MWV Episode 67 - The Secret Language of Bacteria

No bacterium lives alone – it is constantly encountering members of its own species as well as other kinds of bacteria and diverse organisms like viruses, fungi, plants and animals. To navigate a complex world, microbes use chemical signals to sense and communicate with one another.

Filmed live on January 28th, 2013, at ASM's headquarters, catch a glimpse into the fascinating language of bacteria with discussions by Bonnie Bassler, Princeton University, and Steven Lindow, University of California, Berkley.

Dr. Bonnie Bassler, Princeton University

Bonnie Bassler Ph.D. is a Howard Hughes Medical Institute Investigator and the Squibb Professor of Molecular Biology at Princeton University. The research in her laboratory focuses on the molecular mechanisms that bacteria use for intercellular communication. This process is called quorum sensing. Bassler’s research is paving the way to the development of novel therapies for combating bacteria by disrupting quorum-sensing-mediated communication. Dr. Bassler was awarded a MacArthur Foundation Fellowship in 2002. She was elected to the American Academy of Microbiology in 2002 and made a fellow of the American Association for the Advancement of Science in 2004. Dr. Bassler was the President of the American Society for Microbiology in 2010-2011; she is currently the Chair of the American Academy of Microbiology Board of Governors. She is also a member of the National Science Board and was nominated to that position by President Barak Obama. The Board oversees the NSF and prioritizes the nation’s research and educational priorities in science, math and engineering.

Dr. Steven Lindow, University of California, Berkeley

Steven Lindow Ph.D. is a Professor at the University of California, Berkley where his research focuses on various aspects of the interaction of bacteria with the surface and interior of plants. Dr. Lindow’ s lab uses a variety of molecular and microscopy-based methods to study the ecology of bacterial epiphytes that live on the surface of plants as well as certain bacteria that are vascular pathogens of plants. They also study bacteria that live in and on plants that are fostered by consumption of the alkaloids produced by endophytic fungi. The longer-term goal of their research is to improve plants’ productivity by achieving control of plant diseases through altering the microbial communities in and on plants. Dr. Lindow is a member of the National Academy of Sciences, and was elected to fellowship in both the American Academy of Microbiology and the American Association for the Advancement of Science in 1999.

Curtis Suttle - Marine Virology (MWV66)

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.

MWV Episode 65 - Natalie Prystajecky: Norovirus

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.

MWV Episode 64 - Anne Tanner: Microbes of the Mouth

In episode 64 of MicrobeWorld Video, Dr. Stan Maloy talks with Anne Tanner Ph.D., BDS, MDCH (Hon.), Associate Professor at Harvard School of Dental Medicine about her research into dental caries and the oral microbiome. This episode was filmed at the American Association for the Advancement of Science Meeting in Vancouver, Canada on February 18th, 2012.

 

 

Anne's work with Streptococcus mutans, the leading know cause of Early Childhood Caries (ECC), has led to the discovery of a new bacterium, Scardovia Wiggsiae. This discovery was the result of using modern molecular techniques combined with traditional anaerobic culture methods perfected in the practice of  periodontology. Anne is now working with this new bacterium to see if it's a caries pathogen.

Anne discusses the role probiotics have played in the treatment and prevention of dental caries. She is optimistic that these good bacteria can be effective in the battle against harmful oral bacterium.

Finally, Anne talks about being one of only a few people who has more than one microbe (Prevotella Tannerae and Tannerella forsythia) named after her.

MWV Episode 63 - Forest Rohwer: Microbes of the ocean, coral reefs and the human lung

In episode 63 of MicrobeWorld Video, Dr. Stan Maloy talks with Forest Rohwer Ph.D., Professor of Biology, San Diego State University, about his research on the microbes of the ocean, coral reefs and the human lung. 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.

MWV Episode 61 - Richard Lenski - Evolution in a Flask

In episode 61 of MicrobeWorld Video, filmed at the American Association for the Advancement of Science Meeting in Vancouver, Canada on February 17th, 2012, Dr. Stan Maloy talks with Richard Lenski Ph.D., Hannah Professor of Microbial Ecology, Michigan State University, about his research into the evolution of bacteria and the new frontier of digital evolution.

 

Lenski's Long Term Evolution Experiment with E. coli has seen over 50,000 new generations since its inception in 1998. This has led to insights such as how viruses can evolve from types that don't infect humans to ones that do.

Lenski's work with E. coli has also led him into the digital world. Using computers, Lenski can achieve precise, rapid results by manipulating digital organisms. Software that evolves much like bacteria in the real world.

Lenski is optimistic about the future of evolution research. Applying the generalities that have resulted from his studies to any number of other microbial species. He also sees large potential in applying what he's learned to the study of antibiotic resistance and bioengery.

Ron Atlas: Publication of H5N1 Research (MWV57)

In episode 57 of MicrobeWorld Video, filmed at the American Association for the Advancement of Science Meeting in Vancouver, BC Canada on February 18, 2012, Dr. Stan Maloy talks with Ron Atlas Ph.D., Chair of ASM's Biodefense Committee and Professor of Biology, University of Louisville.

Stan and Ron discuss the recent recommendation by the National Science Advisory Board for Biosecurity (NSABB) to withhold some of the key data regarding transmissibility from recent research on the H5N1 virus.

Ron explains how the NSABB was created and the role they play together with the American Society for Microbiology in attempting to establish a set of guidelines used to safeguard the scientific knowledge base from being misused.

Ron discusses the need for this research to emerge from it's current moratorium and continue in order to remain a step ahead of the virus in an attempt to be alerted to possible future pandemics.
