About us The Pirbright Institute is a world leading centre of excellence in research and surveillance of virus diseases of farm animals and viruses that spread from animals to humans.
• Working to contain, control and eliminate economically and medically important diseases • Contributing to global food security and health, improving quality of life for animals and people • Combining highly innovative fundamental and applied bioscience • Approximately 250 staff • Annual income ~£29M • £76.9M strategic investment from the UK Biotechnology and Biological Sciences Research Council during 2011-12
Impact: UK economy
Annual contribution of livestock • Foot-and-mouth outbreak to the UK economy 2001 cost UK economy >£2-8bn Game Cattle £1,600M £4,487M • Calf pneumonia costs UK economy £54m p.a. Sheep £628M Poultry • IBV costs UK economy £7,500M £22m p.a. Horses £4,000M • Prediction and rapid Pigs £735M response to bluetongue in 2007 saved economy £0.5bn p.a.

Research at the Institute is a synergistic combination of fundamental and applied science, based upon a wide range of expertise, and unique biological and physical resources. The science strategy is delivered through three strategic programmes:
• Avian Viral Diseases • Livestock Viral Diseases • Vector-borne Viral Diseases
Each programme comprises a platform of fundamental science projects that provide the new knowledge that is then translated, within the programmes, into applied science. Institute Strategic Programmes

farm-to-farm Data can be used to: spread
animal-animal • Monitor the global circulation transmission and transboundary movements within host of FMDV pathways
cell-to-cell • reconstruct transmission trees infection
within outbreaks X X X X X X X Population X X X X X X X diversity X X X X X X • reveal processes that drive intra-cellular dynamics evolution 5’ AAAA Orton et al., Phil Trans B (2013) Tools for FMD Control
Success of reactive strategies, such as quarantines and culling, depend upon how long animals infectious before confirm disease, usually based on clinical signs
Proxy measures used based on viraemia/virus excretion
Black – transmission attempt outcome Green – virus isolation from nasopharynx Red – virus isolation from blood Blue – virus isolation from probang
Charleston et al., Science (2011) External partnerships
• Diamond Light Source synchrotron • Located in South Oxfordshire on the Harwell Science and Innovation Campus. • Covers the area of 5 football pitches
• Recent approval to use beamlines for FMDV
• Provides capability to define viral capsid structures at high resolution FMD Capsid vaccines – safe and stable
Stabilised capsids treated 2h at 56ºC (or for 30min at pH5) are intact after sucrose density gradient analysis

Current diseases of interest are:
• Nairobi sheep disease • African Horse sickness • Peste des petits ruminants • African swine fever • Pestiviruses • Avian influenza • Bovine and human respiratory syncytial • Bluetongue viruses • Foot-and-mouth diseases • Rotaviruses • Infectious bronchitis • Schmallenberg • Infectious bursal disease • Swine influenza • Marek’s disease • Zoonotic arboviruses Social and economic impact
The Pirbright Institute provides knowledge, tools, technologies and advice to a variety of end users in science, agriculture, veterinary medicine, pharmaceutical industries and policy. Activities include:
• Diagnostic Services and Surveillance • Knowledge Exchange and Commercialisation • International Training • Health and Safety, Environmental Protection, Biosecurity, and Risk Management • Public Engagement Social and economic impact
Fundamental science underpins practical solutions to many of the challenges faced by farmers, vets and policy makers. The benefits can be world-changing:
• The Institute has played a role in eradicating rinderpest, which is estimated to save the economies of Africa around US$1 billion per year.
• Advice from the Institute led to a successful voluntary vaccination programme against an incursion of bluetongue virus in 2007-8, saving the UK around £485 million and protecting 10,000 jobs.
