ASM Live Denver 2013

Be part of the studio audience for the American Society for Microbiology 2013 General Meeting's live internet talk show, ASM Live. Host Stanley Maloy, Ph.D., Professor of Microbiology and Dean of the College of Sciences, San Diego State University, will discuss the latest science at the meeting with a variety of guest researchers and will take questions from the audience and the internet.

Tapings will take place in Room 102 in the Colorado Convention Center and meeting registrants are encouraged to attend. You can watch ASM Live below and topics will be archived immediately on YouTube and MicrobeWorld for future viewing.

(To ask a question please post it in the chat or tweet it using the hash tag #asmlive. ASM Live is now mobile friendly.)


Please note: The following schedule is preliminary and subject to change. Participants and more detail for each conference will be posted soon. All participants are invited, not confirmed. All times are listed as Mountain Daylight Time. All events take place in Room 102 at Colrado Convention Center in Denver. 

Sunday, May 19

11:00 a.m. MDT - ASM Live  Antibiotic Compound from Wasp Venom
Watch Now! 

Antimicrobial peptides (AMPs) are part of the innate immune system that is widely distributed in nature, acting as a defense mechanism against invading microorganisms. AMPs have potent antimicrobial activity against a range of microorganisms including fungi, bacteria and viruses. In view of growing multidrug resistance, AMPs are increasingly being viewed as potential therapeutic agents with a novel mechanism of action. Mastoparan, a natural, highly positively charged AMP derived from the venom of wasps, is a highly effective antibacterial agent and is therefore a potential alternative to currently antibiotics.  Participants will discuss the potential of this new compound as well as the increasing understanding of the role antibiotics play in nature.

12:00 p.m. MDT - ASM Live  Good Cholesterol: Part of Innate Immunity?
Watch Now!

Trypanosome Lytic Factor (TLF) has emerged as a novel arm of innate immunity that is only present in humans and select non-human primates. TLF was originally discovered in human blood as a minor form of High-density lipoprotein (HDL), also known as a good cholesterol, that rapidly kills the African trypanosome, Trypanosoma brucei, thereby making humans resistant to infection.  Participants will discuss this finding as well as how understanding these mechanism will provide insights as to other pathogens that TLF should kill, as well as offer potential avenues to therapeutically augment or mimic TLF action.

1:00 p.m. MDT – ASM Live – The Role of the Gut Microbiome in Colon Cancer
Watch Now!

Could the bacterial populations in your intestines predict the onset of colon cancer?  Participants will discuss new research in mouse models that suggests a major shift in microbial population dynamic prior to the onset of tumors as well as the general promise microbiome research holds for the diagnosis and potential management of other diseases.

  • David Relman, Stanford University, Palo Alto, CA, United States

3:00 p.m. MDT - This Week in Virology
Watch Now! 

Participate in a live streaming video episode of This Week in Virology (TWiV), a podcast about viruses. Started in September 2008 by Vincent Racaniello, a Higgins Professor in the Department of Microbiology and Immunology at Columbia University, the goal of the show is to have an accessible discussion about viruses that anyone can understand and enjoy. In Denver, Racaniello, co-host Kathy Spindler, and guests will be highlighting and commenting on some of the most exciting virology at the conference. Audience participation is encouraged so please feel free to ask any questions or offer your comments up to discussion.

10:00 a.m. MDT – ASM Live – New Methods for Norovirus Detection/Prevention
Watch Now! 

Norovirus is the most common cause of acute gastroenteritis in the United States. Each year, it causes about 21 million illnesses and contributes to about 70,000 hospitalizations and 800 deaths. Norovirus is also the most common cause of foodborne-disease outbreaks in the United States. Researchers have developed a method to detect human norovirus in produce and other environmental samples with low virus concentrations, contributing to our understanding of routes of produce contamination on farms.  Dr. Lee-Ann Jaykus will discuss this development as well as the importance of biotechnology to food safety and public health.

  • Lee-Ann Jaykus, North Carolina State University, Raleigh, NC, United States

11:00 a.m. MDT - ASM Live  The Merlot Microbiome
Watch Now!

Plants associated bacteria play a key role in host productivity and health. These bacteria are phylogenetically diverse and form interactions considered neutral, beneficial or detrimental. A better understanding of these interactions will have a direct impact in agriculture by promoting sustainable practices. Researchers are currently hard at work studying the bacteria associated with one agriculturally important plant: Grapevines that produce the varietal Merlot.   Participants will discuss their current findings. 

12:00 p.m. MDT - ASM Live  The Effects of Fracking on the Microbial Ecology of Groundwater
Watch Now!

Hydraulic fracturing, or “fracking”, is the process of drilling and injecting fluid into the ground at a high pressure in order to fracture shale rocks to release natural gas inside.  What effect does this process have on the microorganisms that naturally exist in the water in this process?

3:00 p.m. MDT - This Week in Microbiology
Watch Now! 

Participate in a live streaming video episode of This Week in Microbiology (TWiM), a podcast about unseen life on Earth.  Following in the path of his successful shows 'This Week in Virology' (TWiV) and 'This Week in Parasitism' (TWiP), Vincent Racaniello and guests produce an informal yet informative conversation about microbes which is accessible to everyone, no matter what their science background. In Denver, Racaniello, co-host Moselio Schaechter, Michael Schmidt, and guests will be highlighting and commenting on some of the most exciting microbiology at the conference. Audience participation is encouraged so please feel free to ask any questions or offer your comments up to discussion.


Tuesday May 21


9:00 a.m. MDT - ASM Live - Update on H7N9: Should We Be Concerned?
Watch Now!

The emergence of human infections with avian influenza viruses (H7N9 and H5N1) have raised concerns about the virus gaining the ability to spread person-to-person, potentially causing a deadly pandemic. So far the number of human cases has been limited but the mortality rates have been high.  In response to this public health threat the ASM’s Public and Scientific Affairs Board (PSAB) has convened a special-latebreaking session to discuss the molecular biology of these viruses and the likelihood of human to human transmission of these viruses. In advance of this session, speakers will participate in an ASM Live session to discuss their presentations and take questions from the viewing audience. 

10:00 a.m. MDT – ASM Live – The Microbiome of the Sky: Role for Microbes in Cloud Formation?
Watch Now!

Whether the microorganisms routinely inhabit the upper troposphere – perhaps living on carbon compounds also found there – or whether they were simply lofted there from the Earth’s surface isn’t yet known. Airborne microbes are of interest to atmospheric scientists, because they could play a role in forming ice that may impact weather and climate, and long-distance transport of the bacteria could also be of interest for disease transmission models.  Participants will discuss their research characterizing the bacteria present at different altitudes in the troposphere and genetic mechanisms by which microbial cells could reach and remain at high altitudes in the atmosphere and initiate the formation of water droplets or ice crystals, which is important for cloud formation.
