James R. Johnson, M.D. is a Professor of Medicine and Director of the Infectious Diseases Fellowship Program and the VA Molecular Epidemiology Unit. Dr. Johnson received his training in internal medicine and infectious diseases at the University of Washington in Seattle. His research interests include: 1) molecular pathogenesis of urinary tract infections, with an emphasis on the virulence properties, ecology, and phylogenetic aspects of uropathogenic E. coli, 2) molecular epidemiology of antibiotic resistance in E. coli, and 3) virulence factors and molecular epidemiology of enterococci, including VRE.
