A Novel Way to Detect Infection Status of Wildlife likely to have Bovine Tuberculosis (‘Badger Infection Forensics’)

Summary of the impact

A novel, reliable, non-invasive and rapid method has been developed to detect excretion of Mycobacterium bovis, the causal agent of bovine tuberculosis (bTB), into the environment ("shedding") by wildlife hosts. This test has been used to establish the efficacy of the bTB vaccine on reducing environmental contamination by shedding of M. bovis in the faeces (from January 2010). It has also become an important monitoring tool used by VisaVet (European Veterinary Health Surveillance), targeting bTB in wild boar and red deer (from July 2010) to establish bTB reservoirs and take action to protect the cattle stocks. Farmers will benefit and now be able to monitor environmental contamination by M. bovis, which allows them to establish biosecurity best practice.

The method includes both a presence/absence score and a quantitative assay of infectious disease load in faecal matter in the environment. This is the first standard assay to determine environmental contamination, the main route for disease spread to cattle, and allows evaluation of the impacts of vaccination, culling and increased movement of badgers during disease- management strategies. This test also enables precise monitoring of cattle herds infected with bovine tuberculosis (bTB) as it advances from the South West to the North East of England.

Diagnosis and Control of Neosporosis in Cattle

Summary of the impact

The parasite Neospora caninum is the leading cause of abortion in cattle in the UK, resulting in around 6,000 abortions per year; and a $1.3b pa international problem. There are no effective drugs or vaccines to control neosporosis. University of Liverpool (UoL) research on the development of diagnostic tests, understanding the pathogenesis, epidemiology and transmission of N. caninum has made an important contribution to developing best practise herd health schemes, now offered by the Animal Health and Veterinary Laboratories Agency (AHVLA) and by a commercial company `myhealthyherd', to eradicate N. caninum infection from a herd. This has enabled cattle farmers to improve their businesses by reducing abortion rates and other costs associated with neosporosis.

Risk-based surveillance and testing defines government policy on bovine tuberculosis

Summary of the impact

A University of Glasgow bovine tuberculosis (bTB) surveillance model was fundamental to new Scottish Government policy on bTB testing. Implemented on 1st January 2012, the policy change used the Glasgow model to indicate which cattle herds can be exempt from routine testing while still maintaining Scotland's Officially bTB Free status. In 2012 this translated to exemption of more than 30% of Scottish herds from routine testing, with an associated government saving of £150,000. The revised policy also provided savings to the Scottish farming industry in the region of £100,000 (2012) and limited the risks of bTB testing to farmers, veterinarians and cattle. The rapid success of the ground-breaking Scottish research-led bTB policy development has been highlighted by the Civil Service as best practice and has been presented to numerous policy audiences including the European Commission, providing the opportunity to transform industry practices and livestock surveillance policy across the UK and beyond.

TB in Cattle and Badgers: Improving Control of a Multi-species Disease

Summary of the impact

The bovine tuberculosis (TB) research programme led by Professor Donnelly at Imperial College has been informing policymakers for over a decade. Professor Donnelly played a leading role in the design, oversight, analysis and interpretation of the £50 million Randomised Badger Culling Trial (RBCT, 1998-2006), overseeing a bovine-TB research team at Imperial since 2001. The RBCT compared two candidate culling policies (large-scale culling repeated annually and one-off small-scale culls near farms affected by bovine TB) with areas in which no badger culling took place. Informed by RBCT results (in which widespread culling decreased cattle incidence inside the culling area but increased it on neighbouring farms), the Secretary of State Hilary Benn ruled out badger culling as a control measure in July 2008. However, the coalition government took a different view and in December 2011 announced that farmers could apply for licences to undertake farmer-led (and farmer-funded) badger culling to control TB in cattle. Several of the government's licensing requirements for badger culls in England were based on many of the team's results. In contrast, having proposed in 2010 a large government-led cull, the Welsh government chose in March 2012 to vaccinate, rather than cull, badgers informed by the same set of results.

