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
This episode: Predatory bacteria have a particular protein that protects them from their own prey-damaging enzymes!

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.

This episode: Proteins from gut bacteria seems to affect hunger and satiety in their (rodent) hosts!
(7.7 MB, 8.3 minutes)
Insight into the biology of rhinovirus C from cryo-electron microscopy, and a novel antibiotic from a commensal bacterium that grows in the human nose, from the doctors of TWiM.
I'm a graduate student working in mycoplasmology and I must say I've been overjoyed to hear the past few episodes mention our tiny friends!
Elio's mention of their unique mechanism of moving ("Gliding Motility") made... Read More
In Zanzare, the new comic from Cimaza (www.cimazacomics.com/), we are plunged head-first into the global mystery of the Zika virus. We meet the mosquitoes (in Italian: zanzare) implicated in its spread; but the insects plead their innocence, saying it's all a misunderstanding. They lay their cas... Read More
Soil microorganisms carry out key processes for life on our planet, including cycling of carbon and other nutrients and supporting growth of plants. However, there is poor molecular-level understanding of their functional roles in ecosystem stability and responses to environmental perturbations.... Read More
"Hivi and his team of viruses (Ebola, Pox,..etc) believe they can win the battle, but the Virologists (who are real famous professors) beat them. However, new viruses pop-up, it will be a long battle. This makes the story very interesting and ever so engaging."
