Animal disease researchers gather for annual meeting

Posted March 1, 2009
Some 480 people attended the 89th annual meeting of the Conference of Research Workers in Animal Diseases Dec. 7-9, 2008, in Chicago.
The conference was dedicated to Dr. Sidney A. Ewing of Stillwater, Okla., professor emeritus of the Department of Veterinary Pathobiology at the Oklahoma State University College of Veterinary Medicine.

A 1958 graduate of the University of Georgia College of Veterinary Medicine, Dr. Ewing has spent his career in the field of veterinary parasitology and is internationally known for his research on parasites transmitted from ticks to dogs.

Soon after receiving his doctorate from Oklahoma State, Dr. Ewing joined the faculty at Mississippi State University in 1965. Three years later, he returned to Oklahoma to head the Veterinary Parasitology and Public Health Department.

In 1972, Dr. Ewing was named dean of the University of Minnesota College of Veterinary Medicine. He returned to Oklahoma State in 1979 when he served as the Wendell H. and Nellie G. Krull Endowed Professor of Veterinary Parasitology and interim associate dean for academic affairs. He retired in 2003.

Life membership was awarded to Dr. Louis F. Archbald, Gainesville, Fla., and James A. Harp, PhD, Ames, Iowa.

Officers of CRWAD for 2009 are Bill Stich, PhD, Columbia, Mo., president; Dr. Eileen L. Thacker, Beltsville, Md., vice president; and Robert P. Ellis, PhD, Fort Collins, Colo., executive director.

The Association for Veterinary Epidemiology and Preventive Medicine named Dr. David W. Hird recipient of the 2008 Calvin W. Schwabe Award. Dr. Hird is professor emeritus at the University of California-Davis School of Veterinary Medicine, where he was a faculty member from 1980-2008.

The 1968 graduate of UC-Davis is widely regarded as a preeminent educator and leader in the fields of veterinary epidemiology and preventive medicine. Dr. Hird is a diplomate of the American College of Veterinary Preventive Medicine and a fellow in the American College of Epidemiology. A Fulbright Scholar, Dr. Hird has served as a consultant to the Agriculture Department and to several South American countries on disease surveillance and control programs for livestock.
