Just in time for flu season, a new Michigan State University study of “the mother of all pandemics” could offer insight into infection control measures for the flu and other epidemic diseases.
Siddharth Chandra, director of MSU’s Asian Studies Center and professor in MSU’s James Madison Colle... Read More
Intracellular pathogens face many daunting problems, among them how to obtain enough energy and nutrients for active growth while, preferably, keeping the host cell alive for as long as possible. This issue is especially acute for pathogens that grow at a fast rate and reach large numbers. When ... Read More
I have received many questions about whether immunizing with Reston virus could protect against infection with Ebola virus. Usually the question comes together with the statement ‘because Reston virus does not cause disease in humans’. I can think of two reasons why a Reston virus vaccine is not... Read More
Ebola is transmitted from person to person through direct contact with the body or with body fluids of an infected person. Ebola virus is NOT a respiratory virus and is NOT transmitted through the air. It is not a gastrointestinal virus either, so it is NOT generally transmitted via water or foo... Read More
On July 20 a man who was ill flew on commercial planes from the heart of the Ebola epidemic in Liberia to Lagos, Nigeria's largest city. That man became Nigeria's first Ebola case—the index patient. In a matter of weeks some 19 people across two states were diagnosed with the disease (with one a... Read More
German an French Scientists found out: Soil bacteria contribute to the taste and smell of white truffles.
Truffles, along with caviar, are among the most expensive foods in the world. Because they grow underground, people use trained dogs or pigs to find them. But the distinctive smell of tru... Read More

Us government ban on research into enhanced pathogens also affects flu surveillance and vaccine work.
US researchers are worried that a temporary government ban on 'gain-of-function' experiments that boost the infectious properties of dangerous viruses may also cover less-extreme forms of the... Read More
Over the past eight years, step-by-step, researchers have established a basic understanding of the CRISPR defenses against foreign DNA so widely used by both bacteria and archaea. We related the early story on STC in 2008 and commented on six additional questions in 2011. Still, questions remain... Read More
These days, antibiotics are no silver bullet. In fact, if you get them in the hospital, you may end up with an additional infection. Like the bug Clostridium difficile, or C. diff — which infects more than 300,000 Americans a year and kills some 14,000. C. diff flourishes in the post-antibiotic,... Read More
This Week in Virology, the podcast about viruses, celebrated its 300th episode on Tuesday, August 26, 2014 with a live recording at the Washington, DC headquarters of the American Society for Microbiology. This special episode features the TWiV hosts Vincent Racaniello, Dickson Despommier, Al... Read More
Dear water-based life forms:
It is 24 degrees in Overland Park, Kansas and I am looking at a slide labeled "Giardia lamblia", part of a museum exhibit on water and human (over) use of water.
I see a greenish lump. I don't kno... Read More
The Ebola virus disease epidemic already devastating swaths of West Africa will likely get far worse in the coming weeks and months unless international commitments are significantly and immediately increased, new research led by Yale researchers predicts.
The findings are published in the Oc... Read More
Viruses cannot multiply without cellular machinery. Although extensive research into how pathogens invade cells has been conducted for a number of viruses, we do not fully understand how the shell of a virus is cracked open during the onset of infection thus releasing the viral genome. An ETH Zu... Read More
Just like those of humans, insect guts are full of microbes, and the microbiota can influence the insect's ability to transmit diseases. A new study reports that a bacterium isolated from the gut of an Aedes mosquito can reduce infection of mosquitoes by malaria parasites and dengue virus. The b... Read More
A new study is helping to rewrite Ebola’s family history.
The research shows that filoviruses — a family to which Ebola and its similarly lethal relative, Marburg, belong — are at least 16-23 million years old.
Filoviruses likely existed in the Miocene Epoch, and at that time, the evolutio... Read More
