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

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

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

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

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

Goat milk holds malaria vaccine

The latest episode of the Animal Science Podcast from the American Society of Animal Science interviews researcher Mark Westhusin at Texas A&M University which recently announced the birth of a genetically modified goat that produces a malaria vaccine in its milk. This goat could help people in ... 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

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

Capturing viruses with bacteria

When my laboratory discovered the cell receptor for poliovirus in 1989, many new research directions were suddenly revealed – such as creating a mouse model for poliomyelitis. One application we did not think of was to use the receptor to screen samples of drinking water for the presence of viru... Read More

Bacteria Talk, Plants Listen: The Discovery of Plant Immune Receptors, an Interview with Dr. Pamela Ronald

Prof. Pamela Ronald, a Professor in Plant Pathology at University of California, Davis and director of Grass Genetics at the Joint Bioenergy Institute, studies genes that control the plant response to stress.

In her presentation for the Frontiers in Life Sciences symposium at Cornell Universi... Read More

Sick People Smell Bad: Why dogs sniff dogs, humans sniff humans, and dogs sometimes sniff humans

A man can live many lives. Paul Ehrlich has. Once, he was a butterfly biologist. Another time, he wrote the book called The Population Bomb, a book that triggered global conversations about the fate of humanity. Still another, he described the relationship between plants and the animals that eat... Read More

A spike for piercing the cell membrane

Some viruses that infect bacteria (bacteriophages) deliver their DNA into the host cell with an amazing injection machine. The tailed bacteriophages (such as T4, illustrated) store their DNA in a capsid attached to a long tail tube that is surrounded by a sheath. At the bottom of the tube is a b... 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

High School Senior Presents Poster At American Society for Microbiology 112th General Meeting (press release)

Kathleen Maguire, a Marlborough High School Senior, is presenting a poster at the American Society for Microbiology (ASM) Conference in San Francisco on June 16-19. In order to attend the conference, Maguire became a special member of the society. She is the first high school student to have a p... Read More

Discovering novel viruses in insect vectors using metagenomics

I listen to TWiM and perhaps this story (from mine ha!) will be of interests. A nicely written microbiology blog talking about two papers that use metagenomic sequencing on viruses in insect vectors: mosquitoes (animal viruses) and whitefly (plant viruses)

Not only did we find known human an... Read More

Bacteria ‘munching’ on Titanic: scientists

In less than 30 years, there may be nothing left of the Titanic but a heap of “rusticles,” warns researcher Henrietta Mann, who has spent four years researching bacteria gnawing on its sunken hull.

A scientific expedition in 1991 to the disintegrating wreck some 12,400 feet (3,780 meters) to ... Read More

Harmful Bacteria Can Be Curbed With Copper

Salmonella enterica is a leading cause of diarrhea illness worldwide, according to Sadhana Ravishankar, an assistant professor in the University of Arizona department of veterinary science and microbiology.

Each year the tiny, rod-shaped species of bacteria with a love for rapid reproduction ... Read More

House Of Natural Fiber's Intelligent Bacteria At The New Museum
