Viruses have historically been classified into one of two types – those with an outer lipid-containing envelope and those without an envelope. For the first time, researchers at the University of North Carolina have discovered that hepatitis A virus, a common cause of enterically-transmitted hep... Read More
THE WORLD witnessed only 223 polio cases last year, the lowest level in history and an impressive advance from the hundreds of thousands of children afflicted as recently as the 1980s. However, the eradication quest is not over, and the next steps look difficult. The Global Polio Eradication Ini... Read More
Seeing the mosquito-transmitted chikungunya virus pathogen at very high resolution while it’s bound to antibodies could lead to vaccines for the disease. The infection causes symptoms similar to dengue fever, followed by a prolonged disease that affects the joints and causes severe arthritis. In... Read More
A new study which was performed jointly at Umeå university and the University of Washington in Seattle, USA, discovered that bacteria can degrade the cell membrane of bacterial competitors with enzymes that do not harm their own membrane. This exciting finding opens the way for the development o... Read More
China said it was mobilizing resources nationwide to combat a new strain of deadly bird flu that has killed four people, as Japan and Hong Kong stepped up vigilance against the virus and Vietnam banned imports of Chinese poultry.
The H7N9 bird flu strain does not appear to be transmitted fro... Read More
Two former Canadian Food Inspection Agency researchers face charges for trying to take 17 vials of pathogens out of the country.
Klaus Nielsen, a world-leading researcher in brucella infection, and fellow researcher Wei Ling Yu have been charged with breach of trust by a public officer after ... Read More
Once upon a time, not too terribly long ago, getting the chicken pox was practically a rite of passage for kids.
But now, nearly 20 years after approval of a vaccine for the varicella virus, which causes the itchy illness, chicken pox is a rarity. A new study conducted by researchers at Kaise... Read More
Parasites pose a problem for the semantically-oriented microbiologist. There is no question that unicellular parasites such as Giardia, Plasmodium, or Toxoplasma are microbes, thus we can appropriate them with impunity. But what about parasitic worms? They are clearly not microscopic* and are ta... Read More
What is the influenza A(H7N9) virus?
Influenza A H7 viruses are a group of influenza viruses that normally circulate among birds. The influenza A(H7N9) virus is one subgroup among the larger group of H7 viruses. Although some H7 viruses (H7N2, H7N3 and H7N7) have occasionally been found to in... Read More
On 3 April 2013, the China Health and Family Planning Commission notified WHO of an additional four cases of human infection with influenza A(H7N9). The four patients are from Jiangsu province in eastern China. There is no link between the cases.
The patients include a 45-year-old woman with ... Read More
University of British Columbia researchers have discovered two new symbionts living in the gut of termites, and taken the unusual step of naming them after fictional monsters created by American horror author HP Lovecraft.
The single-cell protists, Cthulhu macrofasciculumque and Cthylla micro... Read More
Scientist at the Rensselaer Center for Biotechnology and Interdisciplinary Studies and the Rensselaer Nanoscale Science and Engineering Center for the Directed Assembly of Nanostructures have created a coating that can selectively kill the bacteria Listeria, a causative agent of food borne illne...

Glowing bacteria inside squids use light and chemical signals to control circadian-like rhythms in the animals, according to a study to be published on April 2 in mBio®, the online open-access journal of the American Society for Microbiology. The Hawaiian bobtail squid, Euprymna scolopes, houses... Read More
Call it hollow-hearted. Researchers have built a mimic of the outer capsule of the foot-and-mouth disease virus. Inside, where the virus' genetic material normally lives, is empty. Such synthetic virus-like particles could go into a foot-and-mouth vaccine that's cheaper to make because it doesn'... Read More
Biology and nanotechnology are moving ever closer together. Ars recently wrote about the use of nanoparticles to aid delivery of stem cells in cardiac therapy. Now, Swiss researchers have developed nanoparticles that can detect, and one day could combat, viruses.
When viruses enter the human ... Read More
Using the same strategy that a common virus employs to evade the human immune system, researchers at Wake Forest Baptist Medical Center's Institute for Regenerative Medicine have modified adult stem cells to increase their survival -- with the goal of giving the cells time to exert their natural...

The recent news about a baby in Mississippi and 14 French adults said to have been "cured" of HIV infection has fueled excitement that the end of HIV/AIDS could be within sight. Both situations raise more questions than they currently answer.
Although no one can say we now have "the" cure for... Read More
An alternative treatment for antibiotic-resistant infections that are raising concern nationwide already exists. But there's a big problem. The treatment is not approved for use in the United States.
And it could be a decade or more for the treatment, long used in Russia, former Soviet nation... Read More
The squid has fascinated microbiologists for years because of its harmonious relationship with just one bacteria -- Vibrio fischeri. The bacteria does not express light when it is freely roaming in the ocean, but when housed in the squid's light organ (located in its underbelly) it will work wit... Read More
Researchers at Tufts University School of Dental Medicine and the Forsyth Institute published a study today that found that a significant proportion of dental bib clips harbored bacteria from the patient, dental clinician and the environment even after the clips had undergone standard disinfecti...
