Dengue Fever Makes Inroads into the U.S.

The mosquito-borne infection is cropping up in Florida, but mysteriously not in similar regions in the nation.

Most Americans lose little sleep over dengue fever. The mosquito-borne infection is a leading killer in the tropics and subtropics, but it’s been a long-held belief that ubiquitous a... Read More

2 health care workers exposed to MERS patient had flu-like symptoms

Two health care workers went to the emergency room with flu-like symptoms after coming into contact with a patient confirmed to have Middle East Respiratory Syndrome, or MERS, officials said Tuesday.

The Florida patient represents the second confirmed case of MERS brought into the United Stat... Read More

Cancer Survivor Saved by Measles Virus Raises Funds for Expanded Trial

After battling blood cancer for 10 years, Stacy Erholtz has no signs of the disease, thanks to an experimental treatment that used an engineered version of the measles virus.

Now, a year after finishing her treatment, the 50-year-old mother of three is transitioning from patient to advocate, ... Read More

Microbiology and Peep Science at Easter?

Easter in the United States has become a holiday pretty much about high fructose corn syrup. To that end, here is a description of "Peep Science," using those sugary creatures that inhabit this time of year. In addition is a video that links "Peep Science" and microbiology! Read More

Antimicrobial Properties

The emergence of antimicrobial resistance, coupled with the availability of fewer antifungal agents with fungicidal actions, prompted this present study to characterize Candida species in our environment and determine the effectiveness of virgin coconut oil as an antifungal agent on these specie...

Why Scientists Are Trying Viruses To Beat Back Bacteria

Not all viruses are bad for us. Some of them might even help up us fight off bacterial infections someday.

Naturally occurring viruses called bacteriophages attack specific types of bacteria. So researchers at the University of Leicester decided to try and take advantage of phages' bacteria-d... Read More

World Polio Day

As a virologist who has worked on poliovirus since 1979, I would be remiss if I did not note that today, 24 October, is World Polio Day. World Polio Day was established by Rotary International over a decade ago to commemorate the birth of Jonas Salk, who led the first team to develop a vaccine a... Read More

Like cling wrap, new biomaterial can coat tricky burn wounds and block out infection

Wrapping wound dressings around fingers and toes can be tricky, but for burn victims, guarding them against infection is critical. Today, scientists are reporting the development of novel, ultrathin coatings called nanosheets that can cling to the body’s most difficult-to-protect contours and ke... Read More

On Finding Jewels in the Junk

In prokaryotes, it only takes a small jazz band to get the music grooving: piano and a rhythm section suffice. The promoter region of a gene is a tiny stage on which RNA polymerase (p) and few transcription factors (dr, b) improvise on a tune, i.e. they initiate or skip transcription. By contras... Read More

Salmonella Infections Fall, But Foodborne Illness Rates Unchanged

Infection from salmonella bacteria, the most common form of food poisoning in the U.S., declined last year but the overall rate of foodborne illness is holding stubbornly steady despite new measures intended to curb it, according to data released Thursday by the federal Centers for Disease Contr...

Plasmas attack bacterial cells on several levels

As they destroy bacteria very efficiently, plasmas constitute an alternative to chemical disinfectants and potentially to antibiotics, as well. How they achieve this effect has been investigated by biologists, plasma physicists and chemists at the Ruhr-Universität (RUB). Cold atmospheric-pressur... Read More

Scientists think mysterious virus could be a signal of a weak immune system

Genomic analysis of transplant patients finds an opportunistic microorganism whose elevated presence could be used an indicator in treatment.

More than 260,000 Americans are alive today thanks to transplant operations that have replaced their failing kidneys, hearts, lungs or livers with hea... Read More

Ancient buried treasure found in daisy seeds

By tracing the evolutionary origin of a drug-like protein ring found in sunflowers, Australian and US scientists have discovered a diverse, 18-million-year-old group of buried proteins in daisy seeds.

Researchers at The University of Western Australia, working with academics from The Universi... Read More

Giving Chickens Bacteria ... To Keep Them Antibiotic-Free

You know those foods and pills that promise to supply your body with "good bacteria?"

They may or may not make you healthier, but some of these "probiotics" do, in fact, appear to be effective in chickens. Poultry companies are turning to probiotics as an alternative to antibiotics, which hav... Read More

Early antibiotic exposure leads to lifelong metabolic disturbances in mice

Antibiotic exposure during a critical window of early development disrupts the bacterial landscape of the gut, home to trillions of diverse microbes, and permanently reprograms the body’s metabolism, setting up a predisposition to obesity, according to a new study. Moreover, the research shows t... Read More

EU worries over pig virus prompt new blood import rules

The EU Commission has agreed new rules to limit the spread of a deadly swine disease that has killed millions of piglets in the US.

Porcine Epidemic Diarrhoea virus (PEDv) has wiped out around 10% of the American herd in a year.

While the EU rejected an outright ban on live pig imports, it... Read More

Penn Research Develops ‘Onion’ Vesicles for Drug Delivery

One of the defining features of cells is their membranes. Each cell’s repository of DNA and protein-making machinery must be kept stable and secure from invaders and toxins. Scientists have attempted to replicate these properties, but, despite decades of research, even the most basic membrane st... Read More

Structural insights into inner workings of viral nanomachine

Researchers are using new nanoscale imaging approaches to shed light on the dynamic activities of rotaviruses, important pathogens that cause life-threatening diarrhea in young children. Once a rotavirus enters a host cell, it sheds its outermost protein layer, leaving behind a double-layered pa... Read More
