Bioniche Chief Veterinary Scientific Officer Discusses Vaccine Against E. coli O157 at International Meat Industry Conference

PR Newswire (Canada)
BELLEVILLE, ON, June 13, 2011 /CNW/ -- - Bioniche has the world's
first commercially available cattle vaccine against an
Enterohaemorraghic E. coli (EHEC) - BELLEVILLE, ON, June 13, 2011
/CNW/ - Bioniche Life Sciences Inc. (TSX: BNC) (ASX: BNC), a
research-based, technology-driven Canadian biopharmaceutical
company, today announced that its Chief Veterinary Scientific
Officer, Dr. Dragan Rogan, was an invited speaker at the 56(th)
International Meat Industry Conference being held in Tara, Serbia.
Dr. Rogan's presentation was entitled, "Pre-slaughter intervention
by vaccination of cattle - new approach to reduce risk of meat
contamination by foodborne pathogens, and consequently reduce
incidence of human disease and economic burden". He described E.
coli O157, the central role of cattle in disseminating E. coli O157
in meat, produce, water and the environment, and the rationale for
the development and implementation of an efficacious pre-harvest
vaccination strategy using a fully licensed vaccine (Econiche(TM)).
He highlighted that an on-farm vaccination strategy is one of the
best methods to reduce the prevalence of E. coli O157 both within
its primary host - cattle - and in the general environment. E. coli
O157 is an Enterohaemorrhagic E. coli or EHEC. EHEC strains consist
of a subset of E. coli that have acquired virulence factors and are
pathogenic to humans. These are shiga toxin-producing E. coli that
can cause haemorrhagic colitis (HC) and haemolytic uremic syndrome
(HUS) in humans. Econiche(TM) has the potential to significantly
reduce the amount of E. coli O157 shed into the environment by beef
and dairy cattle. E. coli O157 does not cause illness in cattle,
but cattle are the primary reservoir for it. Vaccination of cattle
with Econiche(TM) can help reduce the risk of food and waterborne
contamination with E. coli O157. The Company has been actively
exploring opportunities to introduce Econiche(TM) to markets beyond
North America, where it has a full license in Canada and a pending
conditional license in the U.S. There is a significant amount
of international attention currently refocusing on the danger
presented by EHEC. A new strain - O104:H4 - was identified as the
causative organism of a massive outbreak in Germany in recent weeks
that sickened more than 3,000 people and caused 35 deaths.
"Although the Bioniche vaccine targets the O157 serotype of E.
coli, other serotypes causing human infection appear to have
similar attachment mechanisms to O157, and Bioniche believes that
Econiche(TM) may provide cross-protection against other serotypes,"
said Dr. Dragan Rogan, Chief Veterinary Scientific Officer at
Bioniche Life Sciences Inc. "Researchers at Bioniche are currently
working to confirm the extent to which such cross-protection may
exist." Bioniche, in collaboration with Dr. Brett Finlay,
University of British Columbia, and the Vaccine and Infectious
Disease Organization developed and fully licensed Econiche™ for use
in healthy cattle. The vaccine has been shown to reduce the
shedding of E. coli O157 in cattle. The vaccine targets the type
III secretory system (TTSS), which is essential for E. coli O157
attachment in the recto anal junction of cattle. Controlled
challenge studies demonstrate that vaccinating cattle with
Econiche™ results in: 1. 99.5% reduction in the number of bacteria
shed in feces; 2. 71% reduction in the proportion of animals
shedding; 3. 64% reduction in duration of shedding; and 4.
Reduction in the number of days that bacteria are shed in feces.
Econiche(TM) will be manufactured in the Company's newly completed
Animal Health and Food Safety Vaccine Manufacturing Centre in
Belleville, Ontario, currently undergoing validation and
commissioning. Full production in the new Centre is expected to
begin by the fall of 2011. About the 56(th) International Meat
Industry Conference The 56th International Meat Industry Conference
was organized by the Institute of meat Hygiene and Technology,
Belgrade. Its focus is meat and meat products - safety, culture,
development and quality of life. Conditions in primary production,
biotechnology in primary production and meat processing, transport
of animals and slaughtering, meat processing, sale of meat and meat
products, the customer role in meat and meat products safety as
well as safety and quality of meat and meat products are being
addressed. More About E. coli O157 The E. coli O157 organism causes
no disease in cattle, but cattle are the primary reservoir for it.
E. coli O157 can cause severe illness and can even be fatal when
ingested by humans from contaminated meat, vegetables, other food
products, or water. Human exposure and infection with E. coli O157
can result in serious health consequences, including abdominal pain
and severe bloody diarrhea. In severe cases, kidney damage can
occur and progress to serious complications and even death.
Lingering, long-term medical conditions can persist in individuals
exposed to the bacterium. These include post-infectious irritable
bowel syndrome (PI-IBS), reduced kidney function, diabetes,
hypertension and reactive arthritis. An estimated 100,000 cases of
human infection with the E. coli O157 organism are reported each
year in North America. Two to seven per cent of those people
develop haemolytic uremic syndrome (HUS), a disease characterized
by kidney failure. Five percent of HUS patients die, many of them
children and senior citizens, whose kidneys are more sensitive to
damage. In the recent German outbreak, twenty-five percent
developed HUS. Officials consider this outbreak to be the
third-largest involving E. coli in recent world history, and it is
the deadliest. Twelve people died in a 1996 Japanese outbreak that
reportedly made more than 9,000 people sick, and seven died in the
Walkerton, Ontario, tainted water outbreak in 2000. Beyond the
German outbreak, there have been a number of other recent outbreaks
associated with EHEC strains. U.S. outbreaks of E. coli O157 in
Oklahoma, Tennessee, Virginia, Louisiana and Texas have caused 30
illnesses and one death. Another O157 outbreak in Bristol, UK
caused 23 illnesses. An outbreak associated with E. coli O111 made
more than 20 people ill. About Bioniche Life Sciences Inc. Bioniche
