In northern Sweden, data from certain weather stations have shown that the snow season has been shortened by over two months in the last 30 years, which has huge effects on reindeer herding. Also, the climate sensitive human infection tularemia has tenfolded over the same period and is much more... Read More
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
Think the ISS is squeaky clean...think again! Bacteria like Staphylococcaceae and Enterobacteriaceae absolutely thrive in space stations! Read More
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
The TWiV gurus describe how to use an orthogonal translation system to produce infectious but replication-incompetent influenza vaccines.
A new study at The University of Texas Medical Branch in Galveston sheds light on how Ebola so effectively disables the human immune system.
Virologist Alex Bukreyev, UTMB professor and senior author of the study, said the research team engineered versions of the Ebola virus in order to study... Read More
Vaccines are like pathogen imposters - they mimic these 'bad guys' in order to provoke a response from our immune systems, remove the invader and begin the healing process.
One of the key components in a vaccine is an adjuvant, which serves to enhance our body's immune response to vaccination... Read More
Russian President Vladimir Putin claimed Wednesday his country had developed a vaccine for the Ebola virus which has killed thousands of people in west Africa.
But Putin, who is famed for his talent for headline-grabbing announcements, did not give any name for the vaccine, nor did he say how... Read More
Thanks to combination antiretroviral therapy, many people with HIV can be expected to live decades after being infected. Yet doctors have observed that these patients often show signs of premature aging. Now a study published April 21 in Molecular Cell has applied a highly accurate biomarker to ... Read More
The TWiMers discuss how changes in domestic laundering affect the removal of microorganisms, and assembly of a nucleus-like structure during viral replication in bacteria.
The TWiVeroos examine a reverse spillover of Newcastle disease virus vaccines into wild birds, and identification of a protein cell receptor for murine noroviruses.
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...

CORVALLIS, Ore. - A new analysis of the prehistoric origin of malaria suggests that it evolved in insects at least 100 million years ago, and the first vertebrate hosts of this disease were probably reptiles, which at that time would have included the dinosaurs. Read More
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
This episode: Some fungi change from making plants sick to being helpful to plants! How do plants react to them?

When I have to explain the organism classification to my students I usually use the one stablished by Woese in the 70s. In this classification, all living things are classified in six kingdoms, that are Eubacteria, Archeobacteria, Protista, Plantae, Fungi and Animalia. All of these groups evolve... 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
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
Unknown contaminant, possible Bacillus spp, seen on an old blood agar plate that had been inoculated with Strep bovis. The plate had been incubated at 37 degree's C for 24 hrs then held at room temp for a week. One colony was mucoid with a brain like appearance the other being mucoid and smoo... Read More
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
