Haroldo Toro, DVM, PhD

Haroldo Toro, professor of avian diseases in the Department of Pathobiology, received his DVM degree in 1983 from the University of Chile College of Veterinary Sciences. His DVM thesis on antigenic and pathogenic characterization of avian infectious bronchitis (IBV) field isolates was directed by Dr. H. Hidalgo in the Laboratory of Avian Pathology. In 1987, Dr. Toro received his PhD from the Institute of Avian Diseases of Justus-Liebig-University of Giessen, Germany, under the guidance of Prof. Dr. E. F. Kaleta. His thesis work on new methods for the differentiation of IBV achieved magna cum laude. In 1987, Dr. Toro started his academic carrier at the University of Chile College of Veterinary Sciences, in Santiago. Between 1987 and 2002 his research was mainly focused on (1) local immune responses against IBV; (2) chicken anemia virus and its association with other avian pathogens; and (3) diseases of free-living birds. During this period he taught Avian Diseases to veterinary students and guided numerous DVM theses. After 15-years at the University of Chile, he joined the faculty at Auburn University College of Veterinary Medicine in May, 2002.

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.
