Influenza: Searching for Pandemic Origins.

Abstract

From a farming family of 13 children in New Zealand, I graduated with a Master of Science degree in microbiology from the University of Otago (Dunedin, Otago, New Zealand). I established the first veterinary virology laboratory at Wallaceville Animal Research Station. I subsequently completed my PhD degree at Australian National University (Canberra, Australia) and a postdoctoral fellowship at the University of Michigan (Ann Arbor, Michigan). While in New South Wales, Australia, a walk on a beach littered with dead mutton birds (shearwaters) with Dr. Graeme Laver led to the surveillance of influenza in seabirds on the Great Barrier Reef Islands and my lifelong search for the origin of pandemic influenza viruses. Subsequent studies established that (a) aquatic birds are a natural reservoir of influenza A viruses, (b) these viruses replicate primarily in cells lining the intestinal tract, (c) reassortment in nature can lead to novel pandemic influenza viruses, and (d) live bird markets are one place where transmission of influenza virus from animals to humans occurs.
