Engineered Gut Bacteria Reverse Type 1 Diabetes in Experimental Mice

Scientists have managed to reverse type 1 diabetes (T1D) in experimental mice by giving the animals an oral course of harmless gut bacteria that had been engineered to secrete the whole proinsulin autoantigen (PINS) and the immunomodulatory human cytokine IL-10 (hIL10). An international team led... Read More

48% of Retail Chicken Contaminated with E. Coli

A recent test of packaged raw chicken products bought at grocery stores across the country found that roughly half of them were contaminated with the bacteria E. coli.

E. coli, which the study said was an indicator of fecal contamination, was found in 48 percent of 120 chicken products bought... Read More

Study Debunks Common Myth That Urine Is Sterile

Researchers have determined that bacteria are present in the bladders of some healthy women, which discredits the common belief that normal urine is sterile. These findings were published in the April issue of the Journal of Clinical Microbiology by researchers at Loyola University Chicago Strit... Read More

H5N1 Bird Flu Pandemic Potential Revealed

Two papers published this week, and one last month, reveal the pandemic potential of H5N1 "bird flu". One identifies four, another identifies five, genetic changes the virus would have to undergo before it could spread easily in humans, and the third paper suggests some of these changes are alre...

1 in 6 cancers worldwide caused by infections that can be prevented or treated

One in every six cancers worldwide is caused by an infection that is preventable or treatable, according to new estimates published in the journal Lancet Oncology. The research indicates infections are attributable for approximately 2 million new cancer cases every year.

"Infections with cert... Read More

The Race To Create The Best Antiviral Drugs

If you've ever had a bacterial infection like staph or strep throat, your doctor may have prescribed penicillin. But if you've had the flu or a common cold virus, penicillin won't work. That's because antibacterials only kill bacteria, and both the flu and the common cold are viruses. So for ill... Read More

Microbiology: Learning about who we are

Microbial inhabitants outnumber our body's own cells by about ten to one. These residents have become the subject of intensive research, which is beginning to elucidate their roles in health and disease.

Two journal articles by, David A. Relman, Departments of Medicine and of Microbiology and... Read More

A microbiology video game is being made, and needs your help on kickstarter

Bacillus is a video game named after the organism the developer studied in college. It's very different from other video games in that it features an accurate model for evolution. So accurate, every bacteria in the game has it's own genome (represented by A's T's C's and G's of course). But the ... Read More

Biofuel Research Boosted by Discovery of How Cyanobacteria Make Energy

A generally accepted, 44-year-old assumption about how certain kinds of bacteria make energy and synthesize cell materials has been shown to be incorrect by a team of scientists led by Donald Bryant, the Ernest C. Pollard Professor of Biotechnology at Penn State and a research professor in the D... Read More

Ultraviolet rays believed to prevent chickenpox spreading

Ultraviolet rays help prevent the spread of chickenpox, meaning people in milder climates are more at risk of catching the disease, according to new research. The discovery could lead to new ways of preventing chickenpox and its more severe relative, shingles.

A researcher at St George’s, Uni... Read More

Group urges speedier approvals for badly needed antibiotics

Infectious-disease doctors have proposed a speedier, easier approval process for drug companies developing antibiotics against untreatable illnesses.

Moffitt Cancer Center Researchers Discover How Cancer Cells “Hijack” a Mechanism to Grow

Researchers at Moffitt Cancer Center and colleagues at the University of South Florida have discovered a mechanism that explains how some cancer cells “hijack” a biological process to potentially activate cell growth and the survival of cancer gene expression.

Their study appeared in a recen... Read More
