How do you identify an unknown microbe? If you’ve taken an introductory microbiology lab course in the past twenty years, chances are you were assigned an unknown bacterium that you had to identify through differential media and biochemical assays. Newer techniques like qPCR are being standardiz... Read More
This episode: Microscopic parasites of fish and worms actually came from jellyfish-like animals, after losing most of their genome!

Polio returns to Nigeria, Zika virus spreads in Miami, and virus infection of plants attracts bumblebees for pollination, from the virus gentlepeople at TWiV.
The TWiP troika solve the case of the Female from the Bronx, and reveal how feeding on different plants affects mosquito capacity to transmit malaria.
In some individuals, an influenza A virus infection can cause asymptomatic Staphylococcus aureus (S. aureus) to travel to the lungs where it can trigger severe, sometimes deadly, secondary pneumonia. S. aureus is one of the most common causes of secondary bacterial pneumonia in cases of seasonal... 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
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
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
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...

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
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
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, 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
This episode: Clostridium bacteria that infect potatoes can both kill competitors and tolerate oxygen, thanks to the pink compounds they produce!

Zika virus spreads in the USA, a Zika virus DNA vaccine goes into phase I trials, and how mosquito bites enhance virus replication and disease, from the friendly TWiFolk Vincent, Dickson, Alan, and Kathy.
Hosts: Read More
Vincent, Elio, and Michele present cell division by longitudinal scission in an insect symbiont, and thermally activated charge transport in microbial nanowires.
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
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
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
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
