Dr. James E. Miller has been a member of the faculty since 1984; he was appointed full Professor in 1995 and was Acting Head of the previous Department of Epidemiology and Community Health (1999-2001). He is author and/or coauthor of over 70 refereed journal articles, numerous technical/report papers, proceedings papers, and abstracts, and three book chapters. He is a research collaborator with numerous national and international organizations including Utah State University (Logan, UT), the University of Georgia (Athens, GA), Virginia Tech University (Blacksburg, VA), Fort Valley State University (Fort Valley, GA), USDA ARS, Booneville, AR, Disney’s Animal Kingdom, San Diego Wild Animal Park, Busch Gardens Tampa, Audubon Zoo, BRECs Baton Rouge Zoo, the International Livestock Research Institute (Nairobi, Kenya), the Roslin Institute (Edinburgh, Scotland), the University of Otego (Dunnedin, NZ), the Moredun Research Institute (Edinburgh, Scotland) and the Danish Centre for Experimental Parasitology (Copenhagen, Denmark). He is affiliated with several professional organizations and is currently participating on 2 USDA National Projects: 1) Cattle/Sheep Animal Genome Technical Committee, National Animal Genome Research Program, National Research Support Program (NRSP-8), Sheep Committee Secretary (1999) and Chair (2000), and 2) Genetic (Co)Variance of Parasite Resistance, Temperament, and Production Traits of Traditional and Non-Bos indicus Tropically Adapted Breeds. He is a co-founder of the Southern Consortium for Small Ruminant Parasite Control. The Consortium’s primary purpose is to evaluate and promote alternative non-chemical methods for controlling nematode parasites. His teaching assignments include several professional and graduate courses in the School of Veterinary Medicine and undergraduate courses in the Department of Animal Science.
Research Interests
Dr. Miller is the principal investigator for several competitive and industry-supported grants dealing with the epidemiology, control, and genetics of ruminant nematode parasitism. His research program focuses on improving ruminant production using an integrated approach to controlling parasites. His area of special expertise is small ruminant gastrointestinal nematode parasitism, which is the most serious constraint affecting production world-wide. Economic losses are caused by decreased production, costs of prophylaxis, costs of treatment, and the death of infected animals. Anthelmintic resistance in nematode populations (specifically affecting small ruminants) threatens the success of treatment programs. Dr. Miller's research is directed at developing alternative strategies for control.
His current research program is two-fold: 1) To determine why, and/or how, Gulf Coast Native (Native) sheep are relatively more resistant to gastrointestinal nematode infection than Suffolk sheep, and 2) To evaluate alternative (non-chemical) approaches for protection against nematode infection. In 1), his lab is evaluating segregation of resistance leading to identification of closely linked genetic microsatellite markers associated with resistance using an F2 reference family approach. Such genetic markers can then be used for selection purpose and for fine mapping of the quantitative trait loci (QTL). They are also characterizing differences in the host immune response (Th1 vs. Th2) that might account for resistance. In 2), they are evaluating nematode-trapping fungi, condensed tannin-containing plants, copper wire particles and vaccination protocols in conjunction with strategic use of anthelmintics for use in integrated control programs.
