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.
Whether or not a microbe is successful at establishing an infection depends both on the microbe and the host. Scientists from Duke found that a single DNA change can allow Salmonella typhi, the bacteria that causes typhoid fever, to invade cells. That single genetic variation increased the amount of cholesterol on cell membranes that Salmonella and other bacteria use as a docking station to attach to a cell to invade it. They also found that common cholesterol-lowering drugs protected zebrafi...
Type 1 diabetes is an attack on the body by the immune system — the body produces antibodies that attack insulin-secreting cells in the pancreas. Doctors often diagnose this type of diabetes in childhood and early adulthood. The trigger that causes the body to attack itself has been elusive; but many research studies have suggested viruses could be the root. The latest links that viruses that live in our intestines may yield clues as to which children might develop type 1 diabetes.
Just like your gastrointestinal tract, and the soil we walk on — a dust storm has a collection of bacteria, fungi, and viruses all its own called a "dust microbiome."
The beauty of southern Europe won't protect it from invasions of disease-carrying ticks and mosquitoes—in fact, the Mediterranean climate and landscape may be part of the reason the bloodsuckers are expanding there, bringing unique and terrifying diseases in their wake.
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.
To much of the United States, Zika seems like a tropical disease that causes horrible problems in other countries but is nothing to be worried about stateside. It may make you rethink your beach vacation abroad, but not much more than that. However, if you live in Florida or Texas, the possibility of getting a Zika infection where you live is real — and local outbreaks are more and more a possibility.
A vaccine against HIV might prevent the disease that we can't seem to cure. Some HIV patients make antibodies that can take down the virus, much the way a vaccine might. But, scientists haven't been able to provoke that type of response in other people. However, in a process that might work in humans, a group of researchers has successfully generated antibodies in cows that neutralize multiple strains of HIV.
Bacteria, viruses and other germs sometimes set off the immune system to overreact, producing a severe condition called sepsis. Sepsis is so dangerous that it is the leading cause of death of children across the world, killing a million kids every year, mostly in developing countries. Probiotic bacteria might be able to prevent sepsis and infections, but no large research studies have been done to find out whether that actually works. Until now.
A recent study offers information that might help combat a deadly virus that affects an estimated 300,000 people each year in West Africa.
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.
An older man dies of Zika. A younger man who cares for him catches Zika — but doctors cannot pinpoint how the disease was transmitted. While proximity to the patient is sufficient explanation for the rest of us, for microbe hunters, it is a medical mystery. Why? Zika is not known to transmit from person-to-person casually.
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.
Coronaviruses are common viruses, and most of us catch one at some point — they cause about 30% of all common colds. A new accidental discovery could help fight these viruses, even the deadlier, emerging ones.
The number of Legionnaires' cases in New York over the last couple weeks has led to concern and recommendations of caution for those at risk.
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.
While Lyme disease can be disabling, the wrong treatment for the infection can be fatal.
Most of us have already had an encounter with the Epstein-Barr virus, or EBV, for short. As part of the herpes family, it's one of the most common disease-causing viruses in humans. We get the disease with (or without) some nasty symptoms, then we recover. However, EBV stays in our body after the illness has ended, and it's one of the few viruses known to cause cancer.
Dengue fever is a danger to anyone living or visiting tropical or subtropical regions. It can be hard to detect the infection in its earliest and most treatable phase, especially in children. Luckily, new research highlights better techniques for triaging the disease in infected children with more severe symptoms, potentially saving lives.
In the worst measles outbreak in the state since 1990, the Minneapolis Department of Heath races to contain the spread of an infection believed to have originated from an infected traveler. Mistaken attitudes and unvaccinated travelers are creating a world of hurt and disease for Americans. A recent study found that more than half of eligible travelers from the US are electing to skip their pre-trip measles vaccine.
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.
Every party has a pooper, and that's why you're reading this article. We don't mean to be a downer on such a fun day as 4/20, but it's important to make sure you know about the source of your pot, especially if you're one of the 2,299,016 people who use medical marijuana in the US.
Although their effectiveness is waning, antibiotics remain a front-line defense against many infections. However, new science reveals using the wrong antibiotic for an infection could makes things much worse.
It hasn't even been eight years since Candida auris was discovered—cultured and identified from the ear canal of a patient in Japan—and now it's drug-resistant, setting up residence in hospitals, killing patients, and wreaking havoc across the globe.
Specialized cells in the lining of the gut may provide a key to preventing an infectious brain disease caused by misfolded proteins.
You might feel the bite, you might not, but an infected mosquito has injected you with a parasite named Plasmodium falciparum, a single-cell protozoa that quickly takes up residence in your body.
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.
Most people are familiar with the decline of honeybee colonies around the world. Among other threats, Colony Collapse Disorder (CCD) is eroding the capability of honeybees to maintain their hives and provide their services to human farmers.
While no longer native to the United States, hospitalization from malaria occurs in this country more than most would believe. Why is that, and what can you do to protect yourself when you travel abroad to regions where malaria is active?
Cats give us so much—companionship, loyalty, love... and now the bird flu. Several weeks ago, a veterinarian from the Animal Care Centers of New York City's Manhattan shelter caught H7N2 from a sick cat. According to a press release from the NYC Health Department on December 22, "The illness was mild, short-lived, and has resolved." This isn't the first time cats have passed infections on to humans, but it is the first time they passed on the bird flu—avian flu H7N2, to be exact.
Memorial Day signifies the unofficial kickoff for outdoor activities like camping. Camping can either be a flurry of fun and adventure, or a miserable few days of getting sick in the bushes and being dehydrated. Every summer, thousands of people set out on these camping adventures, and every summer, many become stricken with food borne illnesses or a parasitic infection. Watch this how to video to keep this from happening to you.
This video shows you how to make a wet mount that will determine if a person has yeast infection.
Growing evidence suggests that neurodegenerative diseases like Parkinson's may develop in part due to environmental factors, including infections that can cause inflammation in the nervous system. New research from investigators from Jude Children's Research Hospital and Thomas Jefferson University has strengthened that connection.
A recent case of Powassan virus has been reported in Saratoga County and may have been the cause of the infected patient's death. It's the 24th case in New York State since 2000, and will be reported to the CDC tomorrow, the NY Department of Health told Invisiverse. The tick-borne illness has no vaccine or specific treatments and can damage the nervous system.
In the race to outsmart "untreatable" antibiotic-resistant gonorrhea, one of the three new treatments on the track is about to enter Phase 3 clinical trials. Hopefully, it'll be widely accessible sooner rather than later, for the 78 million people who are diagnosed with gonorrhea each year.
Natural remedies used through the ages abound, especially in Asian medicine. The willow-leaved justicia plant, found throughout Southeast Asia, has traditionally been used to treat arthritis, but scientists have just discovered it contains an anti-HIVcompound more potent than AZT. AZT was the first drug approved to treat HIV, and is still used in HIV combination therapy today.
A new case of the still-mysterious Bourbon virus was confirmed in Missouri, likely originating within the state, local authorities said in a June 30 press release.
Streptococcus and staphylococcus bacteria produce toxins that can cause toxic shock syndrome.
Dramatic new research may change the fate of the hundreds of people who wait for a kidney transplant every year. The study hinged on the ability to cure hepatitis C infections, a possibility that became a reality in 2014.
After a brief reprieve, Zika fear is back with a vengeance as the US mosquito population booms. And we're just now seeing the true impact of this devastating virus, as babies of mothers infected with the virus are being born.
