Despite the pointless political assassinations of vaccine workers or the police officers who guard them in a few deeply troubled areas, enough progress has been made against polio in the past year that health experts are now planning for the grand finale—its complete eradication by 2018. The off... Read More
18th International Bioinformatics Workshop on Virus Evolution and Molecular Epidemiology
VEME 2013 will be organized August 25th – August 30th, 2013 at the University of Florida in Gainesville, Florida, U.S.A.
The workshop will have the following modules:
• 'Phylogene... Read More
Hepatitis A virus (HAV) is classified as a non-enveloped Picornavirus. That may have to change, or at least be more specific.
Via electron microscopy, this team found a certain percentage of these viruses were enveloped in exosome-sized particles. Up to 4 virions were found inside these membr... Read More
Background on structural analysis of bacterial proteins, from Erec Stebbins, speaker at the 2012 Holiday Lecture "Bacteria's Deadly Design: How Earth's most prevalent life-form uses a microscopic syringe to invade and attack."
Bacteria, viruses and parasites from land animals such as cats, cows and humans are sickening and killing sea mammals. Scientists have been finding a daunting number of land-based pathogens in seals, dolphins, sharks and other ocean dwellers that wash ashore dead or dying, according to an articl... Read More
Radioactive iron may be first fossil imprint of a nearby cosmic explosion. Sediment in a deep-sea core may hold radioactive iron spewed by a distant supernova 2.2 million years ago and preserved in the fossilized remains of iron-loving bacteria. If confirmed, the iron traces would be the first b... Read More
Exposing packaged liquids, fruits and vegetables to an electrical field for just minutes might eliminate all traces of foodborne pathogens on those foods, according to a Purdue University study.
Kevin Keener, a professor of food science, looks for new ways to kill harmful bacteria, such as E.... Read More
Some facts about the toxin that was found in a letter addressed to US senator Roger Wicker. Government officials in Washington have shut down mail delivery to the US Senate after detecting ricin in a letter addressed to Mississippi senator Roger Wicker, a Republican, on 16 April. Here are some f... Read More
As much as dog owners love their children, they tend to share more of themselves, at least in terms of bacteria, with their canine cohorts rather than their kids.
That is just one finding of a new study led by the University of Colorado Boulder that looked at the types and transfer modes of m... Read More
Doctors say the discovery of a 4-year-old carrier of the H7N9 bird flu virus who shows no symptoms of the potentially lethal virus is a worrying development that could make the spread of the infection more difficult to monitor.
The Beijing Municipal Health Bureau said the boy was detected fro... Read More
There have been over 60 human infections with avian influenza virus H7N9 in China, and cases have been detected outside of Shanghai, including Beijing, Zhejiang, Henan, and Anhui Provinces. Information on the first three cases has now been published, allowing a more detailed consideration of the... Read More
"Like rolling back a rock and seeing the ecosystem change," says the lead author of a study in mBio this week. It's a classical experiment in grade school ecology, except that the ecosystem is the microbiome of the human penis. And the "rock" is the foreskin, removed in adulthood for the sake of... Read More
Pili are hair like appendages that are found on the outer membrane of bacteria. They are important for bacteria to attach to solid surfaces, are used as an apparatus in transfer of DNA from one cell to another, as well as twitching motility, and cell-cell adhesion.
In 2011 a group of scientist ... Read More
Officials in Beijing confirmed today that a 7-year-old girl is infected with H7N9 avian influenza, widening the geographic spread of the virus that's already killed 11 people.
The girl, whose parents sell live poultry, was admitted to the hospital Thursday with pneumonia and is the first case... Read More
A newly discovered rodent virus that resembles hepatitis C could give research chimps a break.
The US National Institutes of Health (NIH) is expected to make a decision imminently on how many of its 360 research chimps should be retired on the grounds that most studies can be done in other an... Read More
Scientists at The Scripps Research Institute (TSRI) have made a counterintuitive finding that may lead to new ways to clear persistent infection that is the hallmark of such diseases as AIDS, hepatitis B and hepatitis C.
The study, reported in the April 12, 2013 issue of the journal Science, ... Read More
The cholera strain that transferred to Haiti in 2010 has multiple toxin gene mutations that may account for the severity of disease and is evolving to be more like an 1800s version of cholera, reports a new Northwestern Medicine study.
The strain, "altered El Tor," which emerged around 2000, ... Read More
Newcastle University scientists have revealed the mechanism that causes a slime to form, making bacteria hard to shift and resistant to antibiotics.
When under threat, some bacteria can shield themselves in a slimy protective layer, known as a biofilm. It is made up of communities of bacteria h... Read More
Circumcision drastically alters the microbiome of the penis, changes that could explain why circumcision offers protection against HIV and other viral infections. In a study to be published on April 16 in mBio®, the online open-access journal of the American Society for Microbiology, researchers... Read More
