The TWiVeroos examine a reverse spillover of Newcastle disease virus vaccines into wild birds, and identification of a protein cell receptor for murine noroviruses.
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
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
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

The TWiVites discuss Zika virus seroprevalence in wild monkeys, Zika virus mRNA vaccines, and a gamete fusion protein inherited from viruses.
The TWiVsters describe a new animal model for MERS coronavirus-induced acute respiratory distress syndrome, produced by CRISPR/Cas9 editing of the mouse gene encoding an ortholog of the virus receptor.

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
This episode: Bacteria in mosquito cells can block transmission of Zika virus!

Perhaps with more enthusiasm than originality, I feel compelled at the end of the year to look back on what has happened in my life. The compulsion is even stronger this December, since the end of the calendar year coincides with my first year at the helm of ASM as its CEO.
When I joined AS... Read More
While walking through your house, you drop a granola bar you were eating. Quick – do you pick it up and eat it? Is the ground too dirty to eat from? Does the amount of time the food sits on the ground matter? Will more microbes gather onto the snack as you decide whether or not to continue noshi... Read More
The sages of TWiV explain how chronic wasting disease of cervids could be caused by spontaneous misfolding of prion protein, and the role of the membrane protein Axl in Zika virus entry into cells.

Recently, one of the Journal of Bacteriology Classic Spotlight series highlighted the numerous studies on bacterial spores that have been published in the journal throughout the years. Bacterial endospores, the resilient and relatively quiescent bacterial structures first identified in the 1800s... 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
This episode: Some bacterial species use multiple strategies within a single population to deal with environmental challenges!

The TWiV gurus describe how to use an orthogonal translation system to produce infectious but replication-incompetent influenza vaccines.
Here, we present the results of our pioneering experience teaching a full Basic Microbiology course via Twitter (#microMOOCSEM), consisting of 28 lessons of 40-45 minutes duration each, at a tweet per minute rate during 10 weeks. Read More
“Stefano, you seem like a smart person. Can I ask you why you decided to take a job with a scientific society?” I had just helped myself to a slice of a very sharp Stilton cheese, after a wonderful dinner supported by wonderful wine. All of a sudden the Stilton seemed even sharper. The question ... Read More
Star Wars – an epic story of war between the forces of good and evil in a galaxy far, far away. The Death Star – the ultimate weapon of destruction. The story is science fiction, but it could be considered an analogy for the constant battle between our immune system and microbial pathogens. Beli... Read More
