MTS10 - Anthony Maurelli - Black Holes and Antivirulence Genes
world@flpradio.com (American Society for Microbiology)
Author: American Society for Microbiology
Tues, Nov 25, 2008
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
world@flpradio.com (American Society for Microbiology)
Author: American Society for Microbiology
Fri, Nov 21, 2008
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.
