Dr Deborah Hoyle

Research Fellow


I graduated from the University of Cambridge with BA (Hons) Pathology in 1991 and Vet MB, MRCVS in 1994. I spent a year at the University of Oxford studying the epidemiology of human infectious disease, before working for a short period in mixed clinical practice. In 1996, I moved to the Royal (Dick) School of Veterinary Medicine, Edinburgh, to study for a doctorate, investigating the early immune response to Fasciola hepatica infection in cattle (2000). Following this, I joined Professor Mark Woolhouse’s group, initially on a quarantine surveillance project, examining the risk of zoonotic disease importation by pets into the UK and then as a post-doctoral researcher studying the molecular epidemiology of antimicrobial resistant commensal and pathogenic Escherichia coli in beef cattle. From 2005-2015, I took a ten year career break to raise a family. I returned to research in 2015 with a Wellcome Trust Career Re-entry Fellowship investigating the epidemiology of Shiga toxin positive non-O157 E.coli on farms throughout the UK. I am interested in infectious disease epidemiology, antimicrobial resistance, surveillance and disease control.

Research summary

Molecular epidemiology of zoonotic and emerging pathogens, antimicrobial resistance, disease surveillance and control.

Current research interests

I am a qualified veterinarian and researcher, with research interests in the One Health field, focussing on the epidemiology of veterinary pathogens and zoonoses, antimicrobial resistance (AMR) and emerging disease. My current projects focus on the molecular epidemiology of foodborne zoonotic pathogens Shiga-toxin non-O157 Escherichia coli in cattle, the role of mobile genetic elements in the dissemination and retention of AMR genes in livestock, and the impact of withdrawing therapeutic levels of zinc oxide supplementation during piglet weaning on stakeholder antibiotic use and on-farm AMR gene carriage. As a veterinarian, I have further interests in the epidemiology and control of endemic disease in livestock and the impact of disease on animal welfare.

Current project grants

Past project grants
