Tactics For Identifying And Eliminating Tritrichomonas Foetus From Infected Beef Herds, Jeff D. Ondrak

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

The protozoan, Tritrichomonas foetus (TF), has been recognized as a cause of bovine infertility for more than 100 years (Skirrow and BonDurant, 1988). As an obligate parasite of the bovine reproductive tract its control and eradication seems achievable (Harding, 1950). However, this disease continues to trouble United States cattle producers and a recent epidemic in the Western US has lead to increased interest in research and regulatory efforts (Cima, 2009). Outbreak investigations were carried out on three Nebraska ranches to assess the efficiency of currently available diagnostic tests, culture, gel polymerase chain reaction (PCR), and real time PCR (rtPCR), in …

Dairy Animal Care: Quality Assurance

Nebraska Beef Quality Assurance Program

Dairy producers are encouraged to participate in the voluntary Dairy Animal Care and Quality Assurance (DACQA) Certification program. The purpose of this program is to enhance and demonstrate quality animal care practices, which assure food safety, quality and value as well as enhance consumer confidence in the milk and beef products that are harvested from cattle on America’s dairy farms.

School Of Veterinary Medicine & Biomedical Sciences: 2010 Annual Report

School of Veterinary and Biomedical Sciences: Information and History

On September 4, 2009, The Department of Veterinary Medicine and Biomedical Sciences was renamed the School of Veterinary Medicine and Biomedical Sciences. The School is informally organized into six functional areas: • Undergraduate Teaching • Research and Graduate Studies • Extension • Veterinary Diagnostic Center (VDC) • Great Plains Veterinary Educational Center (GPVEC) • Professional Program in Veterinary Medicine (PPVM) While teaching and research activities bridge the entire faculty, subsets of the faculty are primarily involved with one area, i.e., the undergraduate program, the research and graduate program, the veterinary medical students clinical teaching at the GPVEC, the pre-clinical teaching …

Isolation And Cultivation Of Equine Corneal Keratocytes, Fibroblasts And Myofibroblasts, Dylan G. Buss, Elizabeth A. Giuliano, Ajay Sharma, Rajiv R. Mohan

Pharmacy Faculty Articles and Research

Objective—To establish an in vitro model for the investigation of equine corneal wound healing. To accomplish this goal, a protocol to isolate and culture equine corneal keratocytes, fibroblasts and myofibroblasts was developed.

Animal material—Equine corneal buttons were aseptically harvested from healthy research horses undergoing humane euthanasia for reasons unrelated to this study. Slit-lamp biomicroscopy was performed prior to euthanasia by a board-certified veterinary ophthalmologist to ensure that all samples were harvested from horses free of anterior segment disease.

Procedure—Equine corneal stroma was isolated using mechanical techniques and stromal subsections were then cultured. Customized media at different culture conditions was used …

Gene Delivery In The Equine Cornea: A Novel Therapeutic Strategy, Dylan G. Buss, Ajay Sharma, Elizabeth A. Giuliano, Rajiv R. Mohan

Pharmacy Faculty Articles and Research

Objective—To determine if hybrid adeno-associated virus serotype 2/5 (AAV5) vector can effectively deliver foreign genes into the equine cornea without causing adverse side effects. The aims of this study were to: (i) evaluate efficacy of AAV5 to deliver therapeutic genes into equine corneal fibroblasts (ECFs) using enhanced green fluorescent protein (EGFP) marker gene and (ii) establish the safety of AAV5 vector for equine corneal gene therapy.

Animal Material—Primary ECF cultures were harvested from healthy donor equine corneas. Cultures were maintained at 370C in humidified atmosphere with 5% CO2.

Procedure—AAV5 vector expressing EGFP under control of hybrid cytomegalovirus (CMV) + chicken …
