National Institutes of Health (NIH) researchers have developed a model of infection in rhesus macaques that will help scientists around the world better understand how an emerging coronavirus, first identified in September 2012, affects people. The virus has so far infected at least 17 people in... Read More
Deep in the bowels of our, well, bowels, lurk trillions of microscopic bacteria. But don't be fooled by the big bad "B" word, intractably tied to infections and disease. In fact, these bitty bugs do us a world of good.
"There's a certain 'ick' factor associated with gut bacteria," said Lita P... Read More
Federal land managers have rejected an application by a Colorado company to use bacteria to produce methane from northeast Wyoming coal beds.
Luca Technologies Inc. wants to use a process called methane farming in which water and chemicals are injected into a coal seam, activating microbes th... Read More
Researchers have found a strain of bacteria that can infect mosquitoes and make them resistant to the malaria parasite. The study, in the journal Science, showed the parasite struggled to survive in infected mosquitoes. Malaria is spread between people by the insects so it is hoped that giving m... Read More
French health officials said Friday they are investigating three suspected cases of a deadly new respiratory virus related to SARS, in people who had close contact in the hospital with France's only confirmed case.
Beatrice Degrugillers, a spokeswoman for the regional health agency in France'... Read More
Observing microbes in nature is a challenge. Compared to what goes on in the lab, there is not much one can do with them out there. So, instead of bringing the bacteria to the lab, why not bring the lab to the bacteria? Imagine being able to capture the expression of genes of a community of micr... 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
In this blog entry, I discuss the perennial problem for educators: helping students find study strategies that help them reach their educational goals. I have found that student-generated study material is most helpful...and is sometimes quite artistic! Read More
When a phage invades a host’s premises, it delivers only its genome and perhaps a few specialized proteins needed immediately upon arrival. Its plan is simply to supervise production. The host is relied on to provide not only the raw materials and energy, but also the production equipment needed... Read More
Shingles vaccine is associated with reduction in both postherpetic neuralgia and herpes zoster, but uptake in the US is low. A vaccine to prevent shingles may reduce by half the occurrence of this painful skin and nerve infection in older people (aged over 65 years) and may also reduce the rate ... Read More
A key building block in the Schmallenberg virus could be targeted by anti-viral drugs, according to a new study led from the University of Leeds. The disease, which causes birth defects and stillbirths in sheep, goats and cattle, was first discovered in Germany in late 2011 and has already sprea... Read More
A study at the Virginia-Maryland Regional College of Veterinary Medicine has identified a chicken-killing virus as a promising treatment for prostate cancer in humans.
Researchers have discovered that a genetically engineered Newcastle disease virus, which harms chickens but not humans, kills... Read More
Trichomonas vaginalis is a protozoan parasite of the urogenital tract in men and women and causes a sexually transmitted disease, trichomoniasis, in about half of infected women. Infections are associated with pelvic inflammatory disease, adverse pregnancy outcomes, infertility, an increased inc... Read More
Thousands of women suffer from overactive bladder (OAB) or the sudden need to urinate, yet many don’t get relief from medication. Researchers at Loyola University Health System believe certain bacteria may be to blame.
Loyola has launched a clinical trial to determine if the bacteria present ... Read More
A team of researchers based at Johns Hopkins has decoded a system that makes certain types of immune cells impervious to HIV infection. The system's two vital components are high levels of a molecule that becomes embedded in viral DNA like a code written in invisible ink, and an enzyme that, whe... Read More
El podcast del microbio Nº 378 summarize an article published in Nature communications by Ribeiro-Viana R et al. on the use of Virus-like glycodendrinanoparticles to block viral infection. El podcast del microbio Nº 3... Read More
A new bird flu virus that has killed 13 people in China is still evolving, making it hard for scientists to predict how dangerous it might become.
Influenza experts say the H7N9 strain is probably still swapping genes with other strains, seeking to select ones that might make it fitter.
If... Read More
Researchers at NIAID have devised a method for delivering tumor cell-killing enzymes in a way that protects the enzyme until it can do its work inside the cell. In their study in mBio this week, researchers assembled microscopic protein packages that can deliver an enzyme called PEIII to the ins... Read More
Hilary Koprowski, a pioneering virologist who was credited with developing the first successful oral vaccination for polio, died April 11 at his home in Wynnewood, Pa. He was 96. Read More
A new study in the Netherlands has found a deep-sea microbe living in high-temperature hydro-thermal vents can thrive on chlorate and perchlorate anions. Perchlorate, an ingredient in rocket fuel and fireworks, is toxic to most organisms.
The researchers, led by Martin Liebensteiner of Wageni... Read More
