    In 2011, the NIH Clinical Center had a cluster of infections of a pathogen that tops the CDC's list of urgent threats: antibiotic-resistant Klebsiella pneumoniae. This bacteria, which can cause bloodstream and other infections, has recently developed resistance to the class of antibiotics known as carbapenems. The outbreak at NIH started with a single infected patient who was discharged weeks before any other cases were detected. This story of antibiotic-resistant infections is becoming more common around the world, and is especially dangerous in hospitals. Dr. Julie Segre, a senior investigator at the National Human Genome Research Institute, discuses how the outbreak was traced using state-of-the-art DNA sequencing.

    ASM's Cultures magazine traveled to Colombia to speak with and film the researchers behind an innovative biotechnology project that is producing exciting results. The international Swiss – Colombian collaborative research team from the University of Lausanne – Switzerland, the Universidad Nacional de Colombia, and the Universidad de la Salle – Utopia campus has been working to create and test novel strains of arbuscular mycorrhizal fungi (AMF) to improve cassava production. AMF forms symbiotic relationships with the majority of the world’s plant species, including cassava and other major food security crops. By colonizing internal structures within the plant and extending its root system, AMF transports nutrients such as phosphate to the plants from inaccessible areas and sources in the soil. In exchange, the plant provides carbon to AMF species that have colonized the plant. The research team’s studies show that, with the inoculation of certain AMF strains, only half of the necessary phosphate amendments are needed in nutrient-poor tropical soil to produce an equal or greater amount of cassava yield. On a large scale, this technology could potentially provide a more sustainable approach to resource management, allow small shareholder farmers to reduce their input costs, and help create a food secure future for many. In fact, an early model for this success is already being realized by graduates of the Utopia campus, all of whom come from conflict and post-conflict zones. By utilizing their education in agronomy in conjunction with this technology, they can begin rebuilding their home communities while ensuring a food secure future for Colombia and the greater global community.

    Have you ever wondered why mozzarella bubbling and stretching between pizza slices is so different from the earthy flavors of blue-veined gorgonzola? The diversity of cheeses we love are created by encouraging and manipulating the growth of specific microbes. The American Society for Microbiology is excited to explore and celebrate the roles microbes play in the production of a variety of cheeses - from milk-gathering to cheese aging. This video was streamed live from ASM headquarters in Washington, D.C., on June 10, 2014, as part of its Microbes After Hours program. Presenter's include: Dr. Rachel Dutton, Harvard UniversityAfter receiving her PhD in Microbiology from Harvard Medical School, Rachel Dutton was awarded a Bauer fellowship at Harvard University to start an independent research group. She combined her passions of microbiology and food into a research program that has the goal of using cheese as a way to understand microbial ecosystems. Cheese is home to a fascinating assortment of microbes; from bacteria, yeasts and molds, to microscopic mites. Work in the Dutton lab involves studying the microbial diversity of cheeses from around the world, and looking at how cheese microbes interact with each other to form communities. Rachel has been a speaker at events such as the World Science Festival, and regularly gives classes to the general public on the science of cheese and other fermented foods. Research from the Dutton lab has been featured in Lucky Peach Magazine, The Mind of a Chef TV series on PBS, EdibleBoston, the Boston Globe, NPR, and the New York Times. Mateo Kehler, Jasper Hill FarmsMateo Kehler started Jasper Hill Farm with his brother Andy in 2003 where they produce a wide range of cheeses from the milk of their herd of 45 Ayrshire cows. In 2008 they started a new venture, the Cellars at Jasper Hill, a 22,000 square foot underground cheese ripening facility, to lower the barriers to entry for new cheesemakers by maturing, marketing and selling cheeses, managing logistics and administration and providing technical support to local producers. The Cellars at Jasper Hill is committed to developing economic mechanisms to keep the working landscape in Vermont's Northeast Kingdom working, and delivering deliciousness is a core and principle component in this effort. Mateo lives on the farm in Greensboro, VT with his wife Angie and children Reed and Zola.

