These mutations are epidemiologically linked with antibiotic resistance, failure to eradicate infection, later stages of disease, or worsened lung function, but conditions in the respiratory tract selecting for these mutations remain unclear. Chronic rhinosinusitis (CRS) is highly prevalent in CF and the sinuses are a primary colonization site that is hypothesized to support \u003Cem\u003EP. aeruginosa\u003C\/em\u003E dissemination into the lungs. My research in the Bomberger Lab examines the ecology and evolution of sinus \u003Cem\u003EP. aeruginosa\u003C\/em\u003E populations. We have identified at least 3 distinct evolutionary genetic routes by which \u003Cem\u003EP. aeruginosa\u003C\/em\u003E adaptively evolves to persist in the upper respiratory tract in CF CRS. Ongoing work is aimed at determining whether and how selective pressures in the sinuses may be therapeutically relieved in order to prevent or delay \u003Cem\u003EP. aeruginosa\u003C\/em\u003E pathoadaptation to the respiratory environment.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Invited Speaker Summer Seminar Series"}],"uid":"35021","created_gmt":"2020-07-26 22:17:18","changed_gmt":"2020-07-27 23:59:25","author":"mavdonina3","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2020-07-27T16:00:00-04:00","event_time_end":"2020-07-27T17:00:00-04:00","event_time_end_last":"2020-07-27T17:00:00-04:00","gmt_time_start":"2020-07-27 20:00:00","gmt_time_end":"2020-07-27 21:00:00","gmt_time_end_last":"2020-07-27 21:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
