Vincent, Elio and Michele wind up a year of microbial podcasts with a story about the lack of resistance to a crop antifungal compound, and how a bacterium uses a molecular caliper to measure membrane thickness.

The TWiVaniellos discuss a thermostable poliovirus empty capsid vaccine, and two cell genes that act as a switch between entry and clearance of picornavirus infection.
One of the most dangerous places for an infection to occur is in the bloodstream. Septicemia, when microbes are present in the blood, not only allows bacteria access to other internal organs through the highway of our circulatory system, but also can cause a massive inflammatory response, leadin...

Clostridium difficile is a dangerous superbug. Infections with this bacterium can cause life-threatening diarrhea, and they are most likely to affect the elderly or people with health problems who spend a lot of time in hospitals (where C. difficile flourishes). The Centers for Disease Control a... Read More
We’ve previously covered the importance of diagnostics in disease control and treatment. This is vital to controlling disease progression and transmission, but epidemiology studies can’t always show how a disease progresses or transmits. This is where scientists need a well-characterized animal ... 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
Virus Watch is a new weekly video series that explores the amazing world of viruses. This week: the latest research on Zika virus, including finding virus in Brazilian monkeys, dengue antibodies helping Zika virus infection, and brain organoids to study how Zika virus causes microcephaly. Read More
If it looks like a duck and quacks like a duck, it’s likely a duck – so goes the saying that illustrates the simplest explanation is usually the right one. But what about duck decoys used in conjunction with bird calls? Misidentification can be a deadly error – and the same goes for microbes. Mi... Read More
Several papers published in Genome Announcements recently describe the sequences of new Zika virus isolates. Scientists have known the genomic sequence of at least one Zika virus isolate since 2007, but continue to publish newly isolated strains. What is the importance of these additional sequen...

The human microbiome is the diverse population of microorganisms that live on and in the body. Many thrive on the skin and in the mouth, but the majority live in the intestines. Over the last decade or so, microbiologists have become increasingly aware of how a person's microbial mix likely play... Read More
The TWiVrific gang reveal how integration of a virophage into the nuclear genome of a marine protozoan enhances host survival after infection with a giant virus.
Given that the holidays are right around the corner, many of us will be trying to eat healthy outside of celebratory meals, and that includes turning to salad as a healthy meal option. Salads do provide fresh nutrients, but new research in Applied and Environmental Microbiology suggests pre-cut ... Read More
As we highlighted in our previous blog, antibiotic stewardship – the careful use of appropriate antibiotic administration – can have positive effects. A small change from a difference in clinical lab reporting led to less drug use, which led to fewer drug-resistant infections. When we think of a... Read More
How do you identify an unknown microbe? If you’ve taken an introductory microbiology lab course in the past twenty years, chances are you were assigned an unknown bacterium that you had to identify through differential media and biochemical assays. Newer techniques like qPCR are being standardiz... Read More
A central pursuit of microbial ecology is to accurately model changes in microbial community composition in response to environmental factors. This goal requires a thorough understanding of the drivers of variability in microbial populations. However, most microbial ecology studies focus on the ... Read More

Is the way to treat heart disease through a person's stomach? According to a new study, the answer is yes. Researchers have found that a compound found in red wine, resveratrol, reduces the risk of heart disease by changing the gut microbiome.
Cardiovascular disease remains the leading cause ... 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
