The mysterious life cycle of a sheep virus that causes malignant catarrhal fever (MCF) has been discovered by Agricultural Research Service (ARS) scientists and their university collaborators -- the first step in developing a vaccine against the disease.
Microbiologist Hong Li and veterinary ... Read More
Highly dangerous Cryptococcus fungi love sugar and will consume it anywhere because it helps them reproduce. In particular, they thrive on a sugar called inositol which is abundant in the human brain and spinal cord.
To borrow inositol from a person's brain, the fungi have an expanded set of ... Read More
Tim Sampson, a graduate student at Emory University in the Microbiology and Molecular Genetics program, looks at two research papers with conflicting conclusions about the presence of endospores in very late stationary phase cultures of Mycobacterium marinum, a common model for acute Mycobacte...

Cornell researchers have created mathematical models based on interactions between species in coral reef communities that may provide insight as to why certain bacteria may help cause the reef to become bleached and ultimately destroyed.
The models and their implications for the overall healt... Read More
A description of a 95-million-year-old amber deposit—the first major discovery of its kind from the African continent—is adding new fungus, insects, spiders, nematodes, and even bacteria to an ecosystem that had been shared by dinosaurs. In addition, the amber deposit may provide fresh insights ... Read More
Norovirus has been in the news of late for sickening passengers on cruise ships, closing a middle school and postponing a college swim meet.
The virus, which causes severe gastrointestinal symptoms, has also been in my house. I most likely contracted the virus last week and have been shocked ... Read More
Scientists from the California Institute of Technology (Caltech) have provided the first-ever glimpse of the structure of a key protein -- gp120 -- found on the surface of a specific subgroup of the human immunodeficiency virus, HIV-1. In addition, they demonstrated that a particular antibody to... Read More
Great news here - the sort of thing that should lead on CNN or Fox but never will in my lifetime. However, since this advance may significantly extend my lifetime by subduing a variety of gnarly diseases, perhaps I'll eventually be proven wrong. Read More
Argentinian investigators have found flamingos and mysterious microbes living in an alkaline lagoon nestled inside a volcano in the Andes. The organisms, exposed to arsenic and poisonous gases, could shed light on how life began on Earth, and their hardiness to extreme conditions may hold the ke... Read More
Acidification of the oceans as a result of increasing levels of atmospheric carbon dioxide could have significant effects on marine ecosystems, according to Michael Maguire presenting at the Society for General Microbiology's spring meeting in Edinburgh this week. Postgraduate researcher Mr Magu... Read More
In this show, I report on four exciting stories: bacterial fingerprints, bacteria in space, fungi that swap genes, and bacteria fighting for resources.

In 2002, bearing her microscope on a microbe that lives in the gut of fish, Bonnie Bassler isolated an elusive molecule called AI-2, which showed not only that almost all bacteria can communicate -- but that they do so all the time. (Watch her 2009 TEDTalk!) The TED Blog interviewed Bassler ... Read More
Sin Hang Lee, Ph.D., a Milford Hospital pathologist has developed a test to positively diagnose Lyme disease, and to identify the bacterium that causes it within days of infection.
That is a major advance in treating a disease that is common in the region but difficult to diagnose with standa... Read More
On episode #76 of the podcast This Week in Virology, Vincent speaks with Stephen Goff about the origin of the retrovirus XMRV and its association with prostate cancer and chronic fatigue syndrome. Read More
A add-on to the picture posted here.
A living time capsule of sorts has been found buried under hundreds of feet of Antarctic ice — a colony of microbes that have been sealed off from the rest of the world for mo... Read More
Biozentrum researchers have now discovered that Escherichia coli bacteria harness a sophisticated chemosensory and signal transduction machinery that allows them to accurately control motor rotation, thereby adjusting their swimming velocity in response to changing environments. The research re... Read More
Essential oils could be a cheap and effective alternative to antibiotics and potentially used to combat drug-resistant hospital superbugs, according to research presented at the Society for General Microbiology's spring meeting in Edinburgh.
Professor Yiannis Samaras and Dr Effimia Eriotou, f... Read More
Move over, bacon. Here comes something greener.
A genetically engineered pig recently approved for limited production in Canada makes urine and feces that contain up to 65 percent less phosphorous, officials have announced.
That could be good news for lakes, rivers, and ocean deltas, where... Read More
Asian wheat may offer novel genes for shoring up the defenses of U.S. varieties against Fusarium graminearum fungi that cause Fusarium head blight (FHB) disease.
According to Agricultural Research Service (ARS) plant molecular biologist Guihua Bai, the FHB resistance found in today's U.S. wh... Read More
Dr. Rita Colwell, an expert on the prevention of waterborne infectious diseases, has been awarded the 2010 Stockholm Water Prize, widely recognized as the world's premier award for water related research or policy work.
The prize, which includes a $150,000 award and a crystal sculpture, honor... Read More
