Geospatial data gives a fresh view.
ICONZ has twenty-one partners across the world
who have joined together to combat a group of
diseases that move between animals and humans.
These diseases are debilitating, ultimately deadly
but often overlooked. Each partner will contribute
a part of the solution that will save lives and secure
livelihoods, by controlling zoonotic disease across
the human and animal populations.
Dear Readers,
Welcome to the sixth edition of the
ICONZ Magazine.
As an EC project, we are currently reflecting
upon our progress in the last eighteen months
and compiling our third periodic report. As we
plan for our fourth and final period, we do so
with great anticipation at seeing the outcomes
of our hard work.
In this issue, we first turn our attention towards
our Advisory Council, and welcome our newest
member Prof Richard Kock, a veterinarian
specialising in One Health and the ecology
of wildlife disease in Africa.
Next we speak to Prof Ignacio Moriyón (Work
Package Leader 5) and his team about their
work on neglected bacterial zoonoses.
Prof Jim Scudamore (Work Package Leader 2)
then tells us about his neglected zoonoses
research projects database.
Finally, Ward Bryssinckx of Avia-GIS
demonstrates how mapping can help us
visualise and draw conclusions from our data.
Experts working together with affected
communities is what makes ICONZ unique.
Thank you for being part of the team; and
together we’ll be part of the solution.
Kind regards,
Sue Welburn

The neglected of the neglected
Ignacio Moriyón, leader of Work Package 5, has recently conducted a first stakeholder meeting with
a view to taking action on brucellosis in Morocco. It was a highly successful, small-scale intervention
that included local officials, students, vets and also farmers’ representatives.
The war on brucellosis formally
began in 1887 when Scottish
pathologist Dr David Bruce
established the causal relationship
between the organism and the
disease, then known as Malta
fever. Shortly afterwards, the
Mediterranean Fever Commission
traced the origin of the disease
to infected ruminants. Since then
many battles have been won and
numerous countries in the world
are able to declare themselves
brucellosis free, thanks to animal
vaccination, test and slaughter
programmes and pasteurization
techniques.
However we are nowhere near winning the war
and, for many countries in Africa, brucellosis is
still taking a heavy toll. Despite being a chronic
disease with the risk of disabling consequences,
brucellosis is rarely fatal in affected humans
(about 2%). With no specific clinical picture,
aside from recurrent fever, it is often
It’s hard but we
have to get the
message across
to people that no
matter what they
think, raw milk
is full of bacteria.”
misdiagnosed as drug-resistant malaria. It is
likely that tens of thousands of people across
Africa are affected by this debilitating disease
despite the existence of animal vaccines and
other means of control. It has become the most
neglected of the neglected.
“The meeting in Sidi Kacem was very well
organised. I travelled to Africa with a colleague
from Spain, Dr Jose Maria Blasco, who is a world
expert in brucellosis vaccination. We gave two
talks. I spoke about the basis of brucellosis
vaccination and Dr Blasco talked about how to
get the most from the vaccines that we currently
have,” explained Ignacio.
“Then on the second day we went into the field
to see a farm with cattle and sheep. We used
a placebo to demonstrate the conjunctival
vaccination technique to students and vets from
the Moroccan Food Safety Agency (ONSSA).”
The conjunctival technique involves putting a few
drops of the vaccine into the eye of the animal.
(A video showing injectable and conjunctival
techniques can be found on the ICONZ
website: www.iconzafrica.org/category/videos)
“It went very well. On the third day we went for
a meeting with the local authorities and it was
clear that they were listening carefully.”
The first task Ignacio has to address is to
convince people that their sheep and cattle
actually have brucellosis, such is the strong
bond between farmers and their animals in
the communities involved.
“It’s hard but we have to get the message across
to people that no matter what they think, raw
milk is full of bacteria. Sometimes you tell people
and they say: ‘Our sheep and cattle are not like
that!’ But these are smart people. I think we
should show them the milk under the microscope.”
Having convinced all those concerned of the
existence of the disease, it then falls to the
ICONZ team to put the case for conjunctival
rather than subcutaneous vaccination of
livestock – a more effective method.
“Most vets here in Spain were reluctant to move
from subcutaneous to conjunctival but when
they did, they said: ‘Wow, forget needles,
forget syringes’. Students in Morocco, who had
never vaccinated conjunctivally before, were
able to do it first time,” Ignacio reports.
However, despite his enthusiasm, the WP5
interventions are not without difficulties.
“At this time the conjunctival formulation is not
commercially available. The subcutaneous form
can be adapted but it would be great to get it
in a ready-made dropper. Then we also have the
problem that, because of the political and security
situation, we can no longer work in Mali and there
are problems working in central Nigeria. So
our next steps will be in Morocco and also we
are organising a course in Tanzania in May.”
The course in Tanzania will focus on the impact
of community-based interventions, for example
educating and promoting best practice for
health to farmers, pastoralists, women and
families. Moroccan colleagues are also
planning an education campaign.
The outlook, of course, needs to be long term
with goals beyond the ICONZ timeframe.
But people are talking more about brucellosis,
and awareness has been raised. The most
neglected of the neglected is getting a little
attention at last.
Taming brucellosis in Tanzania
– Lawrencia Wankyo Mbahi
is making sure brucellosis
is a little less neglected than
it once was.
As an ICONZ-funded MSc student at
Sokoine University of Agriculture in Tanzania,
Wankyo has taken on the task of working on
the socio-economics of brucellosis in humans.
She conducted a two year study in the
Morogoro region involving 1807 out-patients
complaining of fever, as well as local officials,
doctors, lab technicians and village leaders
amongst others.
“I had different groups of people from all age
categories and with different occupations
such as pastoralists, farmers, employed
people and students. After screening, we
found a substantial number of those tested
had brucellosis. Many of them were surprised
by the diagnosis and were not aware they
might have brucellosis; even the laboratory
technicians testing the samples were
surprised.
Brucellosis is not routinely diagnosed
in Morogoro; only two private health
centres offer the test. So obviously there’s
misdiagnosis as malaria, typhoid and
venereal diseases such as syphilis. Some
people have brucellosis for a long time
leading to a range of health problems
causing permanent disabilities in any
organ of their bodies.
In socio-economic terms, misdiagnosis is
expensive and time-consuming. People incur
great expense treating the wrong disease
and also fail to conduct their daily activities
because they are weak most of the time.
Some relate the disease to supernatural
causes.
It’s important to control the disease in livestock
but raising public awareness about how the
disease is transmitted is key, because it is
a genuine threat to public health.”

