New Pills Deliver Bacteria, Not Drugs to Cure us

It seems that nearly every day, scientists connect another medical condition to atypical gut bacteria populations. Researchers have claimed that gut bacteria play a role not just in digestive health but even in basic brain function and mental health. Certain bacteria are so clearly good for us t... Read More

Rare bacteria outbreak in cancer clinic tied to lapse in infection control procedure

Improper handling of intravenous saline at a West Virginia outpatient oncology clinic was linked with the first reported outbreak of Tsukamurella spp., gram-positive bacteria that rarely cause disease in humans, in a new report from the Centers for Disease Control and Prevention (CDC). The repor... Read More

'Sterile' Urine May Be a Myth

Many people have heard that human urine is devoid of germs, but a new study seems to question that idea.

"Doctors have been trained to believe that urine is germ-free," Dr. Linda Brubaker, dean of Loyola University Chicago Stritch School of Medicine, said in a university news release. "These ... Read More

How Bacteria in Placenta Could Help Shape Human Health

The placenta is full of microbes, a new study finds, raising questions about how that ecosystem and mothers' oral health influence the risk of pre-term birth.

Even before a baby is born a microbial ecosystem takes up residence in the placenta, creating a microbiome that may help shape the new... Read More

You'll Want To Wash Your Hands Immediately After Reading This (Infographic)

Germaphobes, maybe you're on to something.

Sickness-causing bacteria and viruses can lurk on surfaces long after they're expelled in an infected person's sneeze or snot. Some can even stay on a surface for months, given the right conditions. While the ability of these microorganisms to actual... Read More

Bacterial food web may be key to cystic fibrosis

Cystic fibrosis patients suffer from chronic bacterial infections and thick mucous in their lungs, due largely to a combination of microbial infections and resulting inflammation. A common pathogen, Pseudomonas aeruginosa, which can lay dormant in healthy individuals, becomes virulent in the lun... Read More

Scientists for Science

Scientists for Science are confident that biomedical research on potentially dangerous pathogens can be performed safely and is essential for a comprehensive understanding of microbial disease pathogenesis, prevention and treatment. The results of such research are often unanticipated and accrue... Read More

Adoption of the fist bump as a greeting could substantially reduce the transmission of infectious disease between individuals

Could a fist bump be a cleaner, better way for people to greet each other, especially in germy hospitals? British researchers have done an experiment that seems to say yes.

They tested just how many bacteria are transferred hand to hand during a handshake, a high-five and a fist bump. Handsha... Read More

6.5% NaCl Media

Important ingredients: 6.5% salt, dextrose, bromcresol purple
Differential/Selective: used to test for salt tolerance and can be used to identify enterococcal group D streptococci. NaCl is a selective agent and those organisms that can grow in higher salt concentrations also ferment the dextro... Read More

New Drugs Use Cell "Garbage Disposal" to Kill Bacteria

A new class of molecules called acyldepsipeptides—ADEPs—may provide a new way to attack bacteria that have developed resistance to antibiotics.

Researchers have discovered a way to increase the potency of ADEPs by up to 1,200 times. Their findings appear in the Journal of the American Chemica... Read More

TB bacteria mask their identity to intrude into deeper regions of lungs

TB-causing bacteria appear to mask their identity to avoid recognition by infection-killing cells in the upper airways. The bacteria call up more permissive white blood cells in the deeper regions of the lungs and hitch a ride inside them to get into the host’s body.

These findings are report... Read More

Physarum polycephalum

Physarum polycephalum, slime mold, grown in a large perti plate on moist paper towels using oatmeal as the food source. Culture was grown in the dark at room temperature. The paper towel was moistened every day with tap water. After 3 week’s the culture formed sporangia (fruiting bodies). Im... Read More

Stanford University Bioengineer Creates Organic Microbe-Powered Video Games

Bioengineer Ingmar Riedel-Kruse of Stanford University has created a series of games where players control organic microbes.

The games, which you can see showcased in the video below, places a collection of single-celled protozoans called paramecia in a thumbnail-sized chamber with electrode-... Read More

In Search of the Perfect Gut Microbiome with a Tribe of Tanzanian Hunter-Gatherers

It might sound strange to say that humans have forgotten what human-food is, but many scientists believe this is the case. For thousands of years, the environment in which humans lived evolved at a glacial pace—our nutrition and culture changed slowly, and our bodies adapted to it at a matching ... Read More

E.coli on MacConkey Agar (Mac)

Streak plate isolation of E. coli on MacConkey Agar grown for 24 hrs at 37 degrees. E. coli demonstrates strong lactose fermentation indicated by the bright pink halo, bile precipitant around the colonies, and pink colony growth. Read More

Small microbes almost killed all life on Earth, study suggests

Tiny microbes on the bottom of the ocean floor may have been responsible for the largest extinction event our planet has ever seen, according to a new study.

These microbes of death were so small, that 1 billion of them could fit in a thimble-full of ocean sediment, and yet, they were almost... Read More
