Intense exercise can cause problems with our digestive tract. It even has a name — "Exercise-induced Gastrointestinal Syndrome." Simply put, strenuous exercise can damage the gut and let the bacteria that reside there potentially pass into the bloodstream.
While some researchers look for drugs to treat HIV, other scientists delve deep into the virus itself for answers on how it causes infections.
Despite legends to the contrary, it appears that the saliva of a Komodo dragon is not teeming with pathogenic bacteria that kills their prey. Its reputation to survive while colonized with lots of horrible disease-causing bacteria, true or untrue, has made it the subject of research in pursuit of natural antimicrobial agents and led scientists to some remarkable findings.
Gonorrhea infections reached a peak in 1975, then decreased until 2009, when infection rate started rising and has increased each year since. With the rise of antibiotic resistance, those numbers are only going to get worse — unless we find new treatments against the bacteria.
For younger children, a day at the playground is not complete without some sandbox time. Long a favorite of children and parents, sandboxes could also be sheltering dangerous pathogens.
News: Scientists Are Using the Special Physics of Dragonfly Wings to Create Surfaces That Shred Bacteria on Contact
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.
Bacteriotherapy sounds a lot more amenable of a term than "fecal transplant," yet they're both treatments that use bacteria itself to cure or treat infections. Fecal transplants, specifically, are an up-and-coming treatment option for a potentially deadly and difficult-to-treat diarrheal infection called Clostridium difficile.
News: Hospital Floors May Look Clean, but They're Teeming with Deadly Superbugs—Including MRSA, VRE & C. Diff
Hospitals are places we go to get well, and we don't expect to get sick or sicker there. But a study from researchers at the Cleveland Clinic, Case Western Reserve University School of Medicine, and Cleveland VA Medical Center in Ohio found that hospital floors in patient rooms were frequently contaminated with healthcare-associated pathogens—often dangerous multi-drug resistant bacteria.
If you have a taste for sweets, you have at least one thing in common with mosquitoes. While too much sugar is unhealthy for humans, a new product makes sweets deadly to mosquitoes.
Phuket, the island in Thailand typically associated with paradise and most recently, illegally-run hotels, now has a different problem—a stray cat with the claws of death.
In the summer of 1976, 4,000 American Legionnaires descended upon the Bellevue-Stratford Hotel in Philadelphia, Pennsylvania, for a four-day convention. Several days later, many of the attendees experienced symptoms of severe pneumonia. By the beginning of August, 22 people had died. The Centers for Disease Control and Prevention (CDC) estimate that about 180 people were sickened and 29 people died before this mysterious outbreak burnt out.
Every year, 100-200 people in the US contract leptospirosis, but usually 50% of the cases occur in Hawaii where outdoor adventurers are exposed to Leptospira bacteria found in freshwater ponds, waterfalls, streams, and mud. That's why it's so alarming that two people in the Bronx have been diagnosed with the disease and a 30-year-old man has died from it.
A state of emergency has been declared in Malaysia's northeastern Kelantan state after an outbreak of avian influenza virus H5N1.
Add antibiotics to the possible list of culprits responsible for honeybee decline around the world. While it may come as a surprise, antibiotics are commonly mixed into feed used by commercial beekeepers to maintain their hives. In a recent study published in PLOS Biology, researchers from the University of Texas at Austin found antibiotics used to treat honeybees may be a contributing factor in individual bee death and colony collapse.
Termite poop and biofuels — what's the connection? New research into termites' intestinal comings and goings describes a process that may speed the development and lower the cost of fuels made from plant matter.
Everything from disposed of drugs to hormones and disease-causing bacteria — anything that is rinsed or flushed down the drain — can contaminate wastewater.
You can get eggs and high-quality compost from backyard chickens—but you can also get Salmonella.
The herpes simplex virus (HSV) can cause devastating complications for infected newborns whose mothers have genital herpes. Understanding risk and research can help you, and your baby, when the time comes.