    Rob Knight studies the diversity of microbial communities. For every person, microbes outnumber human cells by a factor of ten. Rob has found that this large population of microbes differs based on which part of your body they inhabit (head, hands, gut, etc.). These same microbes vary widely in type from person to person. Unlike the human genome which is 99.9% alike from person to person, people are 80 to 90% different in their microbial make up. Rob shares what the microbiome project as been able to learn about these variances among the microbes on and in us and how probiotic therapies might be developed to help treat specific issues related to a person's microbiome. Ecosystem level therapies such as stool transplants that recolonize a person's gut microbiome have shown promising results. The question then is, do we know enough about therapies that alter someone's microbial flora to avoid the same kind of problems that non-native species have wreaked on other natural environments? Rob also discusses a project he's been working on in Bangladesh which brings powerful computing analysis to scientists who don't have the resources to utilize advanced computing in their research.

    Sheldon Campbell sings about microbiology. Dr. Campbell teaches microbiology at Yale School of Medicine and he uses music to enhance his lectures. He has one song for every block of lectures he gives on a major topic. Songs he's written include a song about fungi, tick borne disease, tuberculosis and one that reviews all of microbiology in eight minutes. Dr. Campbell hasn't done any testing to see his songs are more effective at getting his message across but he does get the occasional student who says they remembered something on a test because of his music. And the students seem to enjoy it, if not at first, by the end of the course they're singing along. Dr. Campbell uses his love of music because he believes that if you bring something of yourself into your teaching you'll be a much more engaging and effective teacher.

Professor zur Hausen talks about the beginnings of his work on the human papilloma virus (HPV) starting in 1972 with a group he setup to look at the "isolation and characterization of the viruses in genital warts." This group would lead to the discovery of HPV 16 and 18 (the leading cause of cervical cancer) amongst many other types. The discovery of these two particular strains of HPV led to insights into the cancer causing properties of HPV which would result in the production of the HPV vaccine. Vincent and Professor zur Hausen also discuss other virus related cancers including the possibility that colon cancer is a product of a virus and the application of the HPV vaccine to males as well as females.

    2012 saw a surge of West Nile Virus infections, particularly in the central United States. What exactly is West Nile Virus and why do outbreaks occur? Join us at ASM headquarters to learn more about the biology of this fascinating virus - how it moves between hosts, how the disease is diagnosed and treated, and how outbreaks can potentially be prevented. West Nile virus was first detected in North America until 1999 when an outbreak occurred in New York City. In the next five years, West Nile virus swept across the continent, reaching the Pacific shore in 2004. Like other Flaviviruses, West Nile is an "arthropod-borne virus" or "arbovirus". Its transmission and the completion of its life cycle critically depends on the feeding activities of mosquitos, who transmit the virus as they feed on the blood of infected animals Despite the incidence of infection among humans, however, Homo sapiens are actually dead-end hosts for the West Nile virus. Indeed, birds are the primary amplifying hosts and their migratory patterns are thought to have promoted the rapid spread of the virus to new habitats.  Guest speakers include: Dr. Lyle Petersen  Lyle R. Petersen, M.D., M.P.H., has served as the director of the Division of Vector-Borne Diseases since 2004. Dr. Petersen began his training at the University of California, San Diego where he received an undergraduate degree in biology.

    Richard Cogdell is the Director of the Institute for Molecular Cell and Systems Biology at the University of Glasglow, Scotland. Richard was led to a career in studying bacterial photosynthesis by a desire to learn and understand basic photosynthesis, he "wanted to know how natured worked." In 1995, Richard's research group, in collaboration with others, used protein crystallography to determine the three dimensional structure of a light-harvesting complex from the purple bacterium, Rhodospsedomas acidophilia. This breakthrough led to two key elements in the understanding of bacterial photosynthesis. One, once you have established the structure you can understand its function. Two, this view of a light-harvesting complex attracted an interdisciplinary group of scientists from the fields such as chemistry, physics, mathematics and biology. Richard's current challenge is to take the process of photosynthesis (using solar energy to make a fuel) and apply it to the world's energy needs in a sustainable manner. To do this, Richard says "you must break photosynthesis down to it's four most basics steps", absorb solar energy, concentrate it, break it apart and make a fuel. These are the steps that must be duplicated if they are going to be successful at creating sustainable, renewable energy. The first two steps, says Cogdell, are like a solar battery (easy to recreate). The hard part is finding ways to use renewable energy to drive the chemistry. That's the process Richard spends most of his time working on and he uses the concept of an artificial leaf to help explain this complex process to the public. According to Cogdell, if the current rate of investment continues, it will be approximately five to six years before we see a small pilot system that demonstrates the feasibility of the process. Richard emphasizes that if mankind wants to survive, we must find a way to convert solar energy into fuel because when fossil fuels run out so do we.

