Trudy joins the the TWiVlords to discuss new tests for detecting prions in the blood, and evidence showing that foamy retroviruses originated in the seas with their jawed vertebrate hosts at least 450 million years ago.
Hosts: Read More
As the durations of manned space missions increase, it is vitally important to understand the long-term consequences of microbial exposure on human health in closed human habitats. One mission of the Microbial Observatory Experiments on the International Space Station is to examine the traits an... Read More
In recent years, researchers have learned that gut microbiota play a role in a number of human diseases, including Clostridium difficile infection, irritable bowel syndrome, Parkinson’s disease, and autism spectrum disorder. The revelations have scientists hopeful that fecal microbiota transplan... Read More
Misdiagnosis can lead to severe consequences for patients, and is a serious clinical issue. The newly emerging Candida auris requires higher doses of antifungal medications to treat an infection than does C. albicans, highlighting the importance of proper diagnosis. Thus far, the most accurate d... Read More
Many years ago, Homo sapiens mated with Neanderthals. Today a small percentage of our genome remains Neanderthal, and in a study discussed on this episode of the science show This Week in Evolution, we show that some important genes of our innate immune response - the early response against path...

The TWiVites discuss Zika virus seroprevalence in wild monkeys, Zika virus mRNA vaccines, and a gamete fusion protein inherited from viruses.
Just like you and me, bacteria have ‘favorite’ foods – though in the case of bacteria, 'favorite' translates to those which are energetically favorable or most accessible. Different bacteria have different preferences, based on their environments and the neighboring microbes that compete for or ... Read More
The anaerobic, Gram-positive Clostridium difficile is a big problem. It causes rampant diarrhea and tissue necrosis, with more than 150,000 annual cases in the United States alone. Many of the disease manifestations of C. difficile are mediated by two exotoxins that C. difficile produces: TcdA a... Read More
While detection and reaction to light sources is a well-known process in environmental organisms exposed to diurnal light cycling, light detection also affects the biological processes of human pathogens. The human pathogen Acinetobacter baumannii, a microbe associated with hospital-acquired inf... Read More
In this blogpost, take a tour of some of the artwork that students in my classes have made. I believe that creative approaches can complement learning! Read More
I like to encourage my students to explore the intersection between art and microbiology. Science + art = awesome! In any event, in this blog post, I describe two microbial art competitions in my microbiology course at the University of Puget Sound. I think my micronauts did some remarkable w... Read More
mSphereDirect is an exciting new pathway to publish your research! This groundbreaking new submission path puts you in control of getting your original research reviewed and published as soon as possible. We’ve prepared the most important things to keep in mind while preparing your manuscript s... Read More
Welcome back to Dispatches from ASM Microbe! Today we’ll continue Microbe 2016 highlights of the microbiome, focusing on the non-human microbiome research being presented during the conference.
As mentioned yesterday, commencement of the National Microbiome Initiative was met with great exci... Read More
Many mBiosphere readers will know that the influenza A virus infects multiple species, and this ability to infect birds, humans, and other mammals such as pigs is one of the ways virions can exchange genetic information, leading to new viruses able to cause major outbreaks. However, few mBiosphe... Read More
Food microbiology is an important issue we cover on this blog, because food safety is vital to prevent foodborne illness. The use of technologies like whole-genome sequencing help identify and pinpoint the source of microbial contaminants, but how do microbes become contaminants in the first pla... Read More
This episode: Insect gut microbes can be engineered to act as birth control, population control, or disease control for bugs!

An Applied and Environmental Microbiology study found ubiquitous contamination of chicken products in the United States with clinically relevant E. coli strains, which has implications for urinary tract infection transmission. A new book from ASM Press describes UTIs in detail, from virulence me... Read More
No matter the niche field a scientist pursues, there is one aspect of almost all career paths that scientists have in common: teaching. Whether lecturing a quorum of undergraduates about bacterial genetics, mentoring a research fellow as they learn the lab protocols, or presenting an invited lec... Read More
So far in this series I’ve written a good deal about our work on Zika virus, but I have said little about the people who are doing the science.
My lab at Columbia University Medical Center is very small, consisting of three people—Amy Rosenfeld, Audrey Warren, and me. Let me tell you about ... Read More
