My colleagues and I have been studying microbial altruism in\u0026nbsp;E.\u0026nbsp;coli. Altruism in this system involves a cell secreting a substance called beta-lactamase, which breaks down antibiotics, and protects not just the cell secreting this substance, but all cells in the general vicinity. We\u0027ve done experiments that show that producing beta-lactamase is expensive and cells that don\u0027t pay these costs-- cheaters cells --grow more quickly than cells that do (when no antibiotics are around). And yet, these secreting altruists coexist side by side with their cheating fellow cells. I\u0027ll talk about experiments that help us understand why, briefly touch on some computer simulations that model microbial altruism, and then discuss work we have done that extends microbial altruism and cheating to interspecific interactions between\u0026nbsp;E.\u0026nbsp;coli\u0026nbsp;and Salmonella cells.\u0026nbsp;\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Lee Dugatkin, University of Louisville"}],"uid":"27964","created_gmt":"2014-12-12 10:46:30","changed_gmt":"2017-04-13 21:20:56","author":"Jasmine Martin","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2015-01-29T10:00:00-05:00","event_time_end":"2015-01-29T10:00:00-05:00","event_time_end_last":"2015-01-29T10:00:00-05:00","gmt_time_start":"2015-01-29 15:00:00","gmt_time_end":"2015-01-29 15:00:00","gmt_time_end_last":"2015-01-29 15:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1275","name":"School of Biological Sciences"}],"categories":[],"keywords":[{"id":"112171","name":"Lee Dugatkin"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78751","name":"Undergraduate students"},{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"174045","name":"Graduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EIf you have questions about logistics or would like to set up an appointment with the speaker, please contact the School of Biology\u0027s administrative office at \u003Ca href=\u0022mailto:bio-admin@biology.gatech.edu\u0022\u003Ebio-admin@biology.gatech.edu\u003C\/a\u003E.\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
