There’s no question that foodborne disease is a serious problem. Illnesses from contaminated foods cause over 128,000 hospitalizations and 3,000 deaths each year in the United States. The Centers for Disease Control and Prevention estimates that one in six Americans suffers a food-related illne... Read More
Food-related microbiology can be one of the most fun - or least fun - ways to interact with microbes. In the ‘most fun’ category, scientists and non-scientists alike can use microbes to create delicious foods from fermentative processes; in the ‘least fun’ category, scientists and non-scientists...

How is it that we are we able to devote so little of our personal time and energy to producing or acquiring the healthy, safe food that we consume multiple times every day? A large part of the reason we seldom worry about agricultural output is that most of us benefit enormously from modernized,... Read More
The human microbiome is the diverse population of microorganisms that live on and in the body. Many thrive on the skin and in the mouth, but the majority live in the intestines. Over the last decade or so, microbiologists have become increasingly aware of how a person's microbial mix likely play... Read More
I teach Microbiology at the University of Puget Sound every fall semester. The swiftly changing field of microbiology has depth and breath...and I was interested to learn what my students thought of the topic at the beginning of the first day of class. We will revisit this subject at the end o... Read More
Antimicrobial resistance has been a growing concern in the health care community. But a publication by Chinese researchers in The Lancet Infectious Diseases last fall kicked things up a notch. The work found the mcr-1 gene, which confers resistance to the antibiotic colistin, in Escherichia coli... 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
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

From the twiVivants, follow up on FluMist and Zoster vaccines, Zika virus update, and isolation of a multicomponent animal virus from mosquitoes.
H.P. Lovecraft fan and composer Reber Clark (https://reberclark.bandcamp.com/) collaborated with my undergraduate student Ruth Isenberg and myself on a science+music+HPL video. When a log phase culture of Photobacterium leignothi is poured into a Petri dish, and 10 second exposures are taken ev... Read More
Being a bad recycler implies creating more waste because items aren’t being reincorporated into the production chain. Plastic water bottles can be broken down and turned into new plastic bottles, gardening gloves, or fleece – any of which means less oil needs to be harvested and refined to the p... Read More
In a new paper, researchers debunk the common myth that in the human microbiome, bacteria outnumber human cells 10-to-1. By examining the colon, the researchers estimate that the total number of bacteria in the human microbiome is 38 trillion (for the average 70-kg man). For comparison, the auth... 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
One of the important tasks of Public Health England’s Mycology Reference Laboratory is to identify any newly emerging fungal pathogens that could become a public health risk. In recent months, the lab had tracked several clusters of Candida auris infections in British hospitals. The multidrug-re... Read More
Bitter tasting yogurt or cheese may not make it to your refrigerator, but it is produced and the result of pesky bacteria. The microbial composition of raw milk impacts the quality, shelf life, and safety of processed milk and other dairy products. Controlling the quality of these products is tr... Read More
On Monday, August 1, the US Centers for Disease Control and Prevention recommended that pregnant women not travel to Wynwood, a neighborhood north of downtown Miami, because health officials in Florida had found that mosquitoes there are actively transmitting Zika, a mosquito-borne virus that ca...

The TWiV team takes on an experimental plant-based poliovirus vaccine, contradictory findings on the efficacy of Flumist, waning protection conferred by Zostavax, and a new adjuvanted subunit zoster vaccine.
