New coatings to apply to soft cheese have been developed by researchers. These coatings are totally edible and have an antimicrobial capacity, which increases the lifespan of the cheese. These films incorporate oregano and rosemary essential oils as antimicrobial agents, and chitosan, a by-produ... Read More
Newly tenured biologist Jeroen Saeij wants to know what makes Toxoplasma gondii so unpredictable.
Toxoplasma gondii is a common parasite often spread by cats. Most people who are infected in Europe or North America show no symptoms at all, and only a few suffer from encephalitis or ocular tox... Read More
Nora Besansky, O’Hara Professor of Biological Sciences at the University of Notre Dame and a member of the University’s Eck Institute for Global Health, has led an international team of scientists in sequencing the genomes of 16 Anopheles mosquito species from around the world.
Anopheles mosq... Read More
When the World Health Organization recently named blood transfusions from Ebola survivors as its priority experimental therapy for the disease ravaging west Africa there was only one major problem: no data indicating that such transfusions work. Blood plasma from survivors contains antibodies th... Read More
Although it is far from unanimous, the great majority of phages studied so far package their genomes for intercellular space travel as linear chromosomes. Why linear rather than circular? Packaging convenience, for one thing. Many phages, including all of the tailed phages, package their chromos... Read More

Vincent, Alan, and Rich discuss how norovirus, an enteric virus, can replace the functions of the gut microbiome.
Microvores: A Game of Parasites is a microbial themed educational strategy game that has been funded on Kickstarter.com and has made the main-stream news! Read More
Though horizontal gene transfer (HGT) is widespread, genes and taxa experience biased rates of transferability. Curiously, independent transmission of homologous DNA to archaea, bacteria, eukaryotes, and viruses is extremely rare and often defies ecological and functional explanations. Here, we ... Read More
Have you thanked a vulture today? It turns out that they're getting rid of an awful lot of dangerous bacteria for us. According to new research published Tuesday in Nature Communications, the vulture has a gut designed to kill off the bacteria that thrive on the carrion they crave. When they cho... Read More
When we talk about viruses, usually we focus on the suffering caused by Ebola, influenza and the like. But our bodies are home to trillions of viruses, and new research hints that some of them may actually be keeping us healthy.
“Viruses have gotten a bad rap,” said Ken Cadwell, an immunologi... Read More
A common ingredient in vegetable oils may help reduce infection with a bacterium that can cause stomach cancer and peptic ulcers, according to a study by UC San Diego scientists.
The ingredient, linolenic acid, killed the bacterium Helicobacter pylori in mice and reduced inflammation without ... Read More
A larger percentage of patients with human immunodeficiency virus (HIV) achieved normalization of CD4+ T-cell counts when they started antiretroviral therapy (ART) within 12 months of the estimated dates of seroconversion (EDS) rather than later, according to a report published online by JAMA In...

For many bacteria and parasites looking to get a load of the fresh nutritional bounty inside your body, the skin is the first and most important gatekeeper. Schistosomas, however, and burrow right on through. These waterborne blood flukes, responsible for 200 million total worldwide cases of Sch... Read More
It's a dog eat dog world, and bacteria have been living in it for a long time. It's of no surprise that bacteria have a sophisticated arsenal to compete with each other for valuable resources in the environment. In 2010, work led by University of Washington Department of Microbiology Associate P... Read More
Researchers have made great progress in recent years in the design and creation of biological circuits — systems that, like electronic circuits, can take a number of different inputs and deliver a particular kind of output. But while individual components of such biological circuits can have pre... Read More
This episode: Pathogenic and non-pathogenic microbes have different strategies for interacting with us, even when they have a common ancestor!

Sea stars are lovely marine invertebrates with a round central body connected to multiple radiating legs (photo credit). In the past year millions of sea stars in the west coast waters of North America have melted into piles of slime and ossicles. Sea star associated densovirus might be the caus... Read More
