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

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 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

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

New influenza A virus found in bats

Influenza A virus reservoirs in animals have provided novel genetic elements leading to the emergence of global pandemics in humans. Most influenza A viruses circulate in waterfowl, but those that infect mammalian hosts are thought to pose the greatest risk for zoonotic spread to humans and the ... 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

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

Potential New Treatment Identified for Leishmaniasis

Researchers at the College of Life Sciences have identified fexinidazole as a possible, much-needed, new treatment for the parasitic disease visceral leishmaniasis.

Leishmaniasis is named after William Leishman, a Glasgwegian doctor serving with the British Army in India, who first identified... Read More

Bean bugs found to harbor bacteria that keep them safe from an insecticide

Conventional wisdom says that in order for a species of insect to develop resistance to an antibiotic, several generations have to pass, whereby genes from those that have some natural resistance pass them on to their offspring. But sometimes conventional wisdom fails to take into account how so... Read More

Virus Find Helps Mystery Disease Probe in Cambodia

The investigation of a mystery disease that has killed dozens of children in Cambodia is advancing after the discovery in patient samples of a virus that causes hand, foot and mouth disease.

The Institut Pasteur du Cambodge found enterovirus 71 in 15 of 24 patients sampled since mid-June, Phi... Read More

CDC says C. difficile infections at “historic high”

It’s become a sad fact that many people being treated in health-care facilities end up catching a bad -- and potentially deadly -- bug in the very place where they’re supposed to get better.

A report on the increased incidence of clostridium difficile infections in hospitals and other health-... 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

Human gut bacteria seem to be picky eaters

People who eat a diet high in fats and animal protein tend to have a different group of bacteria flourishing in their gut compared with those who eat a mostly plant-based diet, researchers have found.

Researchers suspect that the microbes within us affect our vulnerability to infectious disea... 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.

How about using compost that includes road kill? I heard a billion pounds of animal byproducts go to landfills rather than into animal feed to prevent spread of mad cow disease. Compost that, too?

How Salmonella forms evil twins to evade the body's defenses

An unusual regulatory mechanism that controls the swimmer/non-swimmer option in genetically identical Salmonella also impacts the bacteria's ability to cause infection.

University of Washington scientists reported the discovery this week in the Proceedings of the National Academy of Sciences.... Read More
