Fauci: Robust Research Efforts Needed to Address Ongoing, Global Challenge of Antimicrobial Resistance

Given the evolutionary ability of microbes to rapidly adapt, the threat of antimicrobial resistance likely will never be eliminated. Today, many factors compound the problem, including the inappropriate use of antibiotics and a dwindling supply of new medicines, leading to a global crisis of ant... Read More

Scientists build man-made 'living-materials' inside bacterial cells

Our bones are remarkable feats of engineering; strong and yet light, shot through with holes and yet able to bear incredible loads. This super-strong natural material is built as cells incorporate hard minerals like calcium into living tissue. Now, scientists at the Massachusetts Institute of Te... Read More

Five new Listeria species found; may improve tests

Cornell researchers have discovered five new species of a group of bacteria called Listeria – including one named for Cornell – that provide new insights that could lead to better ways to detect soil bacteria in food. To date, of the 10 previously known species of Listeria, only two are pathogen... Read More

Twenty-six lectures in virology

In the spring of each year I teach a virology course to undergraduates and masters students at Columbia University. I produce video recordings of all my lectures not only for students in the course, but for anyone else who is interested in learning about viruses.

You can find my virology lect... Read More

1 in 25 patients gets infection in hospital

When antibiotics first started being used in the 1940's they were considered a "miracle drug". It seemed that bacterial infections would no longer be a problem for the world. However, recently, one gene is making it seem as though the end of antibiotics is at hand. This gene is New Delhi metallo... Read More

Resurrecting ancient microbes to understand evolution

When you hear the word “resurrection”, what’s the first thing that comes to mind? Religious miracles? Zombie viruses? The end of the world?

Whatever your mental association, I’m willing to bet it’s not “an emerging scientific discipline." Well, it just so happens a growing community of microb... Read More

One in 25 patients battling hospital-acquired infections: CDC

On any given day, one in 25 hospitalized patients - 4 percent - is battling an infection picked up in a hospital or other healthcare facility, according to a new survey by the Centers for Disease Control and Prevention (CDC).

That translates to more than 600,000 hospital patients each year. R... Read More

Catheter Innovation Destroys Dangerous Biofilms

For the millions of people forced to rely on a plastic tube to eliminate their urine, developing an infection is nearly a 100 percent guarantee after just four weeks. But with the help of a little bubble-blowing, biomedical engineers hope to bring relief to urethras everywhere.

About half of ... Read More

Researchers Find Rising Incidence of Patients Admitted With Infections Resistant To Common Antibiotics

The emergence of community-acquired infections, such as urinary tract infections (UTI), due to strains resistant to common antibiotics are on the rise, according to Rhode Island Hospital researchers. The study is published online in the journal Antimicrobial Resistance and Infection Control.

Breastfeeding increases prevalence of Lactobacilli and Bifidobacteria in infants

Breastfeeding until at least nine months of age increases prevalence in the gastrointestinal tract of Lactobacilli and Bifidobacteria, species which are known to contribute to development of a healthy immune system, according to a paper describing the establishment of the intestinal microbiota d...

Small peptides as potential antibiotics

Small peptides attack bacteria in many different ways and may well become a new generation of antibiotics. Biologists at the Ruhr-Universität Bochum (RUB) have been researching how such peptides kill bacterial cells. "It is quite possible that, in ten years time, all of the currently marketed an...

Canadian man in hospital with Ebola-like virus

A man is in hospital in Canada with symptoms of a haemorrhagic fever resembling the Ebola virus, a health official has said.

The man had recently returned from Liberia in the west African region, currently suffering a deadly outbreak of an unidentified haemorrhagic fever.

He is in isolatio... Read More

New 'gut bacteria' clinical study could help reduce side-effects of radiotherapy

Researchers will examine the role of gut bacteria in influencing the side-effects patients experience after radiotherapy, in the first clinical study of its type.

The study will be carried out by researchers at The Institute of Cancer Research, London, and The Royal Marsden NHS Foundation Tru... Read More

Scientists develop world’s first light-activated antimicrobial surface that also works in the dark

Researchers at UCL have developed a new antibacterial material which has potential for cutting hospital acquired infections. The combination of two simple dyes with nanoscopic particles of gold is deadly to bacteria when activated by light - even under modest indoor lighting. And in a first for ... Read More

Researchers find way to reduce E. coli in cows, improving food safety

A new biological treatment could help dairy cattle stave off uterine diseases and eventually may help improve food safety for humans, a University of Florida study shows.

Kwang Cheol Jeong, an assistant professor in animal sciences and UF’s Emerging Pathogens Institute, examined cattle uterin... Read More

TB or not TB: that is the question.

Tuberculosis (TB) represents a serious public health problem: 8.7 million cases in 2001 and over 1.4 million deaths per year. In 2006, extensively drug-resistant (XDR) tuberculosis has been confirmed in 84 countries, heralding the possibility of virtually untreatable tuberculosis. The emergence ... Read More

New childhood TB cases double earlier estimates

esearchers from Harvard-affiliated Brigham and Women’s Hospital (BWH) and Harvard Medical School (HMS) have estimated that around 1 million children contract tuberculosis (TB) annually — twice the number previously thought to have the disease and three times the number of cases diagnosed every y...
