MANAGING LIVESTOCK ANTIBIOTIC RESISTANCE

"THE IMPACT OF ANTIBIOTIC
resistance for the producer is that
it limits the profitability of his or
her business."

- Martin Guillet, Thermo Fisher Scientific

managing antibiotic resistance simply by identifying a specific target.   
"Until recently, common practice
was to use a broad-spectrum antibiotic to treat a sick animal or group
of animals," he explained. "A diagnostic test identifies the specific bacterial pathogen causing the clinical
signs, and that information allows
veterinarians to know the specific
antibiotic to prescribe to control or
eradicate the pathogen. This enables
a more targeted, prudent use of antibiotics, which can help the entire industry manage the issue of antibiotic
resistance."
Diagnostics technology is advancing extremely rapidly, providing
new approaches to testing that are
more precise and offer rapid results.
"Not so long ago, diagnostics
were conducted by growing cultures
in a Petri dish, and that took many
days or weeks to get results," he
said. Today, ELISA technology and
molecular tests on different sample
types - using a swab, tissue, saliva
or blood samples - can provide
results the same day. Technology,

science, awareness and education
are also creating a mindset, from the
producer all the way to the consumer, who desires more information.
"Until recently, diagnostics was
seen as an expense - something
that you could do without," he noted.
"Now, we are seeing a change in
the mindset of the value chain that
diagnostics is an investment and can
have a positive impact on the entire
value chain, be it as a disease prevention tool that can reduce the use
of antibiotics or by allowing prudent
use of antibiotics."

Diagnostic use in
the industry
In some countries, regulations
require diagnostics to be performed
before an antibiotic is prescribed
to confirm the proper treatment is
administered.
"Mastitis in the dairy industry
is an example - there are several
countries in Europe that require a
diagnostic test to be performed to
identify exactly which pathogen
is causing the disease," he said. 
"Antibiotic use is not allowed unless
a diagnostic test has been completed." Guillet anticipates this type of
regulation could become the norm
over time, driven by public health

agencies and global consumers.
"Consumers will continue to
scrutinize how their food is being
raised," he said. "We're already
seeing it in certain countries where
consumers are changing their eating
habits because of the fear of a presence of pathogens or antibiotic residue. Consumer pressure already has
an effect on industry practices."

Conclusion
The challenge and opportunity
for the entire value chain, from
farm gate to plate, is to produce a
sufficient amount of food for the
world's growing population while
minimizing the potential threat of
antibiotic resistance and the spread
of zoonosis.
Targeted medicine practices, using the right antibiotic that's linked
to the specific pathogen causing the
illness, allow diagnostics to help
play a crucial role in managing antibiotic resistance and, at the same
time, help farmers produce quality food while minimizing risk for
foodborne diseases. ■
