Research

Dr. Dryden’s primary research focus has been the biology and control of fleas and ticks infesting dogs and cats. The "Flea and Tick Team" has conducted numerous laboratory and in-home evaluations of these products in Manhattan KS and Tampa FL and field studies at the Konza Prairie Biologic Station. 

A second area of research includes investigations into the epidemiology, diagnosis and control of gastrointestinal parasite in dogs and cats. Several studies have been completed including studies detailing the severity of parasite contamination of the environment, prevalence of parasite infestations in greyhounds in Kansas and development of anthelmintic resistance. A major focus of this research is evaluating fecal diagnostic techniques. Additionally, recent projects have included evaluating various diagnostic and treatment options for Giardiasis.

The combined research efforts have received both National and International recognition with over 135 published papers, 9 book chapters, and over 100 scientific presentations at national and international meetings. He has lectured in 22 countries, presenting > 850 invited seminars at national and international meetings.
