The incidence of tuberculosis (TB) is dropping in the US, but the World Health Organization (WHO) considers it to be epidemic in the rest of the world — there were over 10 million new cases in 2016.
We can add one more health effect of our gut bacteria to the growing list. Researchers from the UK have just reported that the gut microbiota plays a role, both directly and indirectly, on the toxicity and efficacy of chemotherapy. Their findings are published online in the journal Nature Reviews Gastroenterology & Hepatology.
The community of bacteria that lives in our gut has a lot to tell us. It can give clues to what we eat, the environment we live in, and diseases and disorders we may have. Now, scientists have linked these bacterial species to how we feel. A new research study found an association between women's gut bacteria and their emotions.
Some types of bacterial infections are notoriously tough to treat — and it's not all due to antibiotic resistance. The bacteria themselves are rugged and hard to penetrate with drugs.
Colorectal cancer — cancer of the colon or rectum — is the third most commonly diagnosed cancer in the US. To reduce the chances of a diagnosis we are all urged to stop smoking, keep our weight down, decrease our intake of alcohol and red meat, keep active, and get screened for colon cancer. But, new research has found something that participates in the development of colorectal cancer that might not be as easy to control: A strep bacteria that promotes tumor growth.
As fun as it is to see Fido's face light up when you feed him table scraps, American dogs are getting fat. The good news is that research is homing in on nutritional strategies to boost canine capabilities to maintain a healthy weight.
Sourdough is a delightful twist on your traditional bread, but creating and maintaining a sourdough starter can be a headache for many home bakers.
The bacteria in our gut — a community called the gut microbiome — have been in the spotlight a lot lately. What we're learning about how our intestinal bacteria adapt and grow with our bodies could help athletes perform better, according to researchers starting a company focused on creating probiotics that mimic athletes' microbiomes.
Not all bacteria in the eyes cause infection. A group of researchers from the National Eye Institue has shown that not only is there a population of bacteria on the eyes that reside there but they perform an important function. They help activate the immune system to get rid of bad, potentially infection-causing — pathogenic — bacteria there.
A rose by any other name may smell as sweet, but one annoying invasive weed may hold the answer to treating the superbug MRSA. Researchers from Emory University have found that the red berries of the Brazilian peppertree contain a compound that turns off a gene vital to the drug-resistance process.
Most females have had at least one urinary tract infection in their lifetimes. Recurrent UTIs are particularly problematic in young, sexually active women, where about 80% of the infections are caused by the bacteria Escherichia coli, better known as E. coli.
Yogurt is more than an excellent source of protein, calcium, and gut-healthy probiotic bacteria. A protein isolated from probiotic lactobacillus bacteria in yogurt is capable of inhibiting drug-resistant bacteria.
Cholera may be rare in the US, but cases of the disease have increased worldwide since 2005, particularly in Africa, southeast Asia, and Haiti. An estimated 3 to 5 million people are infected, and more than 100,000 die from the disease globally each year, mostly from dehydration.
Bacteria gets a bad rap. Most headlines focus on the danger and discomfort posed by pathogens like bacteria, but many of the bacteria that live on and in us are vital to our health. Many products out there, called probiotics, are sold with the implication that they're supporting these healthy bacteria that share our bodies — but do they actually work?
Cytochrome P450 (P450s) are proteins found in nearly all living organisms, which play roles that range from producing essential compounds and hormones to metabolizing drugs and toxins. We use some of the compounds synthesized by P450 in plants as medical treatments, but the slow growth and limited supply of these plants have put the drugs' availability in jeopardy and jacked up prices.
Some bacteria can already do it—generate electric current, that is—and those microbes are called "electrogenic." Now, thanks to the work of a research group from the University of California, Santa Barbara, we know how to easily turn non-electrogenic bacteria into electricity producers.
New weapons are needed to combat antibiotic-resistant bacteria. Instead of drugs, scientists have discovered in an animal study that they may be able to harness vampire bacteria to vanquish pneumonia.
Whether your palate runs to domestic or imported, a piece of cheese can be a real treat for the senses. Its smell, taste, and texture are all parts of its appeal. A big part of what makes that savory wonderfulness comes from the microbes in and on the cheese. Thanks to a team of researchers dedicated to studying those microbes, we have a better understanding of their importance to cheese and us.
New research reveals how E. coli bacteria construct elaborate and effective tunnels to pump unwanted molecules like antibiotics and other toxins out of cells. The discovery could help us better understand how antibiotic resistance occurs and give us a leg-up to beat them at their own game.
For many of us, pets are important family members. They give us loyalty, companionship, and comfort. Now, researchers have given us another reason to welcome them into the family: Babies from families with furry pets — the majority of which were dogs — had higher levels of two types of beneficial gut bacteria.
As drug-resistant bacteria become more commonplace, researchers are looking for new antibacterial strategies to disrupt disease-causing microbes. Some scientists are working to create new drugs, while others are trying out drug combinations. Another group, however, are ditching pharmaceuticals altogether and experimenting with non-drug alternatives.
