Recently researchers from the University of Pennsylvania School of Dental Medicine discovered that, in many cases, early childhood caries result from dental plaque that contains both bacteria and fungus working together to make the biofilm on the teeth more pathogenic and difficult to remove. Now ...

Scientists at Wake Forest Baptist Medical Center found that eating a plant-based diet enhanced the good bacteria living in the gut by up to 7 percent as compared to only 0.5 percent from eating a more meat-centric, Western diet. Using an animal model, the research team designed the study to mimic ...
Before their research, scientists believed the tick somehow regurgitated the spirochetes from its midgut and the bacterium entered the host through the tick's salivary glands. Scientists assume that antibodies created following an infection waited in a host's body to provide immunity for specific strains of the ...
Drinking alcohol may change the bacteria in your mouth. A new study suggests that regular, heavy drinking can change the very microbiome (i.e., the collection of various microorganisms that reside in the body) of your mouth—and not in a good way. Researchers found that drinkers generally had less ...
There's a new not-so-great side effect of too much alcohol. It can change the balance of good and bad bacteria in your mouth and that can lead to other significant health problems. Researchers at New York University School of Medicine found more bad bacteria in the mouths of people who routinely drank ...

Recently researchers from the University of Pennsylvania School of Dental Medicine discovered that, in many cases, early childhood caries result from dental plaque that contains both bacteria and fungus working together to make the biofilm on the teeth more pathogenic and difficult to remove. Now they ...
By Sam Wong. A curious hybrid of a red blood cell and an E. coli bacterium could make an ideal transporter for carrying drugs inside the body. Drug treatments often have side effects by causing changes elsewhere in the body, prompting researchers to hunt for clever ways to package drugs and target ... bacteria cancer
The decaying plant materials are digested by a certain bacteria that thrives in oxygen-poor environments. Those bacteria, called anaerobic bacteria, are prevalent in the sulfur-rich soils of that area. They produce carbon dioxide and hydrogen sulfide, which gives off the tell-tale sulfur smell. While the odor ... bacteria cancer
If anything makes us human it's our minds, thoughts and emotions. And yet a controversial new concept is emerging that claims gut bacteria are an invisible hand altering our brains. Science is piecing together how the trillions of microbes that live on and in all of us - our microbiome - affect our physical ... bacteria cancer
Humanity might not go out with a bang, but a sniffle – at least if the terrifyingly-plausible "superbug" scenario comes to pass. As bacteria increasingly evolve resistance to antibiotics, we could be cast back into "the dark ages of medicine" in the next few decades. But now we might have a new way to fight ... bacteria cancer
Bacterial vaginosis affects one in three women at some time. According to Dr Corne Brink, gynaecologist and obstetrician from Fourways Life Hospital in Johannesburg, it is a bacterial infection caused by a shift in the normal balance of bacteria in the vagina. Brink says that 50 – 75% of women with bacterial ... bacteria cancer
THURSDAY, April 19, 2018 (HealthDay News) -- The makeup of bacteria in your dog's digestive tract may be more like your own than you think, researchers say. In a new study, investigators analyzed gut bacteria populations ("microbiomes") in two dog breeds. The findings showed that the genes in the dogs' microbiomes ... bacteria cancer
The problem is that not all bacteria are willing to cooperate and make only measly amounts of protein. Only a few bacteria end up making enough of the proteins to be useful, and, until now, there has been no way for researchers to know if a bacterium they're working with will be a hit or a dud. "One of the ... bacteria cancer
The plastic bottles we throw away today will be around for hundreds of years. It's one of the key reasons why the mounting plastic pollution problem, which is having a deadly effect on marine life, is so serious. But scientists recently discovered a strain of bacteria that can literally eat the plastic used to make ... bacteria cancer
“Importantly, we did not prove that the bacteria deposited by hand dryers are responsible for disease,” he told Healthline. “In fact, for people with a healthy immune system, it is unlikely to be a problem as the hand dryer is concentrating environmental bacteria from the air probably found in most places ... bacteria cancer
I have become smitten with bacteria. I enjoy the company of yeasts, too, and enzymes, for the work they do in converting energy from one form into another and, especially, making alcohol out of carbohydrates and sugar. Brewers and winemakers, of course, would be knee-deep in sweet fruit juice and sticky ... bacteria cancer

