One of the many reasons I am a member of the American Society for Microbiology is their dedication not only to excellent science, but science communication and public policy. “Microbes After Hours” is one of their fabulous science communication events. Since 2012, the ASM headquarters in Washington, DC has opened its doors to anyone interested in microbiology for talks, appetizers, and some microbially-fermented beverages. For those who can’t make it to DC, the talks are live streamed through ASM’s MicrobeWorld site. Speakers even take questions via email and twitter at the end of the talk. Fortunately, my mama-scientist, microbe-road trip friend, Robin Munroe, and I made it down in person to the January 28, 2016 Microbes After Hours that featured Dr. Marti Blaser talking about his research and book, Missing Microbes. Read more about his book in this previous post. I was thrilled to finally get my copy of his book signed! Below is our journey in photos compliments of Robin! She also live-tweeted our trip. For future adventures – follow me on Twitter @mostlymicrobes. Microbes After Hours Do you have questions about this or Dr. Blaser’s book? Anything else microbe related?

Missing Microbes and Increased Antibiotic Resistance
Dr. Martin Blaser’s book Missing Microbes details his observations and hypotheses on how overuse and misuse of antibiotics may be the source of modern non-communicable diseases, such as diabetes, asthma, and obesity. The maps of the U.S. colored with obesity and antibiotic prescriptions fit extremely well – and centered on my Southern homeland. Could it be that the obesity epidemic, diabetes, allergies, asthma, and other non-communicable diseases that are centered over the American South are not due to our preference for all things fried or sopped in butter and washed down with a swig of sweet tea? It’s not just due to sitting in front of screens too much. Certainly poor diet and little exercise don’t help. But could an over-use of antibiotics also be to blame? That was the hypothesis. Obesity Caused by Over Use of Antibiotics? Dr. Martin Blaser from NYU’s experimental research on mice demonstrated drastic changes in the different types of gut bacteria present before and after antibiotic use. More strikingly, when the antibiotic use was discontinued and the bacterial populations rebounded, the bacterial types that did come back were different metabolically. Antibiotics drastically effected the gut microbiome. Does antibiotic somehow set us on a path
