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 ...more

Acanthamoeba keratitis (AK), a rare eye infection caused by the Acanthamoeba ameba found in tap water, affects a few dozen people in the US every year. In some cases, it can have devastating effects, like what Irenie Ekkeshis has experienced; She was blinded by AK in her right ...more

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. New research may have solved that problem. A group of researchers from the University of Ill ...more

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? Today, we associate malaria with trop ...more

The problem with HIV is that it attacks and kills the very cells of the immune system that are supposed to protect us from infections — white blood cells. But a new technique, developed by scientists at The Scripps Research Institute (TSRI) in La Jolla, California, offers a di ...more

As summer mosquito season approaches, researchers are warning people with previous exposure to West Nile virus to take extra precautions against Zika. A new study found that animals with antibodies to West Nile in their blood have more dangerous infections with Zika than they ...more

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. Microbes, good and bad, predate and outnumber us. Humans will never "win" a ...more

More bad news for patients who have undergone heart surgery in the past five years. A new study suggests about one-third of heater-cooler units used in cardiac procedures remain contaminated with a slow-growing, potentially fatal bacteria. Heart failure is the leading cause o ...more

For regions that experienced a boom in mouse populations last year, scientists say 2017 could see a surge in cases of Lyme disease. Caused by bacteria transmitted through the bite of an infected tick, Lyme disease causes serious neurological symptoms if left untreated. While ...more

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 Br ...more

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 a ...more

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 T ...more

Mosquitoes are a big problem, and citronella candles are not the solution. There are a lot of mosquito species. The American Mosquito Control Association reports there are more than 3000 mosquito species in the world, and about 200 of those occur in the US. The most common ar ...more

As if being pregnant did not come with enough worry, a new study found that certain antibiotics are linked to an increased risk of spontaneous abortion, or miscarriage — a terrifying finding for any expectant mother. The study, published in the Canadian Medical Association Jo ...more

The search is on to find antibiotics that will work against superbugs — bacteria that are rapidly becoming resistant to many drugs in our antibiotic arsenal. By carefully choosing antibiotics that killed bacteria in different ways, a team of researchers found that combination ...more

On the airplane, in the middle of cold and flu season, your seatmate is spewing, despite the clutch of tissues in their lap. Your proximity to an infectious person probably leaves you daydreaming (or is it a nightmare?) of pandemics and estimating how likely it is that this se ...more

As researchers from Yale searched our environment for compounds to aid in the battle against drug-resistant bacteria, they got an unlikely assist from ticks. Ticks are best known for being the nasty bloodsuckers that spread dangerous infections like Lyme disease, the Powassan ...more

Flu vaccines can help prevent us from getting or suffering the most severe effects of the flu. But, each vaccine only protects us from three different strains of the flu. If we don't have a vaccine against all types of flu, it leaves us open for an epidemic with a flu virus we ...more

Even though HIV rates declined 18% between 2008 and 2014, 1.1 million people in the US are living with the infection. Part of that is because HIV is treatable, but not curable. HIV attacks the very cells of the immune system that should kill off the infection, and our bodies ...more

A gold-medal winning entry into the iGEM synthetic biology competition could change the way we look at Esherichia coli, the bacteria better known as E. coli. Often the culprit in food-borne disease outbreaks, E. coli is rarely congratulated for its good work. Recently, studen ...more

With the height of the flu season ahead, there are some good reasons to keep a flu vaccination in mind. In the United States, the flu season lasts from autumn through late-winter. As many people know, influenza, or the flu, is a contagious respiratory virus that targets the l ...more

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. In a study published in Science, led by senior author Dr. Ban ...more

Using mathematical modeling, researchers suggest weather and warming created the "perfect storm" that drove the Zika outbreak in 2016. Carried by mosquitoes, Zika is a Flavivirus first identified in Uganda in 1947 by scientists conducting research on yellow fever. Zika forest ...more

Most of us equate feeling cold with catching a virus—but we've also heard plenty of debunkers proselytizing that being cold isn't what gives you the flu. Still, we know that cold and flu season always falls during the winter, so exactly what is the relationship between winter ...more

Norovirus outbreaks occur all year long, but peak in the winter months, which means we are in the middle of norovirus season. But there's still time to protect yourself from the highly infectious bug. There's no vaccine for the virus that causes one to three days of misery—ab ...more
