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.
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.
As if the swollen, painful joints of rheumatoid arthritis weren't enough, the disease is the result of our immune system turning against cells of our own body. Ever since this realization, scientists have worked to find the trigger that sets the immune system off. Scientists believe that gut bacteria may have a role in initiating the abnormal immune response. Now, a team of researchers from Boston has figured out how that might occur.

On July 20, 1969, humans set foot on the moon for the first time. But some say our microbes beat us there. With the Space Age came new questions about microscopic invaders from outer space and concern about where we are leaving our microbial footprints. The questions are even more relevant today.
Whether your palate runs to domestic or imported, a piece of cheese can be a real treat for the senses. Its smell, taste, and texture are all parts of its appeal. A big part of what makes that savory wonderfulness comes from the microbes in and on the cheese. Thanks to a team of researchers dedicated to studying those microbes, we have a better understanding of their importance to cheese and us.
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.
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.
Once we recover from the respiratory infection pneumonia, our lungs are better equipped to deal with the next infection — thanks to some special cells that take up residence there.
Cancer cells do a pretty good job of flying under the radar of our immune system. They don't raise the alarm bells signaling they are a foreign invader the way viruses do. That might be something scientists can change, though.
Four million Americans misused prescription opioid painkillers in 2014. Those who do are 40 times more likely to inject heroin or other drugs than other people. Now, the Centers for Disease Control and Prevention (CDC) are blaming that misuse for a 12-fold increase in endocarditis, an infection of the heart valves.
Despite mounting scientific evidence that viruses can cause changes in learning and memory, the reasons have remained elusive.
A 6,000-year-old forest inhabitant awakens to find life in the forest around it in crisis. Plants, trees, animals, and birds are moving north to escape increasingly heated air, even as mass extinctions take place around the world. The inhabitant stirs and remembers it has lived this before and knows what to do.
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.
Antibiotics are one of our main weapons against infections. The problem is that many bacteria are becoming resistant to most of the antibiotics we use to treat them, and those 'superbugs' have created an urgent threat to our global health. A research group found a new way to hit a well known bacterial target and have developed a drug to hit it.
Young girls, especially those who live in areas where HIV is epidemic, like sub-Saharan Africa, are particularly vulnerable to becoming infected with HIV. A vaginal ring containing the antiviral agent dapivirine has been shown to decrease the chance of developing HIV-1 in adult women over 21 and now in the first step for use in adolescents, the ring has been shown to be safe and well-tolerated in that younger age group.
New research explores how the bacteria on the penis can leave men more susceptible to infection with HIV.
Forget the rise of the machines. Tardigrades are set to outlive everything — even the bots. When the last echo of a whisper in a cell phone has long dissipated into space, the water bears will still be hanging out.
Results of an early-stage clinical trial of an HIV vaccine could mean a hoped-for breakthrough in the battle against AIDS.
We might think of Zika as a mosquito-borne virus that effects developing fetuses, but, it also can be passed through sex by either a man or a woman, just like herpes and other STD viruses. New research has shown that vaginal bacteria can inhibit sexually transmitted Zika virus and Herpes Simplex Virus-2 in women.
Wherever there are people, the party is sure to follow. Well, a party of microbes, at least. That is what scientists at NASA's Jet Propulsion Laboratory have found after a 30-day microbial observation of the inflatable lunar/Mars analog habitat (IMAH).
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.
While some researchers look for drugs to treat HIV, other scientists delve deep into the virus itself for answers on how it causes infections.
Foodborne infections often occur through the contamination of equipment, food-prep tools, and unsanitary surfaces. A recent report from the Centers for Disease Control and Prevention (CDC) reminds us that breast pump parts are part of the food-delivery chain — and they can become contaminated too.
Growing evidence suggests that neurodegenerative diseases like Parkinson's may develop in part due to environmental factors, including infections that can cause inflammation in the nervous system. New research from investigators from Jude Children's Research Hospital and Thomas Jefferson University has strengthened that connection.
For a company more associated with debugging computer programs, Google's parent company, Alphabet, is making a name for itself by taking on the real thing — mosquitoes.
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.
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.
About a third of the methane released into the environment comes from the production and transport of natural gas. The gas leaks as it moves along the transport chain from gas wellheads to market.
For once there is good news — surprising news, but good news — in the fight against antibiotic-resistant organisms. A recent study found that Staphylococcus aureus bacteria is becoming more sensitive to some key drugs used to treat it.
Twelve-year old Rory Staunton took a dive for a basketball during gym class and came up with a cut on his arm. The school nurse applied a couple of band-aids, without cleaning the cut, and off he went. In approximately three days, hospital physicians told his parents there was nothing else that they could do for their son; he was dead.
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.
The next time you suffer a cut or abrasion, think twice before you reach for the Neosporin. It's time, and mom, tested — you get a cut, you wash it carefully, then apply some triple-threat antimicrobial ointment. You may or may not slap on a band-aid. We won't cover it here, but so that you know, covering the wound with a sterile dressing or band-aid is a good idea.
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.
In late June, the biggest measles outbreak to strike Minnesota since 1990 seemed to be winding down. Today, public health officials announced a new confirmed measles case in the area.
News: Bacteria Turned into Factories, Supplying Critical Enzymes to Make Cancer Drugs Cheaper & Save Endangered Yew Trees
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.
News: Vaccine Can Prevent Bad Cholesterol from Accumulating in Blood Vessels, Potentially Prevent Heart Attacks
Heart disease is the leading cause of death of men and women in the US. Over half a million Americans die from it annually. Atherosclerosis — a build up of plaque in the arteries — is a common feature of heart disease and can be caused by smoking, fats and cholesterol in the blood, diabetes, and high blood pressure.
A recent case of Powassan virus has been reported in Saratoga County and may have been the cause of the infected patient's death. It's the 24th case in New York State since 2000, and will be reported to the CDC tomorrow, the NY Department of Health told Invisiverse. The tick-borne illness has no vaccine or specific treatments and can damage the nervous system.
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.
