Examining Aspergillus fumagatus on the Space Station

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

Toward better understanding of fecal microbiota transplants

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

In search of a better diagnostic assay for emerging fungal pathogen Candida auris

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

TWiEVO 8: Everyone’s a little bit Neanderthal

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...

Small RNAs regulate Bacteroides nutrient use

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

Disarming a pathogen's ability to cause disease

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

Global Transcriptional Response of Acinetobacter baumannii to Light Exposure

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

Student-Made #SciArt In My Microbiology Lab

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

Microbial Awards Season in Biology 350!

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

Outbreak of H7N2 Flu in Cats

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

How to be a successful food borne pathogen: step 1, grow on food

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

Connecting the Food Supply and Urinary Tract Infections

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

ASMCUE Happenings 2016

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

A Tiny Zika Laboratory

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