1i. Eliminating trypanosome carriage in Ugandan cattle prevents sleeping sickness in humans, stimulating the formation of “Stamp Out Sleeping Sickness (SoS)” a Public Private Partnership that is eliminating the disease from Uganda

Summary of the impact

Impact: Economics, policy, animal and human health: In 2006, SoS (a Public Private Partnership-PPP) was established involving: University of Edinburgh, a pharmaceutical company, a charity, and the Govt. of Uganda to control sleeping sickness by eliminating Trypanasome carriage in cattle. The prevalence of trypanosomiasis has been reduced by 75% and sleeping sickness cases have fallen year on year since the PPP was established and Uganda has received a cost benefit between US$125 and $400M

Beneficiaries: The Ugandan population, Ugandan Cattle population.

Significance: Sleeping sickness, which is difficult to diagnose and treat in humans, is often fatal. Ten million Ugandans are at risk from sleeping sickness. SoS established a veterinary network in Uganda producing

Attribution: Professor Welburn (University of Edinburgh, UoE) founded SoS and developed essential diagnostic techniques.

Reach: SoS provides a model for the elimination of the disease across sub Saharan Africa in an economically sustainable fashion - with over 22 million people at risk.

Advancing analgesic use in cattle

Summary of the impact

The use of non-steroidal anti-inflammatory drugs (NSAIDs) for their pain-relieving properties in cattle medicine has lagged behind that of other species (e.g. companion animals) where analgesic use is now routine. University of Nottingham (UoN) research exploring the attitudes of vets and farmers to the use of NSAIDs in cattle, and subsequent marketing by Boehringer Ingelheim, a multinational pharmaceutical company, has led to a substantial increase in analgesic use. UoN research increased sales for Boehringer Ingelheim and almost doubled the UK market value of NSAIDs for use in cattle. With administration of up to 2 million additional doses per year, the research had clear benefits for animal welfare.

Global Reduction in Equine Colic through a Novel Tapeworm Intection Test

Summary of the impact

Research at the University of Liverpool (UoL) has demonstrated the importance of intestinal tapeworm infection as an important and hitherto unrecognised risk factor for a major life-threatening acute intestinal disease (colic) in the horse. A novel serological test for exposure to the tapeworm infection was developed at UoL to provide a diagnostic tool for research and clinical applications. As a result, "best practice" equine preventive healthcare programmes now include anti-helminth and tapeworm control protocols and anti-tapeworm anthelmintics are licensed for use in the horse and marketed throughout the world. This research has had a major impact on equine health resulting in welfare and economic benefits for horses, their owners, veterinary practices and industry.

Mathematical modelling of livestock infection to inform policy for future epidemics and control of disease outbreaks

Summary of the impact

Mathematical modelling of livestock infections and disease control policies is an important part of planning for future epidemics and informing policy during an outbreak of infectious disease. Researchers in the Mathematics Institute, University of Warwick, are considered to be at the cutting-edge of developing policy-orientated mathematical modelling for a number of livestock infections. Such models have been used to inform government policy for foot-and-mouth disease (FMD) and a range of other infections including bovine tuberculosis (bTB) and bee infections. From 2008, their work with responsible national and international agencies has focused on statistical inference from early outbreak data, formulating models and inferring parameter values for bTB infection spread within and between farms, developing predictive models of FMD outbreaks in the USA, and extending such models to areas where FMD is endemic. This research has helped to shape policy and determined how policy-makers perceive and use predictive models in real-time.

1n. Control of bovine viral diarrhoea virus in livestock through evidence-driven behaviour changes on farms and through veterinarians

Summary of the impact

Impact: Economic / animal health and welfare: Established health schemes to control Bovine Viral Diarrhoea (BVD) on Scottish farms and subsequently underpinned the rationale for cost-effective control strategies that have been adopted in health schemes around the UK. The farm-level savings to the industry from future eradication are estimated by Scottish Government to be £50- £80m.

Significance: BVD is a major endemic disease of cattle in Scotland costing the dairy industry about £38M per year and an additional £11M to consumers.

Beneficiaries: Farmers, cattle, animal health authorities.

Attribution: Professors Gunn and Stott (SRUC).

Reach: The associated health schemes began in Scotland (HI Health) and now operate throughout Britain (UK CHeCS (Cattle Health Certification Standards) Health Scheme). The research underpins BVD control schemes in Ireland and other EU Member States resulting in an avoided output loss of between €500 to €4,000 per dairy farm per year.
