Young Inventors Work On Secret Proteins To Thwart Antibiotic-Resistant Bacteria

Three young inventors and students at Stanford University are working to develop proteins that fight antibiotic resistant bacteria. They are optimistic they have found something that works. The proteins the team is developing attack "something that's essential to bacterial survival". But they wo... Read More

Table Top Swab III

Swab taken from the lab table top and incubated on TSA for 48 hrs, left at room temperature for 72 hrs then held at refrigerated temperature for a month. Pictured is an unknown isolated beige, mucoid colony. The center was raised and if the plate was tiled it would "drip". The edges of the colo... Read More

Maternal high-fat diet during pregnancy can affect baby's gut microbes

A new study by researchers at Baylor College of Medicine found that, "babies born to mothers who consumed a high-fat diet during pregnancy had a gut microbiome that was distinctly different from the one in babies of mothers on a non-high-fat diet".
Noteably, researchers found that, "the micro... Read More

New Model Sheds Light on Secondary Bacterial Pneumonia

Washington, DC – August 9, 2016 – For years, researchers have known that the bacteria Staphylococcus aureus (S. aureus) can trigger severe, sometimes deadly secondary bacterial pneumonia, in some people who are subsequently infected with influenza A virus, but scientists have not known exactly h...

Mcr-1 Gene Isolated from Human for the First Time in Brazil

Washington, DC – August 8, 2016 – For the first time in Brazil, a particular antibiotic resistance mechanism conferring resistance to the important antibiotic, colistin, has been detected in a human. It was in a strain of Escherichia coli that was isolated from a diabetic patient’s foot infectio... Read More

The cities of the future could be built by microbes

Today in Phys.org, Martyn Dade-Robertson explores the possibility of using microbes to produce natural cement. This process, called biomineralisation, was discovered deep under water off the coast of the Greek island of Zakynthos.
Future implications for biomineralisation include self-healing ... 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

Mosquito saliva enhances virus replication and disease

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

MWV 105 - Understanding the Pathogenesis of the Emerging Zika Virus

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

Hi TWiMers;

It is a nice late July evening here in Berkeley - 60F/15.5C - no fog, but we have had a bit less than usual summer fog this year.

Ran across this article which is fascinating  because it falls into the category of "what... Read More

Ferreting out an improved Ebola animal model

We’ve previously covered the importance of diagnostics in disease control and treatment. This is vital to controlling disease progression and transmission, but epidemiology studies can’t always show how a disease progresses or transmits. This is where scientists need a well-characterized animal ... Read More

ASM Urges Public Health Actions and Funding to Combat Zika Emergency

Washington, DC – August 5, 2016 – Current events linked to the Zika virus make aggressive public health actions and funding to combat this emerging infectious disease more crucial than ever. Newly reported Zika cases in Florida are the first examples of US infection spread by local mosquitos. ... Read More

And they're off! An overview of ASM resources on Olympic-related infectious disease reports

The opening ceremony for the Summer Olympics 2016 will be held this Friday, marking the onset of two weeks of competition between the world’s best athletes. The world has been focused on Brazil and its preparedness – not only for the infrastructure required for the games, but also for any potent... Read More

TED Talk: A forgotten Space Age technology could change how we grow food

Dr. Lisa Dyson is developing a way to sustainable produce agriculture using technology developed in the 1960's for space travel. Using carbon dioxide, hydrogen from water, and microbes called hydrogenotrophs, the "closed loop" carbon cycle can create carbon-rich crops. This technology has the po... Read More
