This forum brings together clinicians and scientists from around the world to engage in presentations, dialogue, and interaction related to the clinical and microbiological aspects of anaerobic bacteriology. The Congress will explore the role of anaerobes in both health and disease, while addressing traditional and emerging technologies for identification and diagnosis. ANAEROBE 2018 again illustrates the international interest in the field of anaerobic bacteriology: 171 abstracts were submitted for presentation, representing the work of over 600 scientists from nearly 30 countries. The Keynote Address will be given by MacArthur Foundation Fellow Sarkis Mazmanian, Ph.D. of the California Institute of Technology. Dr. Mazmanian will discuss the molecular mechanisms of the gut microbiome associated with inflammatory bowel disease. The Lifetime Achievement Award will be presented to Ellen Jo Baron, Ph.D. of Stanford University and Cepheid. Dr. Baron is being recognized for her outstanding career contributions to the fields on anaerobic bacteriology and infectious diseases. We would like to thank the members of the Organizing Committee and the Session Chairs for their assistance in formulating what promises to be another exciting program. We also would like to thank those from industry—both patrons and exhibitors listed on page v—for the financial support that makes this Congress possible, as well as grants from the Burroughs Welcome Fund, Merck, Sanofi-Pasteur, Pfizer, and the European Society of Clinical Microbiology and Infectious Diseases. In addition, we are grateful for our continued relationship with Anaerobe Systems for helping organize the Pre-Congress Workshop, Microbiology Educational Services for providing the continuing education accreditation for laboratory scientists, and to our Anaerobe journal for sponsorship of the Young Investigator’s Competition. Very special thanks goes to Dr. Ronald and Pamela Goldman, who again have done an exemplary job in bringing this meeting together. Finally, please take the opportunity to explore and experience the glitz, glamour, and gaudiness of America’s entertainment capital! Our hope is that ANAEROBE 2018 serves to foster stimulating discussions, as well as cultivate personal relationships that continue to invigorate the entire field beyond the timeframe of this Congress. Jeanne Marrazzo, M.D. ASA President iii ANAEROBE 2018 About the Society ABOUT THE ANAEROBE SOCIETY Founded in 1992, the Anaerobe Society of the Americas, a non-profit foundation, serves as a forum for those interested in anaerobes, anaerobic infections, and related matters. The Society aims: (1) to stimulate interest in anaerobes and to encourage interchange among anaerobists from all disciplines, including medical, dental, veterinary, environmental, and basic sciences; (2) to bring together investigators, clinicians, and laboratory scientists interested in anaerobic infections for formal and informal meetings; (3) to review and assess new advances in the field; (4) to discuss areas of controversy; and (5) to mark future directions. There are four levels of membership: Doctoral, Non-Doctoral, Verified Student, and Retired. Details and application form are available on our web site: www. anaerobe.org.

Dr. Mazmanian is the Luis B. and Nelly Soux Professor of Microbiology in the Division of Biology & Biological Engineering at the California Institute of Technology and an Investigator of the Heritage Medical Research Institute. He began his college career at the University of California, Los Angeles (UCLA) with the intent of becoming an English major, but after exposure to the microscopic world in the biology lab, he “never looked back.” He earned his Ph.D. at UCLA in 2002— under the tutelage of Dr. Olaf Schneewind— Photo: John D. & Catherine T. MacArthur Foundation Photo: John D. & Catherine T. focusing on the virulence factors related to Staphylococcus aureus. With a Helen Hay Whitney Postdoctoral Fellowship, his interests shifted to gut bacteria, joining the lab of Dr. Dennis Kasper at Harvard University to study Bacteroides fragilis. In 2006, he established his own lab at Cal Tech, where he has taken a broader look at the gut microbiome and potential link to Inflammatory Bowel Disease, Multiple Sclerosis, Parkinson’s disease, and Autism. Immunologic and neurologic imbalances underlie many diseases. The human body represents a scaffold upon which multitudes of commensal species build residence, creating a diverse ecosystem with members of five of the six kingdoms of life. Mechanisms that mediate the interdependent and complex interactions between the microbiome and animals, as well as their influences on human health, represent an exciting frontier of science and medicine. Our laboratory aims to discover how gut bacteria influence the development and function of the immune and nervous systems, with the goal of understanding mechanisms by which the microbiome contributes to the critical balance between health and disease. For his work, Dr. Mazmanian has received numerous honors, including the Burroughs Wellcome Fund’s Investigators in the Pathogenesis of Infectious Disease, (2011), a MacArthur Foundation “genius” grant (2013), and named by Discover Magazine as one of the “Best Brains in Science under 40.” He is a founder of two biotech companies and has or currently serves on the Scientific Advisory Board of over a dozen companies, academic centers, and not- for-profit foundations.
