Tom talks with Vincent about viral central nervous system infections of global importance, Ebola virus, and running the fastest marathon dressed as a doctor.
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
Vincent and Dickson discuss how malaria parasites induce odors in their rodent hosts that attract mosquitoes.
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
Many different microbes can cause pneumonia, and treatment may be delayed or off target if doctors cannot tell which bug is the culprit. A novel approach—analyzing a patient's breath for key chemical compounds made by the infecting microbe—may help detect invasive aspergillosis, a fungal infecti... 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
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
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
Mineral coatings on sand particles actually encourage microbial activity in the rapid sand filters that are used to treat groundwater for drinking, according to a paper published ahead of print in Applied and Environmental Microbiology. These findings resoundingly refute, for the first time, the... 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
New results from a safety and immunogenicity study, which included a challenge phase to test efficacy, indicate that a live attenuated enterotoxigenic Escherichia coli (ETEC) vaccine candidate, given in combination with a novel adjuvant, provided significant protection against disease. This repr... 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

Is complex life rare in the cosmos? The idea that it could be rests on the observation that the existence of life like us – with large, energy hungry, complicated cells – may be contingent on a number of very specific and unlikely factors in the history of the Earth. Added together they suggest ... Read More

Researchers have made a breakthrough in understanding how a powerful antibiotic agent is made in nature. Their discovery solves a decades-old mystery, and opens up new avenues of research into thousands of similar molecules, many of which are likely to be medically useful.

I had a pink fungal contaminant on one of my plates.
When I looked at it under the microscope, I found some budding yeast. Read More
The DNA of a virus once thought confined to the cells of algae may in fact invade the biological kingdom of mice and men, according to a new study from researchers at Johns Hopkins University in Baltimore and the University of Nebraska-Lincoln.
The researchers, whose paper appeared Oct. 27 in... 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
