A team of scientists is all set to investigate whether viruses that have adapted to higher temperatures can jump species more easily, which could shed light on the characteristics of host-switching viruses such as the avian flu or H1N1.
The team, which consists of a computational biophysicist... Read More
The U.S. Food and Drug Administration (FDA) recently announced their approval for a high dosage flu vaccine. Fluzone High-Dose is a vaccine made for adults ages 65 yrs and older to protect against influenza virus A and B.
This age group is the most susceptible to complications from seasonal i... Read More
Jamie Lee Curtis may have made probiotics a household word as a spokeswoman for Activia yogurt, but the idea of regulating the digestive tract by adding good bacteria to the intestinal mix is nothing new.
In 1907, Russian-born scientist Eli Metchnikoff suggested that better health could be ha... Read More
Injury issues aside (see John Mcdonalds HUS story), the problem with tenderized beef is that it internalizes bacteria from the surface of intact cuts of beef, thereby reducing the likelihood that cooking will serve as an effective kill step. The recent (ongoing???) outbreak of E. coli O157:H7 l... Read More
China has started treating severely infected swine flu patients with blood plasma donated by survivors - a therapy not yet proven to work but one that has shown potential to save lives.
In many parts of China, government-run blood collection stations have been harvesting plasma from people wh... Read More
Although H1N1 has proven less deadly than originally anticipated, it has taken a serious toll on American Indians.
According to a recent report released by the Centers for Disease Control and Prevention, the mortality rate from the virus is four times higher among American Indians and Alaska ... Read More
The Earth is estimated to have about a nonillion (1030) microbes in, on, around, and under it, comprised of an unknown but very large number of distinct species. Despite the widespread availability of microbial genome data -- close to 2,000 microbes have been and are being decoded to date -- a v... Read More
(ed's note - check about 2/3 of the way through the article for a bit about the role bacteria play in snow formation)
Snowstorms tend to cripple cities with residents poorly practiced in the use of shovels, plows and tire chains. At the same time, such places seem to revel more heartily in th... Read More
Hong Kong's Centre for Health Protection (CHP) of the Department of Health is investigating a case of influenza A (H9N2) infection - a mild form of avian influenza - involving a 35-month-old girl.
A spokesman for CHP said today (December 23) the girl, living in Sha Tin, developed symptoms of ... Read More
About 300 survivors of a deadly outbreak of SARS in China in 2003 are now suffering from serious after-effects, possibly due to aggressive hormone treatment to save their lives, the Beijing News said on Friday. Read More
How do one-celled parasites move from the salivary gland of a mosquito through a person's skin into red blood cells? What molecular mechanisms form the basis for this very important movement of the protozoa? A team of researchers headed by Dr. Friedrich Frischknecht, head of a research group at ... Read More
When the heads of the Centers for Disease Control and Prevention, the Food and Drug Administration, and the National Institute of Allergy and Infectious Diseases came to see us last week, they had some good news. The second wave of the H1N1 virus (known to the rest of us as swine flu) had reache... Read More
A common type of bacteria could help curtail the spread of mosquito-borne diseases by making the pests more resistant to infection, according to a study published Thursday in the US journal Cell.
The research built on an earlier study that found the lives of one type of disease-carrying mosqu... Read More
Scientists from Binghamton University and State University of New York have discovered key regulators required for the formation of biofilms - communities of bacteria in self-produced slime - which could lead to new ways for treating chronic infections.
These biofilms may be found almost anyw... Read More
In the antibiotic-resistance world, MRSA gets most of the press. Sometimes, C. difficile works its way into a headline or two. But here's a reminder that other bacteria are growing stronger as well.
A study published online Wednesday in the journal Infection Control and Hospital Epidemiology ... Read More
Everyone needs a little bit of "me time" now and again, but too much solitude can make us lonely and irritable and put us in a not-quite-right state of mind. According to recent medical research reported by Discovery News, similar stir-craziness has been observed in bacteria that are sequestered... Read More
Aker University Hospital is a dingy place to heal. The floors are streaked and scratched. A light layer of dust coats the blood pressure monitors. A faint stench of urine and bleach wafts from a pile of soiled bedsheets dropped in a corner.
Look closer, however, at a microscopic level, and th... Read More
An international group of researchers has sequenced and characterized the genome of a cavity-causing bacterial species called Bifidobacterium dentium, identifying key features that have helped the bug become a tooth decay specialist.
The team, which includes collaborators from Europe, the UK,... Read More
A new study reports a surge in drug-resistant strains of a dangerous type of bacteria in US hospitals: Acinetobacter strikes patients in Intensive Care Units (ICUs) and others and often causes severe pneumonias or bloodstream infection, some of which are now resistant to imipenem, an antibiotic ...
