Students are the focus of the Annual Biomedical Research Conference for Minority Students (ABRCMS) meeting, held most recently November 9-12, 2016, in Tampa, Florida. Undergraduate and postbaccalaureate students make up over half the roughly 4,000 program participants, and many participants belo... 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. -

This is our way to wish a Happy New Year to all the Microbiologists community!
The numbers were made as follows:
2: E. coli, MacConkey Agar plate incubated at 37 C, 20h.
0,1: MRSA on blood Agar plate, incubated at 37 C + 5%CO2.
7: M. fortuitum on Chocolate Agar plate, incubated at 37 C + 5%... Read More
Washington, DC – August 8, 2016 – For the first time in Brazil, a particular antibiotic resistance mechanism conferring resistance to the important antibiotic, colistin, has been detected in a human. It was in a strain of Escherichia coli that was isolated from a diabetic patient’s foot infectio... Read More

Chemist Pieter Dorrestein’s laboratory group has been developing mass spectrometry methods to look at what molecules are produced by microbes interacting in a petri dish. But recently, the group jumped out of the dish and into the dirt—to analyze a soil-dwelling lichen and discover how the molec... Read More
The last time you had a stomach bug, you probably didn’t feel much like eating. This loss of appetite is part of your body’s normal response to an illness but is not well understood. Sometimes eating less during illness promotes a faster recovery, but other times—such as when cancer patients exp... Read More
In 3500 BCE, Egyptian rulers built a menagerie of exotic creatures within the ancient capital of Hierakonpolis. Archaeologists have found 112 animal skeletons at this site: the first zoo on Earth. But from this earliest exhibition of the natural world through today’s most famous animal displays,... Read More
The Centers for Disease Control and Prevention has reported that the wily Neisseria gonorrhoeae bacteria may be developing resistance to the only two antibiotics left that can cure the sexually transmitted disease.
The drugs, azithromycin and ceftriaxone, are used in combination to treat gonorr... Read More
In this episode of Virus Watch, I explain how mosquitoes spread viruses. We’ll look at how a mosquito finds a host, how it finds a blood vessel, and how it delivers viruses to a new host. Don’t blame mosquitoes for viral diseases: it’s not their fault!

Our work on Zika virus has utilized two different antibodies to detect Zika virus replication within cells. I described one antibody, directed against double-stranded RNA (dsRNA) in a previous article. A second antibody directed against a Zika virus protein has also been useful...

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
The World Health Organization downgraded the spread of Zika virus from a Public Health Emergency of International Concern on November 22nd, but Zika virus infection remains an important emerging infection with an incompletely understood infection cycle. The better scientists understand how the v... Read More
Washington, DC – August 2, 2016 – Adjuvants – ingredients added to vaccinations for influenza and other viruses to help boost their effectiveness – can increase a host’s immune response but not enough to protect the obese against the ill effects of the flu, according to a mouse study published t...

A family of highly drug-resistant and potentially deadly bacteria may be spreading more widely—and more stealthily—than previously thought, according to a new study from Harvard T.H. Chan School of Public Health and the Broad Institute of MIT and Harvard.
Researchers examined carbapenem resi... Read More
A research team at Washington University School of Medicine in St. Louis has established a mouse model for testing of vaccines and therapeutics to battle Zika virus. 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
Every 18 seconds someone dies from tuberculosis - it is the world’s most deadly infectious disease.
Mycobacterium tuberculosis, the causative agent of tuberculosis (TB), has infected more than one-third of the human population with an annual death toll of approximately 1.5 million people.

Communication of experimental results via publishing is one of the most important steps of the scientific method; if you don’t share your results, how will knowledge within a field grow? A well-written article contextualizes the author’s data into a broader scientific landscape, which allows rea... Read More
A surprisingly specific genetic portrait of the ancestor of all living things has been generated by scientists who say that the likeness sheds considerable light on the mystery of how life first emerged on Earth.
This venerable ancestor was a single-cell, bacterium-like organism. But it has a... Read More
