Latest Data Confirm Imidacloprid Remains Highly Efficacious After More Than a Decade of use

December 13, 2010

MONHEIM, Germany, December 13, 2010 /PRNewswire/ –

– New Publication From International Experts Demonstrates Fleas Worldwide
Continue to be Highly Susceptible to Imidacloprid

In a study published online last week in Medical and Veterinary
Entomology, international experts reported the latest data on flea
susceptibility to imidacloprid, revealing that after more than a decade of
widespread use around the world, there is no evidence of resistance to this
invaluable treatment.

The study looked at data compiled between 2002 and 2009 by the
International Flea Susceptibility Monitoring (FSM) programme from monitoring
centres in Australia, Germany, France, UK and USA. The data showed that, of
the more than one thousand samples tested over the past eight years, all were
confirmed to be susceptible to imidacloprid.

“These results are great news for veterinarians and pet owners alike,”
said Dr Byron Blagburn, Distinguished University Professor, College of
Veterinary Medicine, Auburn University
, USA. “They show that imidacloprid,
one of the most widely used active ingredients for flea control in pets,
remains as effective against fleas now as it was when it was first launched.”

Imidacloprid is the key active ingredient in Advantage(R) and related
products developed for the effective control of fleas and other parasites in
companion animals.

The International FSM programme is the first and only monitoring
initiative in the field of companion animal parasites. The FSM initiative
includes a group of internationally renowned, independent researchers who
work together with Bayer Animal Health to monitor the susceptibility of fleas
to imidacloprid.

“In order to prevent resistance to treatments such as imidacloprid,
careful and coordinated monitoring is essential in order to detect as early
as possible any potential shifts in susceptibility. The FSM programme is
unique in terms of geographical scale and duration. It is an excellent
example of a pharmaceutical company collaborating with academic organisations
to ensure the efficacy and safety of its products,” said Ian Denholm,
Principal Scientist, Rothamsted Research, Harpenden, UK.

Bayer Animal Health supported the initiation of the FSM, in partnership
with an international panel of experts, in order to monitor the
susceptibility of flea populations to imidacloprid, the active ingredient of
Advantage(R). “We are delighted to see that, once again, the data from the
FSM programme show that veterinary professionals and pet owners can continue
to trust Advantage(R) to provide effective, reliable flea control for
companion animals,” said Sarah Weston, Global Veterinary Services Manager at
Bayer Animal Health.

About the Flea Susceptibility Monitoring (FSM) program

The FSM is a large-scale international program based on a monitoring
methodology which utilises flea eggs collected from the field in the US,
Germany, UK, France and Australia. Egg collection is carried out by a network
of veterinarians and the samples analysed in four investigating laboratories
based in three countries. The FSM was set up in 1999 and to date has not
detected any reduced susceptibility to imidacloprid. A dedicated team of 15
people including independent experts in veterinary parasitology, entomology
and molecular biology, in addition to Bayer personnel, work together to
manage the FSM program.
