My experience with Foldscope, the paper microscope. See the images of insects, parasites, vegetal and animal tissues and cells, yeast, bacteria and (almost) virus (the cytopathic effect), with Foldscope, the paper microscope (text in Spanish). Read More
Exposure to reactive oxygen species, exposure to ionizing radiation, exposure to UV light – all of these are dangerous because of their potential to alter DNA sequences. Changes in DNA can affect a protein coding sequence, potentially influencing its function, but changes in regulatory regions c... Read More
Imitation may be the sincerest form of flattery, but it can also be the easiest way to make a buck. That’s the primary motivation for camouflaging within an already-established brand: Sunbucks, McDowell’s, and Mountain Lightening all rely on brand recognition – of a brand that isn’t their own. W...

Antimicrobial resistance has been a growing concern in the health care community. But a publication by Chinese researchers in The Lancet Infectious Diseases last fall kicked things up a notch. The work found the mcr-1 gene, which confers resistance to the antibiotic colistin, in Escherichia coli... Read More
On this episode of Virus Watch we cover three Zika virus stories: the first human trial of a Zika virus vaccine, the first local transmission of infection in the United States, and whether the virus is a threat to participants in the 2016 Summer Olympic and Paralympic Games. Read More
Actinobacteria are the bacterial phylum responsible for production of many clinically-relevant antibacterial compounds. Streptomyces is a soil-dwelling genus of actinobacteria that produces drugs like neomycin and chloramphenicol. Despite deriving many antibiotics already from Streptomyces, coul... Read More
Evolution proceeds by selection of mutants that arise by error-prone duplication of nucleic acid genomes. It is believed that mutations that are selected in a gene are dependent on those that have preceded them, an effect known as epistasis. Analysis of a sequence of changes in the influenza vir...

On Monday, August 1, the US Centers for Disease Control and Prevention recommended that pregnant women not travel to Wynwood, a neighborhood north of downtown Miami, because health officials in Florida had found that mosquitoes there are actively transmitting Zika, a mosquito-borne virus that ca...

Change does not come easily to most organizations, let alone to one with more than a century of history. Indeed, twice before ASM tried—and failed—to change its governance structure. This time, ASM members embraced change, realizing that ASM must become more modern and more nimble in its decisio... Read More
This is a paper from the Geomicrobiology lab at the Jackson School of Geosciences at the University of Texas at Austin. It was recently published in a special issue of Geomicrobiology Journal focused on geomicrobiology of subsurface microorganisms in cave environments.
In this study we attemp... Read More
Microbiome research has revealed that there are good guy and bad guy bacteria living together in complex communities on our skin, in our mouths, throughout our guts and pretty much everywhere in between. But what do you call a good guy bacterium that is aiding and abetting a disease culprit?

Experiments with the most dangerous human viruses, such as Ebola virus and Lassa virus, are carried out in biosafety level 4 (BSL-4) laboratories. Since visiting the Northeast Infectious Diseases Laboratory BSL-4 and releasing the documentary video Threading the NEIDL, I was given the opportunit... Read More
Veintinueve profesores e investigadores de 20 universidades y centros de investigación van a colaborar para impartir el primer curso mundial online gratuito vía Twitter sobre microbiología. La iniciativa está coordinada y organizada por el grupo de Docencia y Difusión de la Microbiología de la S... Read More
Have you ever gone to the beach, ready for a day of sun and sand, only to find a warning sign? One of the most common reasons beaches close is due to the presence of coliform bacteria. These indicator bacteria, such as Escherichia coli, are used as markers for fecal waste, since their presence c... Read More
Jennifer joins Vincent, Elio, and Michael to talk about the work of her laboratory on how a respiratory virus enhances bacterial growth by dysregulating nutritional immunity.
Group: Group IV ((+) ssRNA)
Species: Zika virus
Structure of Zika Virus
•The virion is approximately 40 nm in diameter with surface projections that measure roughly 5-10 nm.
•Nucleocapsid is 25-30 nm in diameter surrounded by a host-membrane derive... Read More
Each Fall, I teach a freshman writing class about symbioses and parasitism. I was very lucky to get some pretty famous people to "Skype" or "Google Hang Out" in to visit my class. Last Fall, one of my "tele-speakers" was the fabulous science writer and very funny fellow Ed Yong. The students ... Read More
I have long believed that there are many ways for students to learn. In several of my classes, I encourage students to use "creative" approaches to explore course concepts. In the Fall of 2015, here is what my micronauts in my Microbiology course at the University of Puget Sound came up with..... 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.
Having worked on viruses for over 40 years, I know a fair number of people in the field, and I am amazed at how many of them have started to work on Zika virus. What exactly is attracting virologists to this emerging virus?
There are probably many reasons why Zika virus would be of interest t... Read More
