New Deadly Strain of Parvo Responsible for Canine Deaths Despite Vaccinations *Permission to re-post!
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 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 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).
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 don’t hesitate 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.
