    • Adaptation and Evolution: The Life of an RNA Virus (MWV35)

      From the flu to HIV, RNA viruses challenge our immune systems like no other infectious agent on the planet. RNA viruses provide unique insights into the patterns and processes of evolutionary change in real time. The study of viral evolution is especially topical given the growing awareness that emerging and re-emerging diseases (most of which are caused by RNA viruses) represent a major threat to public health. How do RNA viruses adapt and change, and how do our bodies respond? Why are diseases like HIV so difficult to predict and contain? In episode 35 of MicrobeWorld Video, Eddie Holmes, professor in Biology at Pennsylvania State University leads a discussion before a live audience at Busboys & Poets in Washington, D.C. on the genetics and evolution of RNA viruses and how we can combat them.

          Allison Jack is one passionate young scientist who’s embracing the not-so-traveled path of "compost microbial ecology". Her focus is on compost and its ability to protect plants from diseases. This unusual field of study has already drawn teasing from amongst her mainstream agriculture science peers. Fresh from her graduate studies at Cornell University, and now a faculty member at Prescott College in Arizona, she seeks to map out the microbial mechanisms of plant protection through the use of compost and liquid compost extracts. Drawing from ancient and traditional farming techniques, Allison hopes to help conventional, organic and biodynamic growers achieve better results against plant diseases, without using synthetic pesticides. {Prescott College, 220 Grove Avenue, Prescott, AZ 86301}

                  Created for the general patient population at the GRU Department of Family Medicine, this animation is designed to prevent confusion, disappointment or hostility when a patient demands a prescription and the doctor refuses. It explains the difference between bacteria and viruses and thus the reason why antibiotics are not always the answer. The intent is to give a broader understanding of what antibiotic resistance is and why it is such a serious issue--from the global scale right down to your very own digestive tract.

                  • Antibiotics: Is a Strong Offense the Best Defense? (Part 1 of 3)

                    Will we become defenseless against bacteria? Will bacteria always find a way to infect and even kill us? The emergence of antibiotic resistant strains of bacteria poses an enormous problem around the world. Scientists believe that the overuse of antibiotics is increasing the appearance of these pathogens. In the US, increasing casualties resulting from drug resistant staphylococcus infections received wide media attention. While antibiotics only work on bacterial infections, many patients and doctors regard antibiotics as a front-line form of treating any type of infection. Antibiotics are often prescribed because the specific pathogen that is causing an illness is often difficult to determine. In some cases they are used as a preventative measure. But is this the best defense? Are there ways to beat bacteria at their own game? On September 18, 2008 at the Koshland Science Museum in Washington, D.C., Dr. Stuart Levy, professor of Molecular Biology and Microbiology at Tufts University School of Medicine and Dr. Linda Tollefson, Assistant Commissioner for Science at the U.S. Food and Drug Administration, discussed how to optimize antibiotic use and how to minimize the emergence of drug resistant pathogens. In part 1 of this 3 part video series, Dr. Levy discusses the basics of microbial pathogens, bacteria, and antibiotic resistance. And, Dr. Tollefson outlines the various types and classes of antibiotic drugs, approved uses, and current levels of effectiveness. Dr. Levy is Professor of Molecular Biology and Microbiology at Tufts University School of Medicine where he is the Director of the Center for Adaptation Genetics and Drug Resistance. He directs research on mechanisms of bacterial antibiotic resistance. Stuart Levy is also Staff Physician at the Tufts Medical Center and he also serves as the president of The International Alliance for the Prudent Use of Antibiotics. Dr. Tollefson is Assistant Commissioner for Science at the U.S. Food and Drug Administration (FDA). She previously served as Deputy Director of the Center for Veterinary Medicine (CVM), where she led CVM's efforts to implement a risk-based approach to address antimicrobial resistance, fulfilling a 2001 Congressional mandate, and was instrumental in the founding of the National Antimicrobial Resistance Monitoring System for Enteric Bacteria. Tollefson also served as Chief of Epidemiology in the Center for Food Safety and Applied Nutrition where she successfully investigated numerous outbreaks of food borne disease and served as liaison to the Centers for Disease Control and Prevention. Parts 2 and 3 will be published over the coming weeks. Please feel free to embed or distribute this video.

In part 2 of this 3 part video series, Dr. Levy discusses how antibiotic resistance develops, the development practices drug companies employ when producing antimicrobials, and how this process may change in the future. Dr. Tollefson outlines how the FDA is encouraging the development of antibiotics in an industry that is mostly focussed on manufacturing drugs for chronic illnesses.
