For thousands of years, epidemics of contagious diseases were believed to be caused by the wrath of the gods, configuration of stars, or miasma. The association of specific microorganisms with disease came about as a consequence of the work of the German physician Robert Koch. He formulated a se... Read More
What do microbes have to do with beer? Everything! Because the master ingredient in beer is yeast – a microbe – and every step in the brewing process helps the yeast do its job better. A new freely-available report; "FAQ: If the Yeast Ain’t Happy, Ain’t Nobody Happy: The Microbiology of Beer" ex... Read More

Vincent visits the Rocky Mountain Laboratories in Hamilton, Montana and speaks with Marshall, Sonja, and Byron about their work on tick-born flaviviruses, innate immunity, and prion diseases.
This month we talked with Dr. Christine Salomon, Assistant Professor at the Center for Drug Design in the University of Minnesota. Dr. Salomon’s work intersects chemistry and microbial ecology in the hunt for interesting new natural products with far reaching potential applications. While much... Read More
The TWiPyzoites solve the case of the Uncommon Parasite, and discuss the role of eosinophils in promoting the growth of Trichinella in skeletal muscle.

Efforts to expunge micro-organisms from spacecraft assembly cleanrooms, and the spacecraft themselves, inadvertently select for the organisms that are often the most fit to survive long journeys in space. This has the risk of thwarting the goal of avoiding contaminating other celestial bodies, a... Read More
Here's an interesting essay published in PLoS Biology by Michael Emerman and Harmit S. Malik on paleovirology, a topic recently discussed by Welkin Johnson, on the Small Things Considered blog.

Warren C. Ruder of Virginia Polytechnic Institute and State University (Virginia Tech) in Blacksburg, Virginia talks with Jeff Fox about efforts to develop an electronic model system that incorporates a robot for a host and two sligh... Read More
How do one-celled parasites move from the salivary gland of a mosquito through a person's skin into red blood cells? What molecular mechanisms form the basis for this very important movement of the protozoa? A team of researchers headed by Dr. Friedrich Frischknecht, head of a research group at ... Read More

It is well known that virus populations display phenomenal diversity. Virus populations are dynamic distributions of nonidentical but related members called a quasispecies. This diversity is restricted in single cells, but is restored within two infectious cycles. Read More