In E.B. White's classic children's story Stuart Little, the eponymous mouse lives happily with a New York City family. But Dr. Ian Lipkin wanted to know whether cohabiting with a mouse may be hazardous to one's health. So Lipkin and his colleagues at the Columbia University Mailman School of ...
The natural world is rapidly becoming a giant pile of plastic waste. There are literally six—six!—ungodly large garbage patches swelling in the ocean. Even areas as far removed from us as the Arctic are not safe. We're slowly suffocating a lot of natural ecologies with our trash. Fish, birds, and other animals ...
While you've been freaking out over individual headlines suggesting that a tiny amount of fecal bacteria is lurking on your hands or faucets or what-have-you, those studies have been amassing into a whole body of research that shows pretty definitively that bacteria from our poop is absolutely everywhere.
A team from Princeton University has developed a more efficient method to treat toxins found in sewage, fertilizer runoff and other forms of wastewater. Sewage plants use bacteria to remove the environmental toxins from wastewater so clean, processed water can be safely discharged into oceans and ...
The study began by examining germ-free mice, with no intestinal bacteria. These mice with no gut bacteria were fed high-fat diets yet they did not gain weight. Instead they were found to be excreting the fats in their stool. A second type of mouse model was then studied. Called "specific pathogen free (SPF)," these mice were ...
The bacteria the team has experimented with is a non-pathogenic marine bacterium classified as a “hydrocarbonoclastic,” meaning a bacterium which uses hydrocarbons as a source of energy. This particular bacterium is already present in oceans, where it drifts with currents. When it comes into contact ...
In the chill of deep space, bacteria somehow shielded from cosmic radiation might survive dormant for millions of years. .... This may sound ambitious, but at least one natural organism, a bacterium called Deinococcus radiodurans, has a DNA-repair mechanism that can rebuild genes correctly after heavy ...
They say that more research is needed to find out whether the hand dryers are simply doing a good job of blowing this bacteria towards your hands or if the nozzle itself might be harbouring bacteria. Either way, they note in the paper that “paper towel dispensers have recently been added to all 36 ...
Campylobacter is the most common cause of bacterial food poisoning in the world according to the World Health Organization, and with over a million people in the U.S. infected every year, it's not surprising that there is a need to understand why this spiral-shaped microbe causes disease. The bacterium ...
Philippe Horvath, a soft-spoken food scientist who went to work for a French chemical company in 2000, was charged with identifying the best strains of bacteria for making the popular dairy product. Bacteria can be infected by viruses, just like humans and other living things, and Horvath was engaged in a ...
Although the vast majority of research on the gut microbiome has focused on bacteria in the large intestine, a new study -- one of a few to concentrate on microbes in the upper gastrointestinal tract -- shows how the typical calorie-dense western diet can induce expansion of microbes that promote the ...
You don't need to be alive for your microbiome to be useful to science. After years of studying the populations of bacteria on living people, researchers are now turning their sights on the dead. And they're finding that the "postmortem microbiome" is useful not only for forensic investigations, but also for ...

The truth is that most bacteria aren't bad for us. Microbes are essential to life on Earth. They were some of the earliest life-forms, before us oxygen-sniffing creatures even set foot on the planet. Today, they're an essential part of our own immunity. They even interact with and, at times, control our genes, feeding our brains ...
Researchers used biochemical and genetic assays to track resistant strains of bacteria in Japanese travelers returning from Vietnam. The researchers found short trips to a developing country can lead to the appearance of the colistin-resistance gene mcr-1. The study highlights that even brief international ...
To do so, they examined 36 bathrooms across the campus. They were specifically scanning the areas for bacteria colonies and a lab-engineered strain of bacteria called Bacillus subtilis or PS533, often found in soil. Using a special plate, they powered on the dryers for 30 seconds to find out which bacteria ...
As it turns out, bacteria may have been trying to help all along. A. borkumensis is commonly found in all oceans around the world, and populations tend to skyrocket in oily waters – which is a good thing, since the microorganism eats many of the hydrocarbons found in oil. The INRS team studied the ...
"The cell wall is the structural entity that encases the entire bacterium, and its health is critical for the survival of the bacteria. If you have a drug that inflicts damage to the cell wall, the bacterium cannot cope with it and it dies." P. aeruginosa is one of the "nightmare bacteria" highlighted in a recent report from ...
But B. subtilis wasn't alone; the plates exposed to hand dryers hosted "a variety of flora" — 62 types of diverse bacteria representing 21 species, including Staphylococcus aureus, a common bacterium that is part of the normal microbiome but which is also associated with serious infections, according to the ...
Caltech scientists have created a strain of bacteria that can make small but energy-packed carbon rings that are useful starting materials for creating other chemicals and materials. These rings, which are otherwise particularly difficult to prepare, now can be "brewed" in much the same way as beer.
In recent years, researchers have sequenced the genomes of thousands of bacteria from various sources. Research associate Dr.Tarek Rouissi poured over "technical data sheets" for many bacterial strains with the aim of finding the perfect candidate for a dirty job: cleaning up oil spills. He focused on the ...
Researchers at Harvard Medical School, the University of California, San Francisco, and the University of Georgia have described how the protein that allows strep and staph bacteria to stick to human cells is prepared and packaged. The research, which could facilitate the development of new antibiotics, ...

New research reveals details of the mechanism by which the bacterium Wolbachia blocks viruses in mosquito cells, suggesting that it reduces viral replication inside cells and that rapid degradation of viral RNA is involved. Professor Scott O'Neill, Program Director of the World Mosquito Program, led by ...
Chemically tweaking a sugar molecule known as trehalose lets it slip inside the bacteria that causes tuberculosis (TB) and glow. The method offers a quick, simple way to detect the pernicious bug, and may help counter TB, a deadly lung infection that's particularly common in developing countries. Howard ...
MEMPHIS, Tenn. -- A WREG investigation revealed dangerous and potentially deadly germs lurking in plain sight. NewsChannel 3 teamed up with researchers from the University of Memphis School of Public Health to test for bacteria on common surfaces. "We wanted to check, you know what is the total ...
In fact, having a high percentage of this type of bacteria means that your skin is healthy. Researchers have found that people with certain skin conditions like eczema often have less of this type of bacterium and more of another, called Staphylococcus aureus. There are even trials going on now to see if reintroducing S.
Scientists go to great lengths to ensure that they aren't introducing terrestrial bacteria into the Martian environment when they send rovers there. NASA even has an Office of Planetary Protection dedicated to making sure life on Earth doesn't contaminate the pristine environment of other planets. This limits ...
Dubbed DMN-Tre, the hybrid molecule stays dark until it enters a fatty, water-repellant layer in a TB bacterium's cell wall, where it starts to glow, researchers report online February 28 in Science Translational Medicine. Standard tests use dyes that stain a bunch of different bacteria, so technicians have to ...
