The topic for this week’s Friday Research Seminar Series will be microbiology and immunology. All faculty members and students are invited to attend.
Promiscuous Plasmids: How Sex Leads to the Success of Multidrug Resistant Bacterial Pathogens
University of Minnesota – St. Paul
Professor Timothy Johnson received his Ph.D. from North Dakota State University in 2004. He has received several awards for his research. Most recently being, in August 2010 the Bayer-Snoeyenbos New Investigator Award in Avian Research, AVMA/AAAP Annual Meeting. Prior to that he received the Brian Wilkins Young Investigator Award in Plasmid Biology, Meeting of the Plasmid Biology Society in Gdansk, Poland, 2008, the CRWAD Oral Presentation Award in Molecular Biology, Chicago, IL, 2004, Richard B. Rimler Memorial Paper Award, AVMA/AAAP Annual Meeting in Nashville, July 2002, and the Arnold S. Rosenwald Poster Award at the AVMA/AAAP Annual Meeting in Boston, July 2001.
Professor Johnson’s research focuses on the pathogenic mechanisms of bacteria causing disease in production animals. He is interested in better understanding the mechanisms of virulence and antimicrobial resistance employed by bacterial pathogens of poultry and swine. Much of his work has used genomics-based approaches to answer questions related to Salmonella enterica and Escherichia coli. It is because of the importance of large plasmids in the virulence and drug resistance mechanisms employed by these bacteria, that another area of interest is in the horizontal gene pool and the mechanisms and biology of horizontal gene transfer and host: chromosome regulatory “crosstalk” mechanisms.
