Re: Please Read!!!!!! New Parvo Strain Hits West Michigan
Parvo 2c has been suspected as the cause of death for at least three
adult canines in Kent County and surrounding areas. Two of the three
dogs had a known previous vaccine history and tested positive on the
Idexx Snap Parvo Test. The most current information on Parvo 2c from
the vaccine/shelter medicine specialists around the country is as
follows:
Disease: Parvo 2c is a highly virulent strain of the parvo virus that
is extremely fatal in puppies and adult dogs. This strain of parvo
attacks the circulatory organs approximately 24 hours before
attacking the gastrointestinal tract. Therefore, by the time a dog is
presented for lethargy, vomiting, and diarrhea it is generally too
late.
Diagnosis: Parvo 2c is detectable on the Idexx Snap Test, but it has
been showing as a weak positive on many tests. Viral isolation is the
best way to confirm the diagnosis, but it is not going to assist with
diagnosis upon presentation.
Treatment: Conservative treatment with supportive care has been
rarely successful. Plasma transfusions from recovered dogs have shown
to yield the best treatment success at around 64% survival rate.
Prevention: Schering-Plough (SP) and Intervet vaccinations have been
proven to be 100% effective in preventing this strain of parvo. If
you have any questions in regards to SP vaccinations please call 1-
800-224-5318 (SP technical support). Fort Dodge vaccines were
effective in less than 90% of the tested dogs/puppies, Pfizer was
less than 70% effective in preventing disease, and Merial was less
than 50% effective. This data was obtained from an independent
source, and at this time the only published data is an article from
Schering-Plough (S/P).
Cleaning Protocols: There are only two products that kill this virus
with a ten minute contact time. Trifectant and bleach (1/2 cup/gallon
dilution) will successfully kill Parvo 2c. All other products that
claim to kill parvo are not effective per Dr. Hall (Vaccination/
Shelter Specialist at SP) !!!!!!
Prognosis: The prognosis is extremely poor. Most puppies or dogs die
acutely from the cardiac components of the disease process. If GI
signs are present, the disease has progressed and is most likely
fatal.
Please feel free to call me with any questions (616) 791-8218. Over
seven veterinary clinics have seen this type of disease locally. The
citizens of Kent County need to be aware of the risk associated with
this disease. Please inform your clients and protect the canines in
your area.
