Bacteria-sniffing wand could help prevent foodborne illnesses

One in six Americans (or 48 million people) get foodborne illnesses every year. Better detection can lower that number dramatically. Bacteria detection sniffers have been studied for several years now. They are based on a wireless acoustic wave sensor platform, which is a fancy way of saying tha... Read More

Scientists Uncover Frozen Tricks Behind Ice-Seeding Bacteria

Some bacteria can harness frozen water as a weapon, using special proteins embedded in their outer membranes to help ice crystals form. Triggering frost formation, the bacteria then invades through the damaged tissues of plants. Now, scientists have observed this bacteria's ability for the first... Read More

Child 'Cured' of HIV Remains Free of Virus, Doctors Report

WEDNESDAY, Oct. 23 (HealthDay News) -- A 3-year-old Mississippi girl apparently cured of HIV infection by aggressive treatment right after her birth remains free of the virus, her doctors report. Early treatment with a combination of potent antiretroviral drugs appears to have kept the virus fro... 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

5 Things We Didn't Know About the Fungal Outbreak Last Year

Health officials are still learning from the fungal outbreak tied to tainted steroid pain injections made at the now-shuttered New England Compounding Company.

Researchers now know that most patients' immune systems didn't try to fight off the deadly fungi as it burrowed into their spinal col... Read More

Oral Bacteria Create a ‘Fingerprint’ in Your Mouth

The bacteria in the human mouth – particularly those nestled under the gums – are as powerful as a fingerprint at identifying a person’s ethnicity, new research shows.

Scientists identified a total of almost 400 different species of microbes in the mouths of 100 study participants belonging t... Read More

Obesity may increase the risk of Clostridium difficile infection

Researchers from Boston Medical Center (BMC) and Boston University School of Medicine (BUSM) have identified obesity as a possible risk factor for clostridium difficile infection (CDI). These findings, which appear online in Emerging Infectious Diseases, may contribute to improved clinical surve... Read More

Veterinary scientists track the origin of a deadly emerging pig virus in the United States

Veterinary researchers at the Virginia-Maryland Regional College of Veterinary Medicine at Virginia Tech have helped identify the origin and possible evolution of an emerging swine virus with high mortality rates that has already spread to at least 17 states.

A team of researchers led by Dr. ... Read More

Combining profiling and genomics yields novel metabolites

Researchers studied 10 different cyanobacteria to identify their secondary metabolites (compounds produced during normal cellular metabolism not directly involved in cell growth, that may play an important role in interactions outside the cell) and the genes linked to those molecules.

Underst... Read More

Annals of the Malaria War: Move over Angelina Jolie

We’re driving on a dirt road and my interpreter, one of the friendliest guys I’ve ever met, is absorbed in a conversation with a health worker in our group. Cornfields and rice paddies paint the landscape chartreuse. Donkey carts and herds of goats swerve into the plants when we rumble past. The... Read More

Single mutation gives virus new target

A mutation as minute as swapping just one amino acid can completely change the target that a virus will bind to on a victim cell — potentially shifting what kind of cell and eventually what kind of organism a virus could infect.

In a new study published online in the journal PLoS Pathogens, a... Read More

New Evidence for Role of Specific Virus Causing Type 1 Diabetes

Type 1 diabetes is a disease caused by the destruction of the insulin-producing cells in the pancreas. It is often diagnosed in childhood and requires life-long treatment with daily insulin injections. It is associated with an increased risk for long-term complications which decrease the quality...

Hitchhiking virus confirms saga of ancient human migration

A study of the full genetic code of a common human virus offers a dramatic confirmation of the "out-of-Africa" pattern of human migration, which had previously been documented by anthropologists and studies of the human genome.

The virus under study, herpes simplex virus type 1 (HSV-1), usual... Read More

Antibiotics Can't Keep Up With 'Nightmare' Superbugs

We're used to relying on antibiotics to cure bacterial infections. But there are now strains of bacteria that are resistant to even the strongest antibiotics, and are causing deadly infections. According to the CDC, "more than 2 million people in the United States every year get infected with a ... Read More

In sub-Sahara, foot and mouth disease moves over short distances

You probably remember foot and mouth disease (FMD) from the 2001 outbreak in the UK that prompted the culling of over 10 million sheep and cattle, but the disease affects livestock all over the world. It's a particular problem in Africa, where wildlife that harbor the picornavirus that causes FM... Read More

Clay Can Kill Some Antibiotic-Resistant Bacteria (video)

Researchers have found that some clay can kill powerful bacteria like e-coli and even Methicillin-resistant Staphylococcus aureus, or MRSA, which can be resistant to many antibiotics. Read More

Research offers new insight in quest for single vaccine against multiple influenza strains

A study led by St. Jude Children’s Research Hospital scientists highlights a new approach for developing a universal influenza vaccine that could protect against multiple flu strains, including deadly pandemic strains. The research appears today in the advance online edition of the scientific jo... Read More

Flu Virus Wipes Out Immune System's First Responders to Establish Infection

Revealing influenza’s truly insidious nature, Whitehead Institute scientists have discovered that the virus is able to infect its host by first killing off the cells of the immune system that are actually best equipped to neutralize the virus.

Confronted with a harmful virus, the immune syste... Read More
