which may in turn drive innovation and cost
savings. However, this requires management
agency capacity for contract specification,
tendering and audit to ensure contractors meet
performance requirements. Direct operational
service delivery by the management agency
itself may offer greater management control,
but may lead to unwanted agency expansion. In
practice, a mix of contracted and direct service
delivery may be appropriate.


15.2.13 Research

While there is an existing large body and litera-
ture of research on TB in cattle (some of which
has been summarized in earlier chapters) fur-
ther research may be required to address local
technical or biological problems, to improve
programme cost-efficacy, or to mitigate adverse
operational or social impacts. Research require-
ments will vary from programme to programme



  • often reflecting programme maturity – but will
    likely be directed towards cost-effective applica-
    tions of new diagnostic methods, animal record-
    ing, or control policies within existing TB
    programmes.
    Research planning and delivery processes
    will need to reflect available institutional
    arrangements and structures. A management
    agency may have direct access to research
    capacity, or may need to utilize external capacity
    in institutes or universities. In either case the
    management agency should possess or be able to
    co-opt the expertise needed to identify research
    needs, develop and manage a research portfolio
    to meet these needs, and to oversee the planning
    and delivery of specific research projects. It may
    also need processes to deal with possible conflicts
    of interest between funders and research provid-
    ers, and to ensure intellectual property rights
    and commercial interests are appropriately
    managed. Research projects must be designed to
    ensure delivery of clearly specified outcomes
    under fixed budgets.
    Information derived from analysis of data,
    outcomes of relevant research, feedback from
    farmers and audit findings should be used to
    modify plans, policies and the implementation
    process to ensure these remain best-aligned to
    current programme objectives and are cost


effective (Tweddle and Livingstone, 1994;
Sheridan, 2011; Livingstone et al., 2015b).

15.3 Impact of Wildlife Reservoirs on
Tuberculosis Strategies

The finding of TB in a reservoir or maintenance
wild animal host (Morris and Pfeiffer, 1995;
Palmer, 2013) in high GNI economy countries
may initially be seen as scientifically interesting
or a novel nuisance. Once both the full geo-
graphic distribution of the TB maintenance host
and its impact as a source of infection for cattle
have been determined, then the finding can
range from minor inconvenience to a major set-
back. Where the maintenance host is of limited
distribution, it may have a relatively minor
impact on a TB programme, such as with infec-
tion of white-tailed deer in Michigan in the USA
(Palmer, 2013) and in elk and white-tailed deer
in Canada (O’Brien et al., 2011). However, where
a maintenance host has a wide distribution and
is an effective vector of infection for cattle, such
as with badgers in the UK and Republic of Ire-
land (Abernethy et al., 2006; More and Good,
2006; Wilson et al., 2011), wild boar in Spain
(Naranjo et al., 2008) and possums in New Zea-
land (Nugent et al., 2015a) this greatly increases
both cost and time frames required to achieve TB
freedom or eradication goals.
The presence of a significant wildlife main-
tenance host introduces ecological, environ-
mental and possibly societal factors that extend
beyond the immediate farming environment.
These factors may vary greatly from situation to
situation, and will require locally designed
responses. Altogether, these will be more chal-
lenging and complex than the largely standard
test, slaughter and quarantine processes that
are sufficient for effective control where the dis-
ease is limited to farmed cattle. Controlling TB in
wildlife requires different sets of knowledge and
analysis of much more complex situations. A
programme that requires disease management
in wildlife as well as cattle is likely to impact on
people who may have little interest in cattle TB
control, whereas cattle farmers and TB control
stakeholders may have little interest in wildlife
management. This can lead to conflict based on
differing attitudes towards controlling livestock
