What does the structure reveal about a colony collapse disorder-associated virus

Colony collapse disorder (CCD) has caused such a profound drop in honeybee populations that even the U.S. Congress is addressing the issue: Senator Jeff Merkley (D-Oregon) has proposed the Pollinator Recovery Act to preserve pollinator habitat. The rapid decline in these important pollinators af... Read More

TWiV 410: Hurricane Zika

Sharon and Scott join the TWiV team to talk about their work on dengue antibody-dependent enhancement of Zika virus infection, and identifying the virus in mosquitoes from Miami.

Cloning competition drives student and mentor excellence

Mentoring scientific teams in a project-oriented competition, like engineers can do through the ASCE Concrete Canoe National Competition or the SAE Supermileage Competition, is rare in the microbial sciences. Mentoring a team through this experience allows scientists impart different skills than... Read More

TWiV 423: Dry, well formed, and light brown

The TWiV academia discuss induction of diarrhea by the capsid protein of an astrovirus, and association of a fungal RNA virus with white-nose syndrome of North American bats.

And now for something completely different: optimistic news from the world of antibiotic stewardship

There’s no way to avoid the news of a growing concern for drug-resistant infections. In both life-threatening and relatively superficial infections, the ability to successfully treat microbial infections with antimicrobials is decreasing. Our only recourse is to use the drugs we have carefully w... Read More

High protein diet could reduce obesity in dogs

“There are many gut microbiome studies on humans and rodents, but not a whole lot on dogs, in particular,” says Johnny Li, a computational biologist at the Nestle Purina PetCare Company, in St. Louis. He recently led a study on the connection between diet and intestinal bacteria on 64 dogs — 32 ... Read More

TWiV 427: It was a DURC and UV light

The TWiVoids discuss the March for Science, the GOF moratorium, and a classic virology paper on mapping the gene order for vesicular stomatitis virus.

Microbial Genomics and the Future of Food Microbiology

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

Onward toward a Zika vaccine

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...

Microbes in Raw Milk Influenced by Dairy Cow Environment

Raw milk collected from dairy farms has to travel to processing facilities before it is transformed into the delicious dairy products we consume. Because the milk from many dairy cows is collected together, any contamination issue from a single animal can lead to spoilage or contamination. How r... Read More

Researchers Identify Multidrug-resistant E. coli Bacteria from a New Jersey Patient

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

Unlocking cryptic Strepomyces genes in the search for potential new antibiotics

Actinobacteria are the bacterial phylum responsible for production of many clinically-relevant antibacterial compounds. Streptomyces is a soil-dwelling genus of actinobacteria that produces drugs like neomycin and chloramphenicol. Despite deriving many antibiotics already from Streptomyces, coul... Read More

Zika Virus in the USA

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

ASM Members Deliver a Landslide Endorsement for Governance Change - Part I

Change does not come easily to most organizations, let alone to one with more than a century of history. Indeed, twice before ASM tried—and failed—to change its governance structure. This time, ASM members embraced change, realizing that ASM must become more modern and more nimble in its decisio... Read More

Multivalent vaccines may help prevent future outbreaks

The Coalition for Epidemic Preparedness Innovation (CEPI) hopes to prevent future outbreaks by generating, testing, and storing vaccines before outbreaks occur. How do you design a vaccine before a prevailing serotype is determined? Read More

TWiV 424: FLERVergnügen

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.

Is it safe to go into the ocean? Standardizing molecular methods for water safety surveillance

Have you ever gone to the beach, ready for a day of sun and sand, only to find a warning sign? One of the most common reasons beaches close is due to the presence of coliform bacteria. These indicator bacteria, such as Escherichia coli, are used as markers for fecal waste, since their presence c... Read More

New tools to detect new virus

In fall 2015, a new human hepegivirus (HHpgV-1) was identified by using a novel, high throughput sequencing technique. Concerns were raised that this virus was found in blood to be used for transfusions, potentially passing on the infection. But without tools to test for its presence, there was ... Read More

False impressions in predatory publishing

Imitation may be the sincerest form of flattery, but it can also be the easiest way to make a buck. That’s the primary motivation for camouflaging within an already-established brand: Sunbucks, McDowell’s, and Mountain Lightening all rely on brand recognition – of a brand that isn’t their own. W...