    Constructed in 2009 in the highly populated South End neighborhood of Boston, Massachusetts, the National Emerging Infectious Diseases Laboratories (NEIDL) facility contains labs that operate at biosafety levels 2, 3 and 4. Due to its location the NEIDL has faced a raft of legal and regulatory hurdles that have prevented BSL-3 and BSL-4 labs from becoming functional. “Threading the NEIDL,” is a 1-hour documentary produced by MicrobeWorld (the public outreach website by the American Society for Microbiology) and narrated by Vincent Racaniello, Ph.D., Higgins Professor of Microbiology & Immunology at Columbia University, which explores how the NEIDL is secured from unauthorized entry, what's like to wear a BSL-4 level safety suit, how the facility is constructed to make it safe, and how workers carry out experiments with highly dangerous viruses such as Ebola virus and Lassa virus without jeopardizing their health or that of the surrounding community. This is a never before seen look at how one of America's state of the art biodefense research facilities operates and the security measures put in place to keep it safe, even in the heart of a major urban center. This documentary was filmed in conjunction with Boston University School of Medicine and the popular science podcast This Week in Virology, which is also hosted by Vincent Racaniello.

    In MicrobeWorld Video episode 66 Dr. Stan Maloy talks with Curtis Suttle, Professor of Earth & Ocean Sciences, Microbiology & Immunology, and Botany, and Associate Dean of Science University of British Columbia.  Dr. Suttle is one of the World's leading marine virologists, and is among a small group of researchers that is credited with launching the field of marine virology. Dr. Maloy talks with Dr. Suttle about the incredible diversity of the ocean's microscopic inhabitants that have long been overlooked.  The oceans are mostly microbial, 98% by weight, which means most of what is going on in the oceans is unseen and until recently largely unknown. Dr. Suttle explains the large role that ocean viruses play in keeping our planet alive. In fact, Dr. Suttle points out that viruses do more to create life than take it away. If you were to take the viruses out of the ocean much of the planet's life-cycle would stop, there would be no more photosynthesis. Viral replication drives the major bio-geochemical cycles on Earth.  Dr. Suttle also discusses transposons, "the world's first immune system," phage and using genomic sequencing to do ecology outside of the lab environment.  This episode was recorded at the American Association for the Advancement of Science Meeting in Vancouver, British Columbia on February 17, 2012.

    In episode 65 of MicrobeWorld Video, Dr. Stan Maloy talks with Natalie Prystajecky Ph.D., Environmental Public Health Microbiologist, BCCDC Public Health Microbiology and Reference Laboratory, about her work with norovirus. This episode was filmed at the American Association for the Advancement of Science Meeting in Vancouver, Canada on February 16th, 2012.   Norovirus is the leading cause of acute gastroenteritis in the world. In the U.S. norovirus accounts for up to sixty percent of all gastrointestinal related illness representing approximately twenty-three million cases annually.    Because norovius is easily transmitted from person to person, outbreaks such as the kind that occur on cruise ships, airplanes and universities are common news. New technologies such as real-time PCR have led to more effective techniques for diagnosing the virus and thus the appearance of more cases of norovirus.   However, according to Prystajecky, cases of norovirus have been decreasing since their peak in 2003. The number of acute illnesses related to norovirus rise when new strains emerge such as the GII.4 strain in late 2009.   Beyond person to person transmission, norovirus has the ability to spread via food and waterborne sources. In every case using proper food handling techniques, being aware of your food and water source and proper hand washing (soap and water) are all effective measures for avoiding the virus.    There are no current vaccines against norovirus.

This episode was filmed at the American Association for the Advancement of Science Meeting in Vancouver, Canada on February 18th, 2012. Viruses make up a large portion of the world's oceans, with over ten million per milliliter of seawater. Rohwer's interest in better understanding these viruses led him to becoming an expert in marine virology and a founder of the field of viral metagenomics.  Forest discovered that these viruses are very good at controlling the number and type of bacteria in the ocean and through the process of gene transfer possess the potential to change marine bacteria into human pathogens.  Among Forest's other interests are coral reefs. He has studied the link between humans inhabiting the land around coral reefs and the decaying health of the corresponding coral.  Forest also studies cystic fibrosis, a disease of the human lung, which mimics what he sees going on with the health of coral reefs. Rohwer explains how his work across many different scientific disciplines has helped his research interests broaden while leading to new discoveries unlikely to have been made without the knowledge and tools of other scientific fields.
