The TWiVnauts present another example of an infectious but replication incompetent vaccine, an insect specific arborvirus bearing chikungunya virus structural proteins.
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.
This past weekend, I went to visit a friend and meet his twin toddler boys for the first time. Though both boys eagerly ran around the playground we visited, one was just slightly less active. “He has asthma,” his dad explained to me, “but his brother doesn’t.” Why would two boys with the same e...

The TWiVestigators wrap up 2016 with a discussion of the year's ten compelling virology stories.
The TWiM hosts reveal why phosphorus is essential for fungal brain disease, and how bacteria kill local competitors to favor the evolution of public goods cooperation.
The TWiX cabal discuss sexual transmission of Zika virus in mice, and how immune escape enables herpes simplex virus escape from latency.
One of the important tasks of Public Health England’s Mycology Reference Laboratory is to identify any newly emerging fungal pathogens that could become a public health risk. In recent months, the lab had tracked several clusters of Candida auris infections in British hospitals. The multidrug-re... Read More

The first Microbe meeting, which combines the former general meeting and ICAAC, was a whirlwind of poster presentations, lectures, seminars, book sig... Read More
Biofilms, surface-attached microbial communities encased in an extracellular matrix, are one of the most common macroscopic microbial structures we can see in nature. Biofilms like those seen in pond scum, in dental plaque, or in hot springs, are mixed communities with the members forming both a... Read More
Polio returns to Nigeria after two years - but it turns out it had never gone away.
