Veterinary Medicine Epidemiology (VM585). VM 585 is focused on major epidemiological concepts that influence the practice of veterinary medicine. Quality medicine is evidence-based and this class provides tools for evaluating information and guiding decisions regarding medical treatments and diagnostics. This class also serves as an introduction to concepts of population health essential to preventive, shelter, kennel, cattery, regulatory and livestock medicine.
My early scholarly output was based on research I completed at the University of Sydney, Australia.In a successful attempt to introduce a developed vaccine against bovine keratoconjunctivitis (pinkeye) into Australia, we isolatedMoraxella bovisstrains present within Australia for identification of fimbrial antigens, antimicrobial susceptibilities, and cytotoxin/hemolysin gene profiles.
During my time at Charles Sturt University, I began working with a team in Australia exploringE. coliO157 colonization and shedding in extensive beef cow systems.Upon my return to Colorado State University I continued researchingE. coliO157 in dairy cows.Our team analyzed data related to shedding in intensive dairy systems and examined the dynamics of farm ecology on the prevalence ofE. coliO157, as well as the underlying bovine microbiome influencing colonization and shedding.
My Ph.D. research focused on the epidemiology underlying increasing rates of adult dairy cow death on U.S. farms.We introduced novel concepts for on-farm record keeping including a dairy cow death certificate.Work in this area continues with a focus on the lifetime impacts and opportunity costs associated with disease and death on dairies.
