep 32 that kills the bacteria responsible for all the trauma you suffered as a child, lying down blinded by the light as a masked man poked bits of metal in your m...

I recently returned from the ASM yearly general meeting in San Francisco. It happens to be 60 years, no less, since I attended my first such event, that one in Chicago. In those days, many members attended a giant banquet as part of the event, I well remember. As a poor graduate student, I could... Read More
