Description
Professor Roy C. Anderson, renowned professor of parasitology at the University of Guelph and world recognized researcher in the field of wildlife disease died August 27, 2001 in Guelph, Ontario. A Memorial Service held in the University of Guelph Arboretum, September 3, was widely attended by close friends, academic colleagues and former graduate students who gathered with Roy's family to celebrate his accomplishments and to relate how his enthusiasm for research and scientific rigor, his love for writing, his joie de vivre and continued friendship affected their lives. Above all, his sense of humour and mastery of storytelling that brought fun and laughter will be sorely missed. Roy always considered himself to be a member of the North American Moose Group and attended several annual meetings. "Moosers", more than any other scientific group, recognized the importance of one of his biggest discoveries--identifying the cause of the mysterious neurologic disease known for many years simply as "moose sickness". Like many great discoveries, his was part serendipity and part good detective work. While working one summer at the Lake Sasejewun Wildlife Research Station, Algonquin Park, Ontario, a colleague showed Roy a worm he'd found in the cranium of a white-tailed deer killed by a car. This introduction led Professor Anderson to a long and productive series of scientific studies progressively revealing the importance of this parasite, known as the "meningeal worm" or Parelaphostrongylus tenuis. First, he showed that P. tenuis has to develop in land snails or slugs before the larvae are infective. Deer picked up these land gastropods accidentally while feeding on herbs and grasses close to the ground. The larval worms are released from the tissue of the snail and penetrate the true stomach (abomasum). From there they migrate to the spinal cord and penetrate the nerve tissue where they mature. After about 90 days, they finally emerge from the spinal cord and spend the rest of their lives between the membranes (meninges) covering the brain. In this location they can reach a length of almost 9 cm! Virtually all deer in the east (but not western North America) have this worm and amazingly, none show any sign of disease. This was all new to science and very exciting, but more importantly, this knowledge led Roy to formulate an even more productive hypothesis.
