Research Synopsis

Dr. Bakken is the author of more than 60 scientific publications and has authored half a dozen book chapters on various infectious disease topics. He has been an active researcher during most of his career and in 1994 described the first 12 cases of a new infectious tick-transmitted disease named human granulocytic ehrlichiosis (HGE, now named human granulocytic anaplasmosis or HGA). HGA is now a reportable illness and currently ranks as the second most common tick-borne infection with more than 4000 cases reported in the United States. Cases of HGA have also been described in 13 foreign countries. During the last 15 years Dr. Bakken has conducted collaborative research on treatment alternatives for patients with relapsing Clostridium difficile diarrhea (RCDAD). He was the senior author on an article published in Clinical Infectious Diseases in 2003 that reported on the benefits of fecal biotherapy for RCDAD.
