When just floating peacefully in the water with their brood mates, the Culex mosquito larvae in the image above does not look very frightening. But in their adult form, they are the prime vector for spreading West Nile virus — a sometimes mild, sometimes fatal disease.
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.
If you're anything like me, your day doesn't start until you've sloughed away your grogginess with a scalding hot shower. That perfectly-heated water can clear stuffed sinuses, relax the muscles, and make pretty much anyone feel squeaky clean. However, a cold shower can do even more for you if you can stand the low temperatures.
Despite mounting scientific evidence that viruses can cause changes in learning and memory, the reasons have remained elusive.
Future mothers hoping to use donated semen might want to think twice before using any samples from the Miami-Dade Country area of Florida. The Centers for Disease Control and Prevention (CDC) is warning that sperm from as far back as June 2016 may be infected with the Zika virus. Damn those mosquitoes.
It's that time of year again. The month after we exchange gifts, most of us tend to exchange germs. Cold and flu season always seems to creep up on us, often leaving us ill-prepared to deal with the ailments.
All fields of study have their own language. For people interested in learning about microbes, the language can sometimes be downright difficult — but it doesn't need to be. From antibiotics to xerophiles, we have you covered in an easy-to-understand glossary.
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?
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 seatmate's viral or bacterial effusions will circulate throughout the plane and infect everyone on board.
A new study shows the Zika virus is present in saliva — but it may not be enough to make you sick. The Centers for Disease Control and Prevention notes there is "no evidence that Zika can be transmitted through saliva during deep kissing." Given the results of research published in the journal, Nature Communications," the agency may need to revise its guidance.
Respiratory Syncytial Virus (RSV) is the most commonly occurring lower respiratory tract viral infection in young children and usually isn't serious, but in premature infants and babies under six months old, the infection can be severe, and even fatal.
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.
Usually, we think of vaccines as preventative, a shot we get to prevent the flu or some childhood disease like measles or mumps. But there are vaccines for other purposes, such as the ones studied by researchers from the Netherlands.
Ecosystem changes caused by agricultural choices in Brazil are creating a dangerous microbe mix in exploding populations of vampire bats and feral pigs.
The mention of Zika can strike fear in the hearts of pregnant women. With infections increasing around the world, including in the US, researchers are fighting the clock to figure out how the virus can have such horrific effects in some people.
There are rules that cooking in general always follows: cakes should be fluffy. Steaks should be heavily seasoned, and nowhere near a bottle of steak sauce. Every stock should start with aromatics (onions, carrots, & celery). And, until very recently, meringues should always be made with egg whites.
With the nation facing a shortage of ventilators for COVID-19 patients and no apparent ramp-up in the production of new ones, engineers, medical resistents, and do-it-yourselfers are sharing plans for homemade versions.
The World Health Organization has declared the new coronavirus a pandemic, and the Centers for Disease Control and Prevention recommends video visits with a healthcare professional to reduce the risk of being exposed to the coronavirus that causes COVID-19. If you are experiencing mild flu-like symptoms, virtual doctor visits may also prevent you from endangering others.
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.
While Lyme disease can be disabling, the wrong treatment for the infection can be fatal.
The possibility of severe tickborne illness is increasing as an aggressive tick from the American southeast moves up the Atlantic Coast.
The theme for 2017's World Malaria Day, which is today, April 25, is "End Malaria for Good." For many Americans, this might seem like an odd plea. Especially since Malaria is seemingly an obsolete problem here. However, on World Malaria Day, it's important to remember the danger of malaria is still very much present in the US. And around the world, the disease is at the epicenter of a global crisis.
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.
Tremendous strides have been made in the treatment and outlook for patients infected with HIV, the human immunodeficiency virus. Treatment with a combination of antiretroviral drugs can keep patients with HIV alive for decades, without symptoms of the infection. The trouble is, if HIV-infected people stop taking their medications, the virus takes over in full force again—because the virus hides out quietly in cells of the immune system, kept in check, but not killed by the treatment.
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.
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.
As fun as it is to see Fido's face light up when you feed him table scraps, American dogs are getting fat. The good news is that research is homing in on nutritional strategies to boost canine capabilities to maintain a healthy weight.
A recent pathogen outbreak in Illinois is just one of many outbreaks of an underappreciated, but serious, viral infection passed from rodents to humans. These hantaviruses have been cropping up more frequently in the last decade or so, giving us more reason to clean out our dusty attics, basements, and garages.
Findings from a mouse study suggest that the Zika virus infection may have serious reproductive consequences for men.
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.
Uh-oh: you wake up one morning with the telltale signs that you are coming down with something. Your throat is sore, you can barely breathe out of your nose, and you have a nagging cough.
The landscape of podcasting has exploded in recent years, with everyone from dedicated longtime podcasters reaching the mainstream spotlight, to traditional media personalities moving from TV, radio, and newspapers to grab a slice of the listening pie. The good news is that the barrier to entry is relatively low, so even if you're not a celebrity or media luminary, you can still get your voice out there by starting a podcast.
Blowing dust and fungal spores are creating a public health problem that could be just a slice of what's to come with climate change.
Killing more than 29,000 people each year, infection with Clostridium difficile (C. diff or CDI) is the most common healthcare-associated infection in the US. In a disturbing development, new research reveals recurring cases of the infection are soaring.
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 best go-to method for reducing your risk of infection is to wash your hands. Next time you reach for the soap, here is some news you can use.
As a part of the already crowded field of diseases transmitted by ticks, you may not know the disease babesiosis, a dangerous infection caused by a parasite that infiltrates blood cells.
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?
You can get eggs and high-quality compost from backyard chickens—but you can also get Salmonella.
It won't come as a surprise to hear that your cell phone, tablet, and laptop are loaded with bacteria and other organic material. While most of these bacteria are harmless, there are good reasons to reduce the capability of your mobile devices to infect you—or other people.
