Bacteria acquire and spread genetic information through several means. Some bacteria form a long, thin tube called a pilus, mediating transfer of DNA by direct cell-to-cell contact, in a process known as conjugation. Some bacterial take up environmental DNA and incorporate it into their existing... Read More
I had my #Bio350 micronauts write one page "Nanobiographies" of their #MicrobialTermPapers. I'm very pleased. Read More
The Fellowship of the Virus trace the early history of HIV in North America, based on genome sequences obtained from late 1970s archival sera, which also reveal that Gaetan Dugas was not Patient Zero.

The call for abstracts is now open for Microbe 2017, the premier microbiology conference hosted by the American Society for Microbiology. This is your opportunity to submit your important research in the microbial sciences to the largest scientific audience, with a 50% higher chance of presentin... Read More
The study researchers found that placing a small, detoxified amount of E. coli in the guts of mice led to an increase in levels of leptin - known as the "satiety hormone."
Within 7 days of the increase, the number of sweet taste receptors on the rodents' tongues reduced, diminishing their ap... Read More
The TWiVsters explain how superspreader bacteriophages release intact DNA from infected cells, and the role of astrocytes in protecting the cerebellum from virus infection.
A benefit of the voluminous wealth of research produced is that it allows us to stand on the shoulders of giants – we can take advantage of established facts, tools, and datasets. This may mean using a mutant library to find genes in your organism that are important for the process you study; ac... Read More
In some individuals, an influenza A virus infection can cause asymptomatic Staphylococcus aureus (S. aureus) to travel to the lungs where it can trigger severe, sometimes deadly, secondary pneumonia. S. aureus is one of the most common causes of secondary bacterial pneumonia in cases of seasonal... Read More
At St. Jude Children’s Research Hospital in Memphis, Tenn., scientist Stacey Schultz-Cherry has been studying the impact of obesity on influenza severity.
“We saw during the 2009 flu pandemic that there’s an epidemiological link between people getting severe flu and being obese,” says Schultz... Read More
The opening ceremony for the Summer Olympics 2016 will be held this Friday, marking the onset of two weeks of competition between the world’s best athletes. The world has been focused on Brazil and its preparedness – not only for the infrastructure required for the games, but also for any potent... Read More
The Gram-positive bacterium Enterococcus faecium is a member of the ESKAPE pathogens for which drug resistance has been a growing problem. How E. faecium becomes drug resistant has been a long-standing question, and is the focus of a new study now available in Antimicrobial Agents and Chemothera... Read More
Function is often thought of as the tradeoff for high fashion, but who says you can’t have both? Fawn Jordan, 2016-2017 DC Fashion Incubator Designer in Residence, is seeking to unite the two to help protect women against potentially Zika-transmitting mosquitoes. Her recent collection combines t... Read More
As part of its Microbiology of the Built Environment initiative, the Alfred P. Sloan Foundation started funding projects a few years ago that touched on the interaction of microbiology with architecture, buildings or, in the case of Curtis Huttenhower, PhD, an associate professor of computationa...

Microbial communities are essential drivers of soil functional processes such as nitrification and heterotrophic respiration. Although there is initial evidence revealing the importance of soil type in shaping microbial communities, there has been no in-depth, comprehensive survey to robustly es... Read More
In the year 2000, Kathleen Alexander, DVM, PhD, now a professor, at the Department of Fish and Wildlife Conservation, Virginia Tech, Blacksburg, Virginia, was working as a government veterinarian in Botswana, when a sickly banded mongoose wandered onto the grounds where she worked. When the mamm... Read More
Tomorrow begins a Special President’s Edition ASM Conference, hosted by the American Society for Microbiology in collaboration with the American Society for Virology. The conference, “What Does the Biology of Flaviviruses Tell Us About Zika: The Importance of Fundamental Virus Biology” highlight... Read More
Colony collapse disorder (CCD) has caused such a profound drop in honeybee populations that even the U.S. Congress is addressing the issue: Senator Jeff Merkley (D-Oregon) has proposed the Pollinator Recovery Act to preserve pollinator habitat. The rapid decline in these important pollinators af... Read More
My undergraduate student Ruth Isenberg has made real progress adapting a GoPro camera to help us watch microbial interactions. Here are two swimming foci of Photobacterium leignothi encountering one another! Read More
Marine plastic debris is a growing concern that has captured the general public’s attention. While the negative impacts of plastic debris on oceanic macrobiota, including mammals and birds, are well documented, little is known about its influence on smaller marine residents, including microbes t...
