Creating vaccines against some of the most dangerous bacterial pathogens might be as simple as giving them a cold — or at least a cold gene.
By replacing a single gene in pathogenic bacteria with a gene from bacteria that live in the arctic, scientists report that they have developed a modifi... Read More
Ear infections: almost every kid has suffered through them at least once, making otitis media the most common reason for pediatric visits and new antibiotic prescriptions in children. But those little bottles of sweet pink antibiotics don’t always clear up ear infections. Bacteria often form m... Read More
Most people fail to properly prevent the spread of contagious and infectious germs when coughing and sneezing, according to a study by medical students in New Zealand.
For the study, the students secretly watched hundreds of people cough or sneeze at a train station, a shopping mall and a hos... Read More
HIV research is undergoing a renaissance that could lead to new ways to develop vaccines against the AIDS virus and other viral diseases.
In the latest development, U.S. government scientists say they have discovered three powerful antibodies, the strongest of which neutralizes 91% of HIV str... Read More
Dr. Alexander Khoruts had run out of options.
In 2008, Dr. Khoruts, a gastroenterologist at the University of Minnesota, took on a patient suffering from a vicious gut infection of Clostridium difficile. She was crippled by constant diarrhea, which had left her in a wheelchair wearing diaper... Read More
Animal lovers may be accidentally killing one of the UK's best-loved mammals with their kindness, scientists believe. Red squirrels may be picking up potentially deadly bacteria from the hands and skin of people putting out food for them.
The wildlife specialists are far from proving a defin... Read More
Nearly 1 out of every 25 restaurant-associated foodborne outbreaks with identified food sources between 1998 and 2008 can be traced back to contaminated salsa or guacamole, more than double the rate during the previous decade, according to research released by the Centers for Disease Control and...

A team of scientists from the Institute for Research in Immunology and Cancer (IRIC) of the University of Montreal have identified vitamin B3 as a potential antifungal treatment. Led by IRIC Principal Investigators Martine Raymond, Alain Verreault and Pierre Thibault, in collaboration with Alaka... Read More
The ubiquitous virus linked to cervical, vaginal and throat cancers may also raise the risk of developing squamous cell carcinoma, the second most common form of skin cancer, a new study suggests.
The risk from human papillomavirus (HPV) seen in a new study was even higher if people are takin... Read More
New federal rules designed to reduce Salmonella Enteritidis (SE) contamination in eggs from large-scale producers take effect today, with the Food and Drug Administration (FDA) predicting that they will prevent up to 79,000 illnesses per year.
The rules, several years in preparation, require... Read More

Researchers have discovered a monoclonal antibody that is effective against "Avian" H5N1, seasonal H1N1 and the 2009 "Swine" H1N1 influenza. Scientists at Sea Lane Biotechnologies, LLC, in collaboration with Mt. Sinai School of Medicine, St. Jude Research Hospital and the Scripps Research Instit... Read More
Scientists have discovered that 22 species of passerines--songbirds and perching birds--in the contiguous U.S. are carriers of low-pathogenicity avian influenza. Pathogenicity is the ability of a germ to produce an infectious disease in an organism.
The researchers report their results in the... Read More
Research into the human microbiome is expected to trigger development of new diagnostic tests that will be offered by clinical pathology laboratories. That’s because the organisms that live on us and in us are as unique to individuals as their DNA, and scientists believe these microbes may be ju... Read More
Suzanne Lee can conjure clothing out of thin air. No, wait, that’s not entirely accurate. She’ll need at least a couple of bathtubs, some yeast, a pinch of bacteria, and several cups of sweetened green tea. Lee, who is a senior research fellow at the School of Fashion & Textiles at Central Saint... Read More
New strains of the bacteria that cause Lyme disease have been found in B.C., according to a recently published study on ticks collected from birds across Canada.
Researchers found the genetic makeup of three bacteria differed from previously known strains.
"In the ticks that we got from th... Read More
After 86 episodes of TWiV, I am still loving every minute of the podcast and I am constantly impressed with how much I learn. For example, I have been mentoring an undergraduate student in the lab and we have had a rough two week stret... Read More
