Research Interests:

Research in Dr. Nataro's lab is focused on the pathogenesis of E. coli and Shigella enteric infections. A major effort has been directed at understanding the pathogenesis, genomics, molecular epidemiology and diagnosis of enteroaggregative E. coli. Work has involved all other pathotypes of diarrheagenic E. coli as well. In the course of this work, the Nataro lab as discovered several new protein toxins and adherence factors in E. coli and Shigella
Another major thrust of research in the lab involves fundamental understanding of the autotransporter proteins, a class of proteins that secrete themselves the outer membrane of Gram-negative pathogens. These studies involve the biochemical and biophysical requirements of secretion as well as the roles of autotransporter toxins in enteric pathogenesis.
Dr. Nataro has used the technique of nuclear magnetic resonance to integrate structural biology into research on pathogenesis and vaccine development. Structures determined include the novel dispersin protein of enteroaggregative E. coli, an important virulence factor in this emerging pathogen. In addition, Dr. Nataro seeks to understand the effect of the immune response on the evolution of protein structure, a question of vital importance to future vaccine studies.
Dr. Nataro's lab is also involved in the development of vaccines against potential bioterror agents, especially plague.