Back to
databasics
Veteran vet Jim Scudamore tells ICONZ Magazine
why statistics are so vital.
For many people, beginning
retirement is likely to involve some
slippers, a newspaper and perhaps
a spot of golf. For Jim Scudamore,
retiring in 2004 meant taking
on (amongst other things) an
appointment as Professor of
Livestock Veterinary and Public
Health at the University of Liverpool
and the leadership of ICONZ
Work Package 2 “Mapping Global
Research on Neglected Zoonoses.”
As a former Chief Veterinary Officer for the UK
with a background in research, fieldwork and
policymaking he was the ideal candidate for
this vitally important work package.
“What we are trying to do is create a database
to give us a clear picture of what’s going on
in terms of research into the eight diseases.
We then want to analyse results for each
disease to see where the gaps are in the
understanding of the diseases and the
availability of tools for their control. This
information can then be used to identify the
research that is needed to ensure that tools,
such as diagnostic tests, vaccines and cost/
benefit analyses, are developed to help control
the neglected zoonoses. That’s going to be
very useful to many organisations.”
Jim and colleagues began by asking researchers
to fill out questionnaires, letting them know what
work was currently being undertaken, but the
response was poor. Thankfully another EU
Project called EMIDA, set up to look at emerging
infectious diseases, was able to assist and
provide a great deal of information on the eight
zoonoses, helping support the first database.
The next step was to analyse the published
work relating to the ICONZ diseases and build
a second, publications database.
“We looked at PubMed because it’s an open
source of data. We downloaded all the papers
produced since 1950. The numbers of
publications certainly reflected the neglected
nature of the diseases. We did a comparison with
E. coli and a few other diseases and contrast
was clear. The exception was anthrax because
of its potential for bio-terrorism,” he explains.
A considerable amount of information was
generated, but the analysis had to go beyond
simple numbers of papers. They developed a
semi-automated system that could look at all
the papers and place them in a category like
basic science, costs and burdens, control and
management, diagnostics and vaccines and
lastly epidemiology and risk. This methodology
is still being evaluated for its accuracy.
The third database that Jim and his team have
recently been working on is a funder’s database.
The team have searched the websites and
databases of the main funders, to pull out
currently funded projects and categorize them
for the database.
The last step will be to produce a report,
compiling the three data sets and defining the
research gaps for each disease.
“One thing that’s come out of the work we have
done is how few papers have been published
on costs and burdens. But unless you can
demonstrate that it costs a lot, policy makers
will take no notice,” he warns. “Neglected
zoonoses are neglected because there’s
not enough evidence to show that they’re a
problem. The whole point of this is to attract
policy makers’ attention and persuade them
of what needs to be done.”

Work Package 3, Knowledge and Information on Neglected Zoonoses,
has been using everything from Google Earth to GPS receivers
to assemble a raft of geospatial data and find a new way of looking
at neglected zoonoses.
Says Ward Bryssinckx of Belgian
partner Avia-GIS: “Within ICONZ,
geographical information systems
(GIS) have been used to process
data from a variety of sources.
The maps below show how
bovine tuberculosis (bTB) is
clustered in the Morogoro study
area in Tanzania. It enables us
to see at a glance the area with
a high rate of bTB in the context
of major rivers and roads and the
boundaries of nature reserves.

conclusions about the effect
the livestock-wildlife interface
is having on bTB. We can also
include information that changes
continuously like land surface
temperature or vegetation.”
Descriptive maps like these have been
produced for all the ICONZ case study areas
showing the baseline data that has been
collected. A Livestock Mapping Tool has been
developed to assist researchers in selecting
appropriate sample sites for livestock studies.
Finally, custom maps will be created in order
to visualize the outcomes of the ICONZ case
study interventions.
