April 16, 2016, Barcelona, Spain: A new study presented today demonstrates the potential challenge posed to public health systems across Europe as a result of the prevalence of Hepatitis B among new refugee populations. The study was presented at The International Liver Congress™ 2016 in Barcelo... Read More
In this blog post, I describe how I had students create their own cartoon depicting microbiological ideas and concepts that most tickled their fancy. I did this on their final exam, and the students came up with really interesting and entertaining ideas. IT's always interesting to see what stu... Read More
Dear Vincent and hosts of TWIM,
I am a long time listener and fan of your weekly TWIM podcasts. I really enjoyed the latest episode in which you discussed a paper by Kelly Wrighton and colleagues, and was especially... Read More
As reported in a new study in the the journal Proceedings of Royal Society B: Biological Sciences, scientists have taken a step toward identifying the genetic mechanisms that makes some lowland leopard frogs in Arizona resistant to Batrachochrytrium dendrobatridis (Bd) infections that cause the ...

A new class of drugs has shown promise for treating the bacteria that cause legionnaires' disease, a potentially fatal lung infection. Read More
I teach Microbiology at the University of Puget Sound every fall semester. The swiftly changing field of microbiology has depth and breath...and I was interested to learn what my students thought of the topic at the beginning of the first day of class. We will revisit this subject at the end o... Read More
Researchers at the University of California, Berkeley, who have discovered more than 1,000 new types of bacteria and Archaea over the past 15 years lurking in Earth's nooks and crannies, have dramatically rejiggered the tree to account for these microscopic new life forms. Read More
Lung ultrasound has been shown to be highly effective and safe for diagnosing pneumonia in children and a potential substitute for chest X-ray, according to a study conducted at the Icahn School of Medicine at Mount Sinai. Results are currently published in the medical journal Chest. Read More
CHAPEL HILL, N.C. - Investigators in the Division of Infectious Diseases at the University of North Carolina School of Medicine have clearly demonstrated that HIV infects and reproduces in macrophages, large white blood cells found in the liver, brain and connective tissues of the body. This dis... Read More
CHAMPAIGN, Ill. -- A new study offers the first atomic-scale view of an interaction between the HIV capsid - the protein coat that shepherds HIV into the nucleus of human cells - and a host protein known as cyclophilin A. This interaction is key to HIV infection, researchers say. Read More
Bacillus anthracis had been studied by multiple countries as a potential biological weapon because of the stability of its spores and its ability to cause acute pulmonary disease. While offensive anthrax weapons development programs were halted in the United States and United Kingdom in the ... Read More
Three young inventors and students at Stanford University are working to develop proteins that fight antibiotic resistant bacteria. They are optimistic they have found something that works. The proteins the team is developing attack "something that's essential to bacterial survival". But they wo... Read More
Of all the scientific results that my laboratory has produced over the years, I am most satisfied by those that maximally benefit the field. In this category falls the assay for determining the titer of Zika virus in plaque forming units per milliliter.
In ‘Counting Zika Virus’ I described o... Read More
Researchers at University of California, San Diego School of Medicine have discovered that HIV infection of human immune cells triggers a massive increase in methylation, a chemical modification, to both human and viral RNA, aiding replication of the virus. The study, published February 22, 2016... Read More
Many people with Parkinson’s disease also experience digestive symptoms (like constipation) for some time before their diagnosis. But until recently, research on the degenerative disease and how to treat it has focused on understanding how Parkinson’s works in the brain.
In a new study out th... Read More
Engineers have developed a rapid, low-cost genetic test for Zika. The $2 device, about the size of a soda can, doesn’t require electricity or technical expertise and only needs a bit of saliva. Read More
Scientists from The University of Texas at Austin, the Stanford University School of Medicine and two other institutions have discovered that bacteria have a system that can recognize and disrupt dangerous viruses using a newly identified mechanism involving ribonucleic acid (RNA). It is similar... Read More
I have worked on polio virus in my laboratory at Columbia University for 35 years. When that virus is eradicated--perhaps in the next few years--we will have to destroy all of our virus stocks. When that happens, I can either go home, or find another virus.
When Zika virus stepped into the w... Read More
The TWiV team discusses eye infections caused by Zika virus, failure of Culex mosquitoes to transmit the virus, and replication of norovirus in stem cell derived enteroids.
