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.
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.
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.
Rising on the world stage, dengue fever is transmitted by mosquitoes — and apparently air travel too.
After years of telling patients to finish any prescribed course of antibiotics completely, a group of researchers in the UK say it is no longer necessary, and could even be harmful if we want to preserve the antibiotics we can still use.
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.
Staphylococcus aureus is a widespread bacteria — about a third of us have it on our body right now — usually in our nose or on our skin. And it probably isn't causing an infection. But, about 1% of people who have Staphylococcus aureus present have a type that is resistant to the antibiotic methicillin.
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 didn't expect.
Malaria is a massive worldwide health problem. The Centers for Disease Control and Prevention estimate that 212 million cases of malaria occurred worldwide in 2015 and 429,000 of the infected people died.
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.
With a death rate of one in five, sepsis is a fast-moving medical nightmare. New testing methods might improve your odds of survival if this infection ever hits you.
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 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.
Montezuma's revenge, the runs, the trots, or just diarrhea — everyone gets it sooner or later. What exactly is diarrhea good for, if anything?
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.
It's not always easy to get to the root of an infection outbreak. Epidemiologists study infected people, contacts, and carefully examine where the infections happened and when. In the case of a 2012 outbreak of pertussis — whooping cough — in Oregon, scientists just published an analysis of how vaccination status affected when a child became infected during the outbreak.
Despite the threat of superbugs, physicians continue to prescribe antibiotics when they might not be needed, and patients are suffering.
Significant strides have been in the race to find antibiotics to treat superbug infections — those caused by bacteria resistant to the antibiotics used to treat them. Now, an international team of scientists has discovered a new antibiotic produced by a microbe found in Italian soil.
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.
Move over whole wheat — white bread may be back in style after a new study shows that it may be your gut microbes that decide what kind of bread is best for you.
Dangerous to humans and dogs, Rocky Mountain Fever, along with several other tickborne infections, is on the rise.
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.
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.
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.
Fighting fire with fire, scientists are harnessing the adaptability of helpful microbes to challenge the adaptability of deadly microbes. What are we talking about? Hunting with phages — viruses that attack and kill bacteria.
Water makes up about 60% of your body weight. Whether you like it plain, flavored, bubbly, or in beverages or food, we all need water daily to avoid dehydration and stay healthy. For communities in need of clean drinking water, new research using bacteria may offer a simplified, lower-cost method for boosting potable water supplies.
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.
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.
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.
It's about time people acknowledged that judging drug users would do nothing productive to help them. In the US this week, two new programs are launching that should help addicts be a little safer: Walgreens Healthcare Clinic will begin offering to test for HIV and hepatitis C next week, and Las Vegas is set to introduce clean syringe vending machines to stop infections from dirty needles.
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.
Warning: If you are eating and for some reason still decided to click on this article, turn around now. Maui, Hawaii health officials have reported finding at least six cases of angiostrongyliasis, a parasitic lungworm that infects humans. Colloquially, it's known as rat lungworm disease. And if you think that name is awful, just wait until you hear what it does to the human body.
The squiggly guys in this article's cover image are Propionibacterium acnes. These bacteria live in low-oxygen conditions at the base of hair follicles all over your body. They mind their own business, eating cellular debris and sebum, the oily stuff secreted by sebaceous glands that help keep things moisturized. Everybody has P. acnes bacteria—which are commonly blamed for causing acne—but researchers took a bigger view and discovered P. acnes may also play a part in keeping your skin clear.
Two viral liver diseases could help us find the path toward the cause of Parkinson's disease. Researchers from the University of Oxford and UCL Institute of Neurology in London have reported an association between hepatitis B and C infections and an increased risk of Parkinson's disease. Their findings were published early online in the journal Neurology.
To keep fungal pathogens at bay in their crowded homes, wood ants mix potions to create powerful protection for their nest and their young.
For regions that experienced a boom in mouse populations last year, scientists say 2017 could see a surge in cases of Lyme disease.
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.
Over 6,500 waterfowl—mostly ducks—have died in Canyon County, Idaho, stricken by avian cholera. The outbreak started in February, and before it's over, it may not only be Idaho's largest outbreak, but one of the largest in the country.
