- MTS10 - Anthony Maurelli - Black Holes and Antivirulence Genes
(0mb)
Tues, 25 Nov 2008 12:43:04 -0500 Author: world@flpradio.com (American Society for Microbiology)
Tony Maurelli is a professor of microbiology and immunology in the F. Edward Hébert School of Medicine at the Uniformed Services University of the Health Sciences in Bethesda, Maryland. Dr. Maurelli?s major research interest lies in the genetics of bacterial pathogenesis ? the genetic nuts and bolts of how bacteria infect humans and make us sick. Dr. Maurelli?s work has uncovered ?antivirulence genes? in Shigella flexneri, a major cause of dysentery and food borne illness. This is an interesting concept: antivirulence genes undermine pathogenicity, so they must be broken or dropped from the genome for a bacterium to take good advantage of a host and cause disease. These genes are a hindrance, so to become an effective pathogen, Shigella must stop using them. In this interview, Dr. Merry Buckley talks with Dr. Maurelli about antivirulence genes, whether the naming system for bacteria should be fixed, and his favorite microbe. - MTS9 - Stanley Falkow - 21st Century Microbe Hunter (0mb)
Fri, 21 Nov 2008 09:43:04 -0500 Author: world@flpradio.com (American Society for Microbiology)
Stanley Falkow is a professor of Microbiology and Immunology at the Stanford School of Medicine. His research interests lie in bacterial pathogenesis ? how bacteria cause infection and disease ? and over the course of his career he has contributed fundamental discoveries to the field. Falkow received the Lasker prize this year for special achievement in medical science, and the Lasker Foundation calls him ?one of the great microbe hunters of all time?. Molecular techniques (methods of analysis that rely on bacterial DNA) are now widely used for infectious disease diagnosis, thanks in large part to Falkow, who was among the first to apply an understanding of genes and virulence determinants to analyzing patient samples. He has published extensively in areas ranging from antibiotic resistance to food borne illness to microarrays. In this interview, Dr. Merry Buckley talks with Dr. Falkow about his prescient concerns about the dangers of using antibiotics as growth promoters in livestock, why Salmonella is so good at making you sick, and why students who are interested in science should follow their passion. From this point forward, MicrobeWorld listeners should be caught up with the "Best of" Meet the Scientist to date. Episodes will now come out on the regular Meet the Scientist schedule which is approximately every two weeks. - MTS6 Bruce Rittmann - Microbes, Waste and Renewable Energy (0mb)
Thu, 20 Nov 2008 10:43:04 -0500 Author: world@flpradio.com (American Society for Microbiology)
Bruce Rittmann, the Director of the Center for Environmental Biotechnology at the Biodesign Institute of Arizona State, focuses his efforts on reclaiming contaminated water and producing renewable energy using microbes. He was elected to the National Academy of Engineering in 2004 and credited with pioneering development of biofilm fundamentals and contributing to their widespread use in the bioremediation of contaminated ecosystems. His research combines many disciplines of science, including engineering, microbiology, biochemistry, geochemistry and microbial ecology. Formerly with Northwestern University, Rittmann is also a leader in the development of the Membrane Biofilm Reactor, an approach that uses bacteria to destroy pollutants in water. The Membrane Biofilm Reactor is especially effective for removing perchlorate from drinking water, and it is being launched commercially. In this podcast, Merry Buckley talks with Dr. Rittmann about the biofilm reactor process, the electricity hiding in our wastewater, and how we may some day grow fuel on the roofs of buildings. - MTS4 David Relman - The Human Microbiome (0mb)
Wed, 19 Nov 2008 09:33:04 -0500 Author: world@flpradio.com (American Society for Microbiology)
David Relman is a Professor of Medicine and of Microbiology and Immunology at Stanford University, and his research program focuses on the human microbiome ? the microbial communities of bacteria, viruses, and other organisms that thrive on and in the human body. Since Louis Pasteur first deduced that microbes are to blame for infectious disease, doctors and scientists alike have mostly seen infection as warfare between a pathogen and the human body. Dr. Relman sees things a little differently. To him, the complex communities of microbes that line our skin, mouths, intestines, and other orifices are also involved in this battle, interacting with pathogens and with our bodies, and these interactions help determine how a fracas plays out.In this interview, Dr. Merry Buckley asks Dr. Relman about our personal ecosystems of microbes, whether we?ll ever be able to understand and predict what these communities do, and about the sometimes distressing effects of oral antibiotics on our guts. They also talked about whether being MTV?s Rock Doctor back in the 1990?s had an impact on his other professional pursuits. - MTS3 Ute Hentschel - Symbiotic Sea Sponges (0mb)
Tue, 18 Nov 2008 09:54:04 -0500 Author: world@flpradio.com (American Society for Microbiology)
Ute Hentshel is a professor of chemical ecology at the University of Würzburg in Germany. Her research focuses on characterizing the microbial communities associated with marine sponges, the diversity of these symbionts and their activities. On this episode, Dr. Merry Buckley talks with Ute Hentschel about her research on the microbes that live on and in sea sponges ? those squishy, colorful residents of coral reefs. Dr. Hentschel describes some of the utterly unique microbes that are only found in sponges, what those microbes get from living in a sponge hotel, and why it?s nice to have a study site in the Bahamas. - Important Info for MicrobeWorld Radio's Listeners (0mb)
