Bloodstream infections caused by tubes inserted into major blood vessels of intensive care patients showed a big drop from 2001 to 2009, government researchers said on Tuesday.
But the researchers also reported unacceptably high rates of the same type of infections in other hospital wards and... Read More
A pathway whereby bacteria communicate with each other has been discovered by researchers at the Hebrew University of Jerusalem. The discovery has important implications for efforts to cope with the spread of harmful bacteria in the body.
Bacteria are known to communicate in nature primarily ... Read More
Researchers from the National Institute of Standards and Technology (NIST) and the Weill Cornell Medical College have designed artificial "protocells" that can lure, entrap and inactivate a class of deadly human viruses—think decoys with teeth. The technique offers a new research tool that can b... Read More
If the laboratory is not able to identify group-B streptococci (GBS) by the Lancefield grouping procedure, there are other microbiologic tests that can be used to identify GBS. This picture shows one of these tests. It is called the CAMP test. CAMP is an acronym for the authors of this test (Chr... Read More
US health officials are warning air travelers about possible exposure to measles, after a woman infected with the highly communicable disease traveled in Britain and several US states.
The 27-year-old first traveled from Britain to Washington Dulles International Airport in Virginia, just out... Read More
Good news from the CDC: the number of central-line bloodstream infections in intensive-care patients dropped 58% to an estimated 18,000 in 2009 from 43,000 in 2001.
Why is that important? Because someday you, too, may end up in the ICU with a tube in a chest or neck vein, and you really don’t... Read More
Researchers at The Forsyth Institute have made a significant discovery about the nature of childhood dental disease. The scientific studies led by Anne Tanner, BDS, Ph.D., identified a new pathogen connected to severe early childhood caries (cavities). This bacterium, Scardovia wiggsiae, was pre... Read More
A recent boom in research on the gut microbiota is revealing that these communities are even more integral to human health than previously thought. And now a study published in mBio yesterday draws more links between gut microbes and metabolism. Colonizing the guts of germ-free mice with bacteri... Read More
Writing in the journal Nature Communications, the team have created a microscope which shatters the record for the smallest object the eye can see, beating the diffraction limit of light.
Previously, the standard optical microscope can only see items around one micrometre -- 0.001 millimetres... Read More
This is a debut that I hope will grow into a larger and more useful database: Any contributions are welcome. Read More
Bacterial propulsion systems are intriguing for nanotechnology researchers because nature has already solved most of the problems that they are still struggling with in designing molecular motors and other self-sustained nanoscale actuating systems. Indeed, it has turned out to be very challengi... Read More
New findings by a University of Maryland-led team of scientists indicate that a genetically engineered fungus carrying genes for a human anti-malarial antibody or a scorpion anti-malarial toxin could be a highly effective, specific and environmentally friendly tool for combating malaria, at a ti...

Between 19 January and 17 February 2011, 10 cases of measles (eight laboratory-confirmed and two probable) were reported in Oslo with the majority of cases in a mainly unvaccinated immigrant community. Of these, two cases were identified outside the immigrant community, in Norwegian children. Read More
Half of men in the general population may be infected with human papillomavirus or HPV, the human wart virus that causes cervical and other cancers, strengthening the case for vaccinating boys against HPV, U.S. researchers said on Monday.
U.S. vaccine advisers have been weighing whether boys ... Read More
Multiple viruses have been linked to ME/CFS suggesting that multiple pathogens cause the same disease or several diseases with core signs and symptoms. Or if you are on Team XMRV /MuLV - a retrovirus could be the mastermind. No matter how you slice it in science, questions beget theories which... Read More
This thin-section transmission electron micrograph (TEM) revealed the ultrastructural appearance of a single virus particle, or “virion”, of measles virus. The measles virus is a paramyxovirus, of the genus Morbillivirus. It is 100-200 nm in diameter, with a core of single-stranded RNA, and is c... Read More
This negatively-stained transmission electron micrograph (TEM) revealed the presence of Rubella virus virions, as they were in the process of budding from the host cell surface to be freed into the host’s system, thereby, producing an enveloped virus particle, which means that after budding, the...

Researchers identified a monoclonal antibody (MAB) that neutralizes West Nile virus (WNV) by binding and crosslinking viral surface proteins that are needed to infect host cells. "The antibody crosslinking causes the virus to become rigid, and this rigidity prevents conformational changes and lo... Read More
Although, in the majority of cases, the localized presence of Neisseria meningitidis in the throat has no consequence, it can sometimes lead to meningitis or septicaemia. The seriousness of these two infections is driving researchers from around the world to improve their understanding of the mo... Read More
