Tardigrades are some of the toughest but least well-known creatures on our planet. These tiny animals, also called moss piglets or water bears, are definitely of this earth, but some can boast that they've also traveled to space.
Our canine best friends could spread our bacterial worst nightmare, according to a recent study. The problem with drug-resistant bacteria is well known. Overused, poorly used, and naturally adaptive bacteria clearly have us outnumbered. As science drives hard to find alternative drugs, therapies, and options to treat increasingly resistant infections, humans are treading water, hoping our drugs of last resort work until we figure out better strategies.
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.
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 Bronx have been diagnosed with the disease and a 30-year-old man has died from it.
During the millions of years they've been on earth horseshoe crabs have developed a trick that can save our lives even now — and may be especially useful in the fight against healthcare-associated infections.
News: Scientists Are Using the Special Physics of Dragonfly Wings to Create Surfaces That Shred Bacteria on Contact
As drug-resistant bacteria become more commonplace, researchers are looking for new antibacterial strategies to disrupt disease-causing microbes. Some scientists are working to create new drugs, while others are trying out drug combinations. Another group, however, are ditching pharmaceuticals altogether and experimenting with non-drug alternatives.
Deadly rat lungworm parasites have found their way into Florida. The parasitic worm relies on snails and rats to complete its life cycle, but don't let this nematode's name fool you. This worm can cause meningitis and death in humans who inadvertently consume snails, frogs, or crustaceans harboring the infective parasite.
If you have encountered bed bugs lately, you are not alone. While the pesticides used to fight these pests are losing effectiveness, a fungus shows promise in knocking the bugs out of beds everywhere.
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 are the Aedes, Anopheles, and Culex species. These are also the three mosquito species most likely to transmit serious illness, and all of them live in the US.
Like humans, cats can suffer infections caused by ticks, and too often, the disease is fatal. Learn about tickborne diseases that affect cats and what you can do to protect Fluffy from an untimely demise.
If you live with pets, you know where their tongue has been, yet you let them kiss and lick you all they want without even thinking twice about it. I've heard people say that a dog's mouth is very clean, and that their saliva, delivered by licking, can help heal wounds, but is that really true?
Despite legends to the contrary, it appears that the saliva of a Komodo dragon is not teeming with pathogenic bacteria that kills their prey. Its reputation to survive while colonized with lots of horrible disease-causing bacteria, true or untrue, has made it the subject of research in pursuit of natural antimicrobial agents and led scientists to some remarkable findings.
On June 11, 2016, an Arizona woman died from what appeared to be several infections, including pneumonia. She likely caught at least one of these from her dog.
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.
Our quest to find novel compounds in nature that we can use against human diseases —a process called bioprospecting — has led a research team to a small frog found in India. From the skin slime of the colorful Hydrophylax bahuvistara, researchers reported finding a peptide — a small piece of protein — that can destroy many strains of human flu and can even protect mice against the flu.
Bed bugs are parasites not yet known to spread disease — but they cause plenty of irritation. As scientists and landlords search for new ways to deal with the pests, a new study examines how we can deter bed bugs without so many chemicals.
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.
As summer heats up, new maps from the Centers for Disease Control and Prevention (CDC) gives us our best guess at where Zika-carrying mosquitoes could be hanging out this year in the US.
Bed bugs are brown and creepy. Could you spot one in your hotel room? A new study reveals most people are freaked out by bed bugs, but only about 35% could identify one.
A sometimes serious disease spread by fleas is making inroads in Texas, quietly doubling case numbers since 2008, and beginning to encroach on larger metropolitan areas.
