Today it is well known that viruses may contain DNA (poxvirus, mimivirus) or RNA (influenza virus, Zika virus), but for many years it was thought that genomes were only made of DNA. The surprise at finding only RNA in a virus is plainly evident in a 1953 letter from Harriett Ephrussi-Taylor to J... Read More

We at mBiosphere know you are busy, reader! With various gels, analyses, programs, and classes to run, not to mention reports, abstracts, and grants to write, we know there are many demands made on our readers’ time (plus, dinner to plan, laundry to fold, the dog to walk...wait! Don't go! You ha... Read More
Like us, bacteria have their own microbial attackers, in the form of bacteria-specific viruses called bacteriophage, or phage. These phage come in a variety of flavors but can be broadly categorized into virulent, which immediately begin to replicate and lyse (burst) the infected cell quickly, a... Read More

Evidence is mounting that Zika virus is neurotropic (able to infect cells of the nervous system) and neurovirulent (causes disease of the nervous system) in humans. Read More
News headlines highlighting an outbreak of a vaccine-preventable disease often leave readers shaking their heads. These diseases – measles, chickenpox, whooping cough – could have been prevented if only the infected children had been vaccinated. Right? Well, in the case of whooping cough, the si... Read More
How does a single-celled organism ‘know’ how to respond to its environmental conditions? Understanding microbial cell signaling is one way to determine how bacteria will react in a particular setting. In the past decade, researchers have revealed a significant role for cyclic-di-GMP in bacterial... Read More
This episode: Amoebas in soil gang up on and eat much larger roundworms!
(10.5 MB, 11.3 minutes)
Not long after the appearance of an outbreak of viral disease, first scientists, and then newswriters, blame it all on mutation of the virus. It happened during the Ebolavirus outbreak in West Africa, and now it’s happening with Zika virus.
The latest example is by parasitologist Peter Hotez,... Read More
Earlier this month, two new ASM research journals had their official launch. mSphereTM and mSystemsTM had both published articles on their interim websites in November and December 2015 – some of which have been highlighted here on mBiosphere. On February 2nd, the journals went live on their per... Read More
The microbiome of hibernating bears, and zebrafish as a model for bacterial sepsis feature in this animal-centric episode of TWiM hosted by Vincent, Michael, and Michele.

The TWiPtastic trio solves the case of the Surfer from Switzerland, and reveal how taste-chemosensory tuft cells in the gut regulate immune responses to parasites.
What kinds of microbes do you associate with hot springs? Maybe microbial mats? Thermus aquaticus and the discovery of Taq polymerase? Archaea, previously (and erroneously) thought to be strict extremophiles? Viruses may not be the first microbial subtype that springs to mind (pun intended) but ... Read More
The previous post mentioned the onset of antibiotic resistance as one of the scarier, if less sensationalist, outbreaks of our time. We generally discuss antibiotic resistance in medically relevant microbes (on this blog and in the news), where resistance means the ability of disease-causing mic... Read More
In episode #3 of the new science show This Week in Evolution, Nels and Vincent examine another important driver of evolution: recombination. The results of two papers in which the process is studied in finches and in yeast lead to the unexpected conclusion that recombination evolves more slowly ... Read More