Most people know atopic dermatitis by its common name, eczema—that dry, flaky skin that itches incessantly. Along with the scratching comes frequent skin infections, often with Staphylococcus aureus.
Where in the world did it come from? All of a sudden, one day, someone had an infection with flesh-eating bacteria. It captured headlines and worldwide attention because it was such a severe, strange, uncontrollable, and really disgusting condition.
Scientists know that bacteria create their own energy, get nutrients to run their cellular processes, and multiply. But, bacteria haven't been shown to respond to external mechanical stimulation or signals in a way that's similar to how our bodies respond to touch, until now.
While at work, you notice your gloves changing color, and you know immediately that you've come in contact with dangerous chemicals. Bandages on a patient signal the presence of unseen, drug-resistant microbes. These are ideas that might have once seemed futuristic but are becoming a reality as researchers move forward with technology to use living bacteria in cloth to detect pathogens, pollutants, and particulates that endanger our lives.
As researchers learn more and more about our intestinal bacteria—also called the gut microbiome—we're finding out that these microbes aren't just influencing our health and wellness, they're a useful tool for improving it, too.
What do Leo Tolstoy (writer), Beethoven (composer), Paul Gaugin (artist), and Adolf Hitler (politician) have in common? They are all considered to have suffered from the sexually transmitted disease syphilis.
As a lover of food, I'm often asked, “If you could only have one food the rest of your life, what would it be?” My answer is always the same: sourdough bread. (Okay, it's not always the same... I usually cheat and say sourdough, fancy cheese, and a good beer.) Admittedly, I'm biased by my own sentimentality. My mother is an expert bread baker, with a major in making sourdough. Her sourdough starter is older than I am, and in all honesty, she's made thousands of loaves, each better than the ne...
In this tutorial, we learn how to grow bacteria with agar and petri dishes. First, prepare your agar by swirling it and then pouring it into an open petri dish. Next, close the cap to the petri dish and let it sit for an hour. Next, grab a q-tip and swab it on a surface you prefer. After this, swab it onto the petri dish and let it sit for around a week. When you come back to the dish, you will see all the bacteria that has grown! This is a great science experiment to do for children in schoo...
Peach trees and other related plants are susceptible to the devastation caused by fire blight, a contagious bacterial disease. Once contracted, infected trees have to be burned to contain the disease and prevent spread to nearby trees. Increasing resistance to antibiotic treatment has sent scientists in search of alternative ways to deal with the bacteria and prevent its catastrophic damage.
When Chan Mei Zhi Alcine chose her senior project, she thought outside the box by thinking inside the bottle. Along with a research team at her university, she found a way to combine health and enjoyment, while meeting a challenge not so definitively met before in alcoholic beverages. She and a research team at her university claim they've created the world's first probiotic sour beer.
Our quest to find new antibiotics has taken a turn — a turn down the road, that is. A team of scientists from the University of Oklahoma is scooping up roadkill and searching for bacteria on them that might yield the world's next antibiotic.
Using extreme time-lapse microscopy, scientists watched a virus take over a bacteria to create a cell that looked and functioned more like a plant or animal cell. True story.
No one can dispute the evolutionary success of bugs. The oldest insect fossils were found encased in crystallized mineral silica in Scotland in 1926, and they're between 396 and 407 million years old.
A terrifying antibiotic-resistant superbug, one thought to only infect hospital patients, has made its debut in the real world. For the first time ever, the superbug carbapenem-resistant Enterobacteriaceae (CRE) infected six people who hadn't been in or around a hospital in at least a year, and researchers aren't sure how they got infected.
Have you ever wondered what makes a healthy vagina? Bacteria play an important role in vaginal health. If you've ever had your vaginal microbiome—the bacterial community that lives in your vagina—wiped out by taking antibiotics, you probably are well aware of that.
Makeup brushes accumulate a lot of bacteria and dirt. Keeping your makeup brushes clean should be an important part of your makeup routine. And it doesn't have to take very long. Julieg713 has some great advice on how to deep clean your makeup brushes efficiently. Deep cleaning makeup brushes is recommended at least once a month to keep your brushes in top form and bacteria-free.
Plants all around us capture sunlight every day and convert it to energy, making them a model of solar energy production. And while the energy they make may serve the needs of a plant, the process isn't efficient enough to generate power on a larger scale. So, scientists from the University of California found a way to treat bacteria with chemicals that turned them into photosynthesis machines, capable of generating products we can convert into food, fuels, and plastics.
Urinary tract infections (UTIs) drive over eight million people to seek medical attention every year. Almost all — as many as 90% — of those infections are caused by Escherichia coli. Copper can kill bacteria, but E. coli has found a way to capture the copper, preventing its antibacterial action. Now, researchers have found that, in a cruel irony, the bacteria use the copper it grabs as a nutrient to feed its growth.
A promising new antibiotic has been discovered in, of all things, another bacteria. Burkholderia bacteria live in diverse habitats, including soil, plants, and humans where they thrive by knocking out other microbes that compete with them for resources or threaten their existence. Scientists have discovered they accomplish this by producing a very effective antibiotic.
