A common denizen of the undergraduate microbiology laboratory, Serratia marcescens is well known for the production of a bright red pigment, prodigiosin. Prodigiosin has been investigated over many years for its possible antimicrobial, antifungal, and even antitumor effects. Still, the relevan... 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
The discovery of antibiotics (also referred to as antimicrobials) is perhaps the most revolutionary outcome in the medical sciences during the twentieth century, and has allowed medical practitioners to treat a wide range of bacterial infections; and therefore, antimicrobials are the most common...

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
So another Earth Day has come and gone. How did you spend yours? If you spent the entire day asleep, you used about half a kilogram of oxygen. Since I assume that you are alive and kicking, you probably consumed more oxygen than that. If you went about your normal business during the day, you pr... Read More
In fall 2015, a new human hepegivirus (HHpgV-1) was identified by using a novel, high throughput sequencing technique. Concerns were raised that this virus was found in blood to be used for transfusions, potentially passing on the infection. But without tools to test for its presence, there was ... Read More
Background: Acinetobacter baumannii is commonly resistant to nearly all antibiotics due to presence of antibiotic resistance genes and biofilm formation. In this study we determined the presence of certain antibiotic-resistance genes associated with biofilm production and the influen... Read More
Nitin Phadnis joins Nels and Vincent to explain how he identified a gene that is responsible for male inviability in hybrids from a cross between two species of fruit flies. Read More
“Wikipedia is the first place people go for information about science – and everything else,” says John Tracey, Research Assistant in Education & Outreach at the Simons Foundation. The Simons Foundation has teamed up with Google to sponsor the Wikipedia Year of Science 2016, an initiative to inc... Read More

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
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
Polio returns to Nigeria, Zika virus spreads in Miami, and virus infection of plants attracts bumblebees for pollination, from the virus gentlepeople at TWiV.
I have worked on poliovirus for over thirty-six years, first as a posdoctoral fellow with David Baltimore in 1979, and then in my laboratory at Columbia University. The end of that research commences this year with the destruction of my stocks of polioviruses. Read More
How do we define the genetic makeup of an individual? Is it the genetic material found in each cell of that individual (that’s not entirely accurate; mutations and recombinatorial differences can lead to multiple genomes in one individual). And what about the genes carried by our microbiome? The... 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
ASM Microbe is the new conference that merges the former General Meeting with the Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) to make one microbial sciences-packed meeting with something for everyone. Why institute one new meeting instead of maintaining two separate ... Read More
Host: Jeff Fox with special guests, Carolyn Shore and Ruben Tommasi.
Carolyn Shore of Pew Charitable Trusts in Washington, D.C., and Ruben Tommasi of Entasis Therapeutics in Waltham, Massachusetts, talk with Jeff Fox about what’s needed to identify and develop new antimicrobial agents... Read More
If the DNA sequence of a cell is like the operating system of a computer, then the smallest cellular OS has just been written. Called Syn3.0, it encodes everything needed to make a viable, autonomously replicating cell.
Mycoplasma is a genus of bacteria that are the smallest known free-living... Read More
Read in near real-time a virologist's experiments on Zika Virus. Now with its fourth post the Zika Diaries aims to illuminate the public on what it takes to do research on this emerging outbreak. From the Racaniello Lab at Columbia Univ. -
"Now that my laboratory obtained a number of differe... 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
