Cattle Engineered to Lack BSE-
Causing Proteins

An international team of researchers from the
United States and Japan has genetically engineered
several cattle to be free from prions, the proteins
associated with bovine spongiform encephalopathy. The
findings, published in the online journal Nature
Biotechnology, are leading to speculation that it may be
possible to make animals immune to the disease.
In a post-mortem study, research results showed
that after scientists "knocked out" the gene responsible
for making prions, animals did not succumb to BSE when
exposed to the bad prions associated with the disease.
However, it may be a few years before other animals in
the study demonstrate similar immunity to B SE.
"This could have some promising applications," Joe
Schuele, spokesman for the National Cattlemen's Beef
Association, told "However, the
safeguards we have in place in the United States have
eliminated BSE as a human health risk, and should have
us on track to completely eradicate BSE well before
this technology will be approved for any widespread
practical use."
Paul Clayton, senior vice president of export
services at the U.S. Meat Export Federation, told that it's too early to tell how the study
would affect access to foreign markets, since any
commercial applications of the research presumably lie
in the distant future.
"Also, since this is biotechnology, we may
encounter other access concerns," he said.
"These cattle can help in the exploration and
improved understanding of how prions function and cause
disease, especially with relation to bovine spongiform
encephalopathy," Edward B. Knipling, administrator of
USDA's Agricultural Research Service, indicated in a
press release. "In particular, cattle lacking the gene that
produces prions can help scientists test the resistance to
prion propagation, not only in the laboratory, but in live
animals as well."

Florida Department of
Agriculture and Consumer
Services Continues
Investigation Into Horse Virus

Florida Agriculture and Consumer Services
Commissioner Charles Bronson says the department's
Division ofAnimal Industry is continuing the investigation
into the presence of Equine Herpesvirus- type 1 (EHV-
1) in several areas of the state including Wellington,
Jupiter and the Ocala area. EHV-1 can be a serious
disease of horses and the virus can spread through the
air from the respiratory route of affected horses.
Transmission can also occur through contaminated
equipment, clothing and hands.
So far, seven horses have tested positive for the
virus through lab tests. All confirmed cases are under
Here is a chronology of events:
Five horses imported from Europe were brought
to Florida from the New York animal import station, a
quarantine station for imported horses; three more horses
were picked up en route in Huntington, N.Y and one in
Darlington, Maryland. When the truck arrived on
November 29' in Wellington, Florida, one of the horses
from the import station was ill. That horse is now
recovering but two horses that were stabled with the
index horse at the original facility became ill and died. A
lab test on one of those horses confirmed EHV-1. The
facility, J N and Company is currently under state
quarantine and the horses are being closely monitored.
No horses are allowed to enter or leave the premises.
The Maryland horse had been transported to
another Wellington location, Southfields Training facility,
and died on December 2nd. While no lab test was done,
because of its exposure to the disease, the Southfields
facility voluntarily restricted all movement of horses. Late
today, a lab test confirmed a positive case within that
facility at the Palm Beach Equine Sports Complex, which
is part of the Southfields Training facility. There is a
second suspect case there awaiting lab test confirmation.
The Department is also placing this facility under

A horse that was exposed to the virus during the
shipment into Florida was treated at the Palm Beach
Equine Clinic and is believed to have been a possible
link to the horse in Ocala, which was at the clinic at the
same time. The Ocala horse has tested positive for EHV-
1 and was transported to Ocala on December 11th. The
horse was ill when it arrived and was immediately isolated
from all other horses at the Ocala location, Tuxedo Farms.
The horse continues to be isolated and a portion of that
facility is also under quarantine.

The Palm Beach Equine Clinic indicated it is
contacting the owners of all horses that were there at the
same time as the index horse to make them aware of the
situation and find out if any of the horses are exhibiting
any signs ofEHV- 1. So far the department has received
no reports of any other horses that were at the clinic
showing disease signs.

Ahorse atPinehurst Stables, in Jupiter, Florida has
also been reported with neurological symptoms of the
disease and a sample has been submitted for a lab test.

The Division ofAnimal Industry is working closely
with veterinarians and equine facilities in the impacted
locations to monitor the animals and assist with testing.

Owners with sick horses should contact their private
veterinarian to examine and treat their horses.
Veterinarians suspecting EHV-1 with neurological signs
are advised to contact state officials and follow protocols
for collecting and submitting appropriate samples for
laboratory diagnosis.

Horse owners in the impacted areas are being asked
to follow biosecurity measures until the virus is controlled.
The measures are:

Have temperatures taken a minimum of twice
daily, with a temperature log being maintained on each
horse. Horses with fevers >101.9 or >1 degree above
their normal temperature should be reported to the
stable's veterinarian. The horse should be isolated and
EHV-1 samples should be taken by the stable

Limiting admittance of people into the barn area
to only necessary personnel. When entering or exiting a
stable or barn use foot baths to disinfecting outer foot
wear and wash hands.

Washing hands with soap and water or using a
dry disinfectant after handling each horse.

Minimizing the use of shared equipment.
Equipment such as water buckets, lead ropes, grooming
equipment, etc. should not be shared between horses.
These items should be labeled as belonging to an
individual horse. Other equipment such as twitches,
shovels, forks and bits should be disinfected daily and
between each use.

Care should be taken when filling water buckets
and feed troughs. Neither the hose nor the feed scoop
should have contact with an individual horse's bucket or

Multi-dose oral medications should not be
shared between horses.

Any additional biosecurity precautions the stable
veterinarian or stable manager recommend.
