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
On this episode of Virus Watch we cover three Zika virus stories: the first human trial of a Zika virus vaccine, the first local transmission of infection in the United States, and whether the virus is a threat to participants in the 2016 Summer Olympic and Paralympic Games. 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...

Robots help sort patient samples, test clinical specimens, and analyze the results. Now a study shows that robots, in the form of drones, can help move our samples from place to place, with little effect on the analytical outcome.
Drone transport made a news splash when Amazon proposed using ... Read More
Though both gingivitis and periodontitis are diseases of the gums, the related ailments are not simply different severities of the same disease, finds a new study published in Applied and Environmental Microbiology. Researchers confirmed this by investigating the bacterial composition of the sup... Read More
Mosquito saliva, which is injected into the host as a mosquito probes for a blood vessel, contains a collection of chemicals which include anticoagulants to prevent blood clotting, vasodilators to keep blood vessels wide, and anesthetics to prevent us from sensing the mosquito. Saliva also conta... 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
Vincent Racaniello of the This Week in Virology podcast interviews David Baltimore, PhD, California Institute of Technology, about his career and professional experience in the field of virology. Baltimore received a 1975 Nobel laureate in Physiology or Medicine for work on the interaction betwe... Read More
Dr. Michael Diamond, 2016 Elizabeth O. King Lecturer, has worked for the past two decades investigating how viruses work, with a goal of defining basic principles of pathogenesis and host immune restriction. His talk in this podcast focuses on how his laboratory has studied three emerging mos... 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
This episode: Predatory bacteria have a particular protein that protects them from their own prey-damaging enzymes!

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
Taxonomic profiling is a challenging first step when analyzing a metagenomic sample. This work presents a method that facilitates fine-scale characterization of the presence, abundance, and evolutionary relatedness of organisms present in a given sample but absent from the training database. We ... Read More
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
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
From the twiVivants, follow up on FluMist and Zoster vaccines, Zika virus update, and isolation of a multicomponent animal virus from mosquitoes.
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
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
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
