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
A new blog written by undergraduate students from the School of Genetics and Microbiology, Trinity College Dublin features Vincent Racaniello, PhD, host of This Week in Virology.
"Most students studying science at university will inevitably become familiar with the names and works of a wide r... 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
The multi-dimensional TWiV-brane brings you the entries in the haiku/limerick contest, and explain how a giant virus infects a host within another host (it has to do with predators!).
Hosts: Read More
Polio returns to Nigeria after two years - but it turns out it had never gone away.
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
From the twiVivants, follow up on FluMist and Zoster vaccines, Zika virus update, and isolation of a multicomponent animal virus from mosquitoes.
The molecular order of events is important in virulence, and a new paper published in the Journal of Bacteriology looks at the order of events necessary for bacterial toxin delivery to a host cell. Specifically, the authors looked at the assembly of Shiga toxin, produced by Shigella dysenteriae ... Read More
This episode: Cyanobacteria in biocrusts produce pigments that heat their surroundings up to 10 degrees hotter!

It has been speculated that the development of neurological disease and fetal abnormalities after Zika virus infection may be due to the presence of antibodies against other flaviruses that enhance disease. In support of this hypothesis, it has been shown that antibodies to dengue virus enhance... Read More
In this new video episode of Virus Watch, you'll see how the Zika virus particle is built, and how it binds to an antibody that blocks infection. All in gorgeous three dimensional views provided by recent structure studies. Read More
The TWiPniks docs solve the case of the Female from Peru with Epistaxis, and discuss the effect of community deworming on immunosuppression.
"Hivi and his team of viruses (Ebola, Pox,..etc) believe they can win the battle, but the Virologists (who are real famous professors) beat them. However, new viruses pop-up, it will be a long battle. This makes the story very interesting and ever so engaging."

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...

For the article letter about microbial batteries, I think CV refers to Capacitance times Voltage, which is stored charge. In electronics, current is abbreviated I not C.
The claim in the letter got me thinking about microbial batteries and I wrote ... Read More
Mapping and identifying all the microbes across New York City is no small feat. Just ask Jane Carlton. About three years ago, Carlton, director of the Center for Genomics and Systems Biology, and professor of biology, at New York University and colleagues won an NYU grand challenge grant for the...

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
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.

Because of its safety, efficacy, and affordability, chloroquine remains the treatment of choice for all Plasmodium species, except in regions with chloroquine-resistant P. falciparum. Chloroquine-resistant protists are treated with combination therapy, which includes artemisinin-derived molecule... 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
