Haroldo Toro, DVM, PhD

Haroldo Toro, Professor of Avian Diseases in the Department of Pathobiology at Auburn University, received his DVM degree in 1983 from the University of Chile and his PhD in 1987 from the Justus-Liebig-University of Giessen, Germany. Between 1987 and 2001 Dr Toro worked as a faculty member in the Laboratory of Avian Pathology at the University of Chile College of Veterinary Sciences. In May, 2002 he joined the faculty at Auburn University College of Veterinary Medicine. His research focuses on viral diseases of poultry with special emphasis on infectious bronchitis, chicken anemia and avian influenza. Dr. Toro has published more than 80 peer-reviewed articles in the field of avian diseases and is a member of the editorial board the of the Avian Diseases journal. In May 2013 he was awarded Alumni Professor by the Auburn Alumni Association.


Research Interests

My research incorporates pathological, epidemiological, etiological, and immunological aspects of viral diseases of avian species. My current research work focuses on (1) further understanding chicken anemia virus (CAV) and the interactions of CAV with other avian pathogens; (2) further understanding the role of infectious bronchitis virus in respiratory disease of commercial chickens, and (3) development of a vaccine against avian influenza virus. My laboratory of Avian Diseases includes in vivo and in vitro systems for evaluation of disease.
