As if the swollen, painful joints of rheumatoid arthritis weren't enough, the disease is the result of our immune system turning against cells of our own body. Ever since this realization, scientists have worked to find the trigger that sets the immune system off. Scientists believe that gut bacteria may have a role in initiating the abnormal immune response. Now, a team of researchers from Boston has figured out how that might occur.
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.
New research explores how the bacteria on the penis can leave men more susceptible to infection with HIV.
Foodborne infections often occur through the contamination of equipment, food-prep tools, and unsanitary surfaces. A recent report from the Centers for Disease Control and Prevention (CDC) reminds us that breast pump parts are part of the food-delivery chain — and they can become contaminated too.
A week into my internship, I experienced pretty serious back pain and slight difficulty breathing. I scheduled a doctor's appointment to make sure nothing was wrong, and I got a surprising diagnosis: bad posture.
About a third of the methane released into the environment comes from the production and transport of natural gas. The gas leaks as it moves along the transport chain from gas wellheads to market.
Heart disease is the leading cause of death of men and women in the US. Over half a million Americans die from it annually. Atherosclerosis — a build up of plaque in the arteries — is a common feature of heart disease and can be caused by smoking, fats and cholesterol in the blood, diabetes, and high blood pressure.
It is not just a bad summer for ticks — it has been a bad decade for the spread of tick-borne infections. New surveillance from the CDC reports rapid expansion and increase in cases of babesiosis, a sometimes life-threatening disease, in Wisconsin.
Look no further than Flint, Michigan, to discover the serious consequences of contaminated drinking water. Around the world, water polluted by pathogens and toxins sickens people or cuts them off from safe drinking water. Looking for a solution, researchers created tiny, swimming robots that pack a powerful punch against waterborne pathogens.
Bone loss and belly fat may no longer be certain fates of menopause, thanks to new research from an international team of scientists.
Despite the threat of superbugs, physicians continue to prescribe antibiotics when they might not be needed, and patients are suffering.
If you know that ticks spread Lyme disease, you may already know you might also catch a bunch of other infections from them. One of the lesser-known diseases spread by ticks is infection with the bacterium Anaplasma phagocytophilium, called anaplasmosis.
Alzheimer's disease — an irreversible, progressive brain disorder — is the sixth leading cause of death in the US and more than afflicts 5 million Americans. As if those numbers aren't scary enough, the Centers for Disease Control and Prevention expect that number to nearly triple by 2050.
Legionnaires' disease is named after 1976 outbreak in Philadelphia that sickened 221 people and killed 34. More often striking adults over the age of 50, the Centers for Disease Control and Prevention (CDC) recently reported two cases where newborns contracted the often fatal disease — at their moment of birth.
Citrus greening disease — caused by a bacteria spread by psyllid insects — is threatening to wipe out Florida's citrus crop. Researchers have identified a small protein found in a second bacteria living in the insects that helps bacteria causing citrus greening disease survive and spread. They believe the discovery could result in a spray that could potentially help save the trees from the bacterial invasion.
We know that healthcare-related facilities can be fertile ground for antibiotic-resistant bacteria, but recent research suggests your produce aisle might be too.
Listeria monocytogenes bacteria don't play fair. Healthy people can usually handle the food-borne infection, but the bacterial infection hits pregnant women, fetuses and cancer patients very hard. Interestingly, a new study found that other bacteria may help prevent Listeria infections in those people.
The possibility of severe tickborne illness is increasing as an aggressive tick from the American southeast moves up the Atlantic Coast.
With summer just ahead, you, or your children, may be looking forward to some pool time or the water park. When planning water-based fun this year, keep a heads-up for microbes.
Even though the Ebola virus was discovered as recently as 1976, over 30,000 people have been infected since, and half have died a horrible death. Since there's no way to cure the infection, the world desperately needs a way to prevent it — and the five similar viruses in its family, the ebolaviruses.
Have you ever had a burning sensation when you urinate? Low fever, back pain, and maybe cloudy urine? Male or female, it could have been a urinary tract infection. If it lasted long enough, the chances are good you went to the doctor for help. For about 20% of women, standard testing for a UTI does not reveal the presence of infection-causing bacteria, even though bacteria may be causing their symptoms. Well, a new test may provide better answers.
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.
Pertussis, or whooping cough, is a highly contagious disease that can be life-threatening for young children. New research backs a recommendation that all pregnant women receive a pertussis booster with each pregnancy, as it can help their infants fight off the infection.
When just floating peacefully in the water with their brood mates, the Culex mosquito larvae in the image above does not look very frightening. But in their adult form, they are the prime vector for spreading West Nile virus — a sometimes mild, sometimes fatal disease.
Devastating and deadly, land mines are a persistent threat in many areas of the world. Funding to clear regions of land mines has been decreasing, but new research may offer a less dangerous method of locating hidden, underground explosives by using glowing bacteria.
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.
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.
Antibiotics used to prevent diseases in livestock are creating a world of hurt for humans and the soil we depend on for food. Bacterial resistance to antibiotics is a global health issue. The overuse, underuse, and poor use of these life-saving drugs is rapidly removing them as a treatment option for serious infections in humans—plus bacteria are naturally adaptive.
In the ongoing search to find better ways to use antibiotics, an extract made from maple syrup has some surprisingly important medical benefits.
Viral infections have been the focus of attention in the development of autoimmune diseases—diseases where the body's immune system reacts to the body's own cells—because they trigger the immune system into action.
An advance in the race to stop birth defects caused by Zika-infected mothers has been made by a team of researchers from Rensselaer Polytechnic Institute in Troy, New York. They have identified the process Zika uses to gain entry into the placenta, and published their findings in the journal Biochemistry.
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.
Yellow fever has emerged again in Brazil, causing death and disease to people unprepared for this mosquito-borne illness.
Have you ever had the stomach flu, aka the 24-hour flu? Well, chances are high that you never had influenza, but an intestinal infection called gastroenteritis.
Even as health authorities describe the symptoms of Zika infection in the general population as mild, a new surveillance study finds serious side effects are more common, and serious, than previously thought.
By looking for the mechanism that allows influenza A to invade lung cells, scientists also discovered a treatment that might block the virus from taking hold there.
Seagrass may help your favorite beach stay a little less toxic. A new study, led by Joleah Lamb, a postdoctoral researcher in the Harvell Lab at Cornell University, found that coastal seagrasses reduce levels of pathogens dangerous to humans and marine organisms in near-shore waters.
The pathogen referred to as a "nightmare bacteria" is quietly adapting and spreading faster than anticipated.
You know the signs—sneezing, fever, nagging cough, no energy, no appetite. It's the flu, but this time, it's your dog who's down and out. Yes, dogs get the flu, too. However, a team from the University of Rochester Medical Center and their collaborators have developed a new vaccine that may make the doggy flu a thing of the past.
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.
