The story of Helicobacter pylori is a real testament to the tenacity of medical researchers to prove their hypothesis. It took decades before the scientific world would accept that the bacteria H. pylori caused ulcers.
Winter moths (operophtera brumata) can be a nuisance to your trees during early spring time. The biggest concern is the larva, which is a caterpillar/inch-worm feed on the budding leaves of deciduous trees and you won't really notice it until your leaves are at their full size. A good way to get rid of the moths is with a bacterium called, BT (bacillus thuringiensis)or Spinosad a derivative of a bacterium. If you have really big trees, you may need to get an arborist to treat your trees.
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...
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.
The number of households in the US that go hungry because they lack money for food hit a high of almost 15% in 2011. While that number continues to decline, nearly 13% of American households still go hungry.
Cytochrome P450 (P450s) are proteins found in nearly all living organisms, which play roles that range from producing essential compounds and hormones to metabolizing drugs and toxins. We use some of the compounds synthesized by P450 in plants as medical treatments, but the slow growth and limited supply of these plants have put the drugs' availability in jeopardy and jacked up prices.
Mitochondria are known as the powerhouses of our cells because they generate energy to power them. But they also play a key role in the death of cells when they're damaged, infected, stressed, no longer needed, or at the end of their life.
Drug-resistant bacteria have made curing some infections challenging, if not nearly impossible. By 2050, it's estimated that 10 million people will be dying annually from infections with antibiotic-resistant organisms.
Growing populations and higher temperatures put pressure on world food supplies. Naturally occurring soil bacteria may save crops in drought-stressed areas, put more land into crop production, and produce more food.
The rate of preterm birth has been increasing in the United States for unknown reasons, causing increased health risks for infants born too soon. But researchers may have found a signal that could help doctors plan ahead for, or even prevent, early birth with a simple swab of the vagina and cervix during pregnancy.
A tiny louse is responsible for decimating the citrus industry. Diaphorina citri, the louse in question, better known as the Asian citrus psyllid, harbors and spreads the "Candidatus Liberibacter asiaticus" bacteria that causes citrus greening disease.
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.
What do Leo Tolstoy (writer), Beethoven (composer), Paul Gaugin (artist), and Adolf Hitler (politician) have in common? They are all considered to have suffered from the sexually transmitted disease syphilis.
With more and more movies being released in 3-D, it's important to remember a little thing called bacteria. If you want to be free of another person's germs, then you need to think about those 3-D glasses. They're prime targets for bacteria and need to be cleaned properly.
Air conditioning systems are cold and wet and make great breeding grounds for bacteria and mold, and adding a nasty odor to the air coming out of the vents.
In this tutorial, we learn how to detect and avoid bad breath. If your mouth is very dry, it's going to smell worse and worse. The more oxygen and moisture that you have in your mouth, the less bacteria will be inside it. For people with halitosis, they have a big problem with bad breath. Bacteria lives in your tongue, so you can't scrape them away. You can take a test to see how bad your breath is with a machine. After you do this test, you can learn how to keep more hydrated. Once you have ...
-It is very important that you choose the right counter top. Although granite and marble may look good, they are not kind to the environment because they are mine deep out of the Earth.
Unfortunately, the very places we go to receive health care put us at risk for becoming infected with superbugs, bacteria exposed to so many antibiotics that they have become immune to their effects. Clostridium difficile (C. diff) is one such bacteria. It causes inflammation of the colon and rampant diarrhea that can have life-threatening consequences. Part of its virulence lies in the tough spores formed by the bacteria. They are responsible for starting infections in the colon and for spre...
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.
Streptococcus and staphylococcus bacteria produce toxins that can cause toxic shock syndrome.
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.
Arsenic occurs naturally in the environment, but it is also one of the most commonly found heavy metals in wastewater, deposited there by inappropriate disposal and arsenical pesticides, for example.
Scientists are constantly on the search for new organisms, species, and other types of life. A special group of these researchers, calling themselves "bioprospectors," dive deep into mines to find unique lifeforms with special properties not found anywhere else.
There's no shortage of ways to filter water, but it doesn't get much simpler than this. Researchers at MIT have found that you can turn dirty water into drinking water with nothing more than a stick.
A hungry tick is a determined little bugger—it wants to find its way into your skin if it’s the last thing it does. Here’s how to make sure it is the last thing it does.
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.
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."
Wound infections don't usually enter the blood and become systemic, spreading the infection throughout our bodies, and there's a good reason for that: Our bodies actively work to prevent it, according to research that discovered a new use for a protein first discovered decades ago.
The bacteria Klebsiella pneumoniae is a bad actor known for being antibiotic-resistant and causing a variety of serious infections in hospitals, including pneumonia, surgical site wounds, and meningitis. K. pneumoniae is something you do not want to encounter if you have a compromised immune system.
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.
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.
Usually, the mucus lining of the female genital tract presents a barrier that helps prevent infections. But, somehow, the bacteria that causes gonorrhea gets around and through that barrier to invade the female genital tract.
Having a Clostridium difficile infection means stomach pains, diarrhea, fever, and loss of appetite, and if the symptoms weren't bad enough, the disease often reoccurs. Now, new research has found an increased risk of recurrence in people who take medication to treat their stomach acid, gastroesophageal reflux disease, peptic ulcer disease, or stomach discomfort.
A dangerous bacterial disease is infecting dogs in northern New Jersey, forcing owners to keep their pets inside.
According to the National Safety Federation (NSF), pet bowls and toys carry coliform bacteria, including Staph bacteria, yeast, and mold. Additionally, an (unscientific) survey from Petco found that almost one-third of pet owners do not know the extent of contamination that their pet toys contain.
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.
A bacterium which triggers respiratory disease has been detected in the water systems of two Pennsylvania nursing facilities.
Antibiotic use in infants has been associated with a host of childhood conditions later in life. Yet when an infection is suspected in a newborn, usually a sample of their blood is drawn to check for the presence of bacteria and 5 to 8 percent of them receive antibiotics while the diagnosis is pending.
New research suggests the bacteria that causes listeriosis may be a bigger threat in early pregnancy than previously thought. Usually considered a danger to late pregnancy, scientists suggest early undiagnosed miscarriages could be caused, in some cases, by infection with Listeria.
There are all kinds of theories—many supported by science—about what causes Alzheimer's disease. Tangles of protein called ß-amyloid (pronounced beta amyloid) plaques are prominently on the list of possible causes or, at least, contributors. An emerging theory of the disease suggests that those plaques aren't the problem, but are actually our brains' defenders. They show up to help fight an infection, and decades later, they become the problem.
