Equine Medicine and Surgery Research

Meet the researchers and lecturers

Dr Yolandi Smit

BSc, BVSc, MSc, MMedVet
Section Head
Senior Lecturer: Equine Surgery

Tel: +27(0) 12 529 8141

ORCID ID: 0000-0002-4298-4496

Dr Smit’s research focused on orthopaedics in the equine athlete. Studies included musculoskeletal radiographic changes in 500 yearling Thoroughbreds horses at sales. Her research expanded to evaluate musculoskeletal radiographic changes of Endurance horses in South Africa. Further exploration to was done in the field of osteoarthritis when the  intra-articular platelet-rich-plasma administration was researched. Currently her research focus now includes pre-operative and post-operative exploratory laparotomy complications (such as surgical site infections) and the management impact of treatment options there on and certain prognosticator markers (i.e., Lactate).  


Dr Adrienne Viljoen

Dr Adrienne Viljoen

Dr Viljoen’s main research focus in the past involved the effects of synthetic colloids, a 4% modified flip gelatine and a 6% hydroxyethyl starch on haemodilaution, colloid osmotic pressure and haemostats in horses. Dr Viljoen is currently involved in several equine medicine projects and includes studies such as the clinical and clinicopathological findings in horses with equine encephalitis virus, the prevalence of Gastrodiscus in equids as well as a multicenter study investigating antimicrobial use and resistance in veterinary hospitals.


 

Dr Christina Eberhardt

DVM, Dr. med. vet, DipACVIM
Senior Lecturer: Equine Internal Medicine

Email: [email protected]

Dr Eberhardt is an active researcher in the field of equine cardiology. Her main research focus is echocardiography including advanced modalities such as speckle tracking echocardiography. Dr Eberhardt has developed a point of care echocardiography protocol for the evaluation of horses in the emergency and critical care situation. Her research also includes studying advanced teaching methods for echocardiography training. In addition, she collaborates with the Department of Wildlife Medicine to study the heart rhythm of white rhinoceros and other wildlife species using a telemetric mobile ECG device.


 

Dr Ingrid Cilliers

BVSc, BVSc(Hons), MMedVet
Senior Lecturer: Equine Surgery

Email: ingrid.cilliers@up.ac.za

Dr Cilliers’s research for her MMedVet degree was based on the incidence of catastrophic breakdowns of racehorses on the Gauteng racetracks.

Dr Maitland-Stuart is the equine ambulatory clinician for the Equine Clinic of the Onderstepoort Veterinary Academic Hospital. Her main focus is on exposing students to day-one requirements of an equine veterinarian and allowing them to gain confidence with these skills. Dr Maitland-Stuart has done research into Gastrodiscus aegyptiacus infections in equids, including prevalence of infection in different groups as well as risk factors associated with infection. She is currently involved in a trial investigating a product to be used to provide symptomatic relief to equids suffering from insect bite hypersensitivity (IBH). 


 

 
Dr Graeme Gordon Wallace

BVMS, MRCVS
Clinical Assistant: Equine Internal Medicine

Email: [email protected]

Dr Wallace is a resident in Equine Internal Medicine. His clinical and research interests include all aspects of internal medicine, but with particular emphasis on the emerging field of the gastrointestinal microbiome and its potential links to a number of disorders in the equine population. 


 

 

Dr Graeme Brandon Piketh

BVSc, MSc
Clinical Assistant: Equine Internal Medicine

Tel: +27(0) 12 529 8071
Email: [email protected]
ORCID ID: 0000-0002-1556-3418

Dr Piketh is an up and coming young researcher with goals aiming at research relating to the cardiovascular responses to systemic and infectious diseases in horses. His research interests also extend to immune mediated disease in horses with a focus on inflammatory bowel disease. His current research project aims at describing clinical and clinicopathological changes seen in horses, naturally infected with equine encephalosis virus.
