MRSA Staph Strain Developed Drug Resistance in Your Burger: Research demonstrates the need to use antibiotics sparingly in food production, researchers say

A bacteria strain that causes a hard-to-treat staph infection probably developed its antibiotic resistance in food animals, a team of scientists announced Tuesday.

The strain of staph, known as methicillin-resistant Staphylococcus aureus, or MRSA CC398, most often infects farm workers who com... Read More

The microbiologist: Tweaking genes to help corals survive climate change

Kim Ritchie fell into coral research as an undergraduate, got a Ph.D. in genetics and was doing post-doctoral research in Panama when she lost her funding. With the ideal training for biotech, however, she slipped right into a startup. But when the company went bankrupt, she jumped back into res... Read More

Do Gut Microbes Travel From Person to Person?

It’s an exciting time for ecologists who study microbes. DNA sequencing has grown so cheap and fast that they can run around identifying bacteria living just about anywhere they can reach with a cotton swab. Turns out, bacteria are everywhere, even in the cleanest houses, and scientists are star... Read More

Discover Interview: Tullis Onstott Went 2 Miles Down & Found Microbes That Live on Radiation

Bacteria found in gold mines and frozen caves show the extreme flexibility of life, and hint at where else we might find it in the solar system.

The first time Tullis Onstott ventured underground, he squeezed into an elevator with dozens of South African gold miners and descended a mile into ... 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...

Flesh Eating Bacteria Makes Super Molecular Glue

The same bacteria that eats flesh can make a super glue used to bind molecules.

Dr. Mark Howarth, with his graduate student Bijan Zakeri in Oxford University's department of biochemistry, developed an adhesive that sticks molecules together, nearly inseparably.

They used the bacteria Strep... Read More

Explore the Human Microbiome [Interactive]

Learn about the bacteria, fungi and other micro-organisms that maintain human health.

The body contains 10 times more bacteria, fungi and other micro-organisms than human cells. Most of these species are harmless—although they can still cause illness if they wind up in the wrong place. In add... Read More

The Super-Resistant Bacteria That Has India 'Hell Scared'

Over 50 percent of bacterial infections in Indian hospitals are resistant to commonly used antibiotics, and surveys show that many widespread bacterial pathogens in India are also resistant to powerful, broad-spectrum antibiotics.

In 2010, a team of South Asian and British scientists analyzed... Read More

The Glowing Spider-Worms of New Zealand

Imagine you are a tiny caddisfly pupa. When you emerge from your pupal case, it is dark, but not pitch black, and high above you, you see the faint glow of a starry sky. On new wings, you rise. Cue angelic voices.

Suddenly, you struggle against an invisible barrier. Cue scary cello. You begin... Read More

New Infant Formula Ingredients Boost Babies' Immunity by Feeding Their Gut Bacteria

Adding prebiotic ingredients to infant formula helps colonize the newborn's gut with a stable population of beneficial bacteria, and probiotics enhance immunity in formula-fed infants, two University of Illinois studies report.

"The beneficial bacteria that live in a baby's intestine are all-... Read More

Zombie Bacteria - Lag Phase In Salmonella

Bacteria can multiply rapidly, potentially doubling every 20 minutes in ideal conditions but this exponential growth phase is preceded by a period known as lag phase, where no increase in cell number is seen. Lag phase was first described in the 19th Century, and was assumed to be needed by bact... Read More

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.

The Secret of Weight Loss May Be In 3,000-Year-Old Mummy Poop

Scientists may have found one of the keys to weight loss hiding in the poop of 3,000-year-old mummies. The bacterial DNA found in their guts is very different from our modern intestinal flora.

The reason: chlorinated water and antibiotics.
That's the first hypothesis of Dr. Cecil Lewis. Acco... 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.

Texas A&M center confronts antibiotic crisis with potential new bacterial treatment

It’s been called “the trots,” “Montezuma’s Revenge,” “the runs” and worse. But no matter the name, when it strikes, victims wish for a medicine that could go straight to the offending bacteria to quickly knock it dead.


That wish will ultimately come true if work by... Read More

Goat milk holds malaria vaccine