Yes, bubonic plague—the Black Death that killed millions in the Middle Ages— is still out there. It even infects and kills people in the United States. Without treatment, half the people infected die, but the Food and Drug Administration approved ciprofloxacin in 2015 to treat plague, and it has just successfully been used to stop the infection in five people.
Bed bugs are brown and creepy. Could you spot one in your hotel room? A new study reveals most people are freaked out by bed bugs, but only about 35% could identify one.
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.
Bioluminescence — the ability of an organism to produce and emit light — is nature's light show. Plants, insects, fish, and bacteria do it, and scientists understand how. Until now, though, we didn't know how fungi glow.
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.
The food TV chefs prepare make our mouths water. From one scrumptious creation to another, they fly through preparation without frustration or error. They make us think we can do the same with similar ease and delectable, picture-perfect results. Some of us have noticed, though, that these TV chefs don't always adhere to the same safe food handling guidelines we've been taught to follow.
We all know you are what you eat—or so the expression goes—but it's good to remember that what you are (at least intestinally) is mainly bacteria. A new study has shown that what you eat, and how your gut microbiome reacts to that food, might be a key player in your risk of developing a certain type of colon cancer—and changing your diet can help decrease your risk.
The ability of one microbe to adapt is giving it a whole new career as a sexually transmitted disease. Usually content with the back of the throat and nose of those who carry it, the dangerous pathogen Neisseria meningitidis has adapted to cause an illness that looks a lot like gonorrhea.
News: We've Found the Back Door HIV Uses to Hide in the Brain—& It Could Help Us Take the Virus Down
Over 1.2 million people in the US are infected with human immunodeficiency virus (HIV)—and one out of eight of them don't know it. Even after decades of intense research into the virus, there's still no cure for it. One of the big problems is that the virus hides out in certain cells of the body, resisting treatments that kill it.
Being a city dweller does not mean you cannot save the planet — or your food scraps. Climate change and resource management are big issues. Composting in any size space is not only possible, but it gives you a chance to reduce greenhouse gasses and reuse food scraps. Right now, about 40% of all food in the US goes to the landfill. In addition to planning meals and using your food in creative ways to reduce the amount that goes to waste, you can compost.
Rabbits have been a persistent problem in Australia for over 150 years. Now the Peel Harvey Catchment Council (PHCC) and Peel-Harvey Biosecurity Group have released a strain of the rabbit haemorrhagic disease virus (RHDV), called RHDV1 K5, to reduce the number of pests in the Murray region of New South Wales.
Despite the availability of a vaccine against it, almost 50% of men aged 18-59 in the US are infected with the human papillomavirus (HPV). Why?
The Deepwater Horizon oil spill that began on April 20, 2010, was the largest maritime oil spill in history. Killing 11 people and discharging 4.1 million barrels of oil and natural gas into the Gulf of Mexico, the event was an unparalleled personal, environmental, and business disaster. It was also the first major oil spill to take place in the deep ocean.
Wherever there are people, the party is sure to follow. Well, a party of microbes, at least. That is what scientists at NASA's Jet Propulsion Laboratory have found after a 30-day microbial observation of the inflatable lunar/Mars analog habitat (IMAH).
Findings from a mouse study suggest that the Zika virus infection may have serious reproductive consequences for men.
While it is easy to create and maintain your compost pile, you can enjoy it more knowing a few basic tips.
Andre was enjoying the carefree life of a 12-year-old with his friends, riding his bike and playing sports, like all kids that age. Schoolwork wasn't hard for him, and his grades showed that.
How can a drug used to treat cancer be effective against viruses, too? The answer lies in the drug's shared target — specifically, cellular components that control the activity of genes. A new research study showed that one such type of drug, histone methyltransferase inhibitors used in cancer clinical trials, has activity against herpes simplex virus, too.
For the first time, the US Food and Drug Administration (FDA) has approved medication to treat children with a serious infection called Chagas disease, which stealthily infects and damages the hearts of millions of victims a year.
The office of your physician, or your local hospital, is where you go when you need medical care. But it could also be where you could pick up a life-threatening infection.
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.
New research explores how the bacteria on the penis can leave men more susceptible to infection with HIV.
