Thunderpony, in regard to the distemper vaccine that you claim is what caused canine parvovirus originally, I wrote to the ultimate authority, (below) I sincerely hope that this will ease some of the worries you have regarding vaccinating dogs for fatal, deadly diseases. I hope additionally that you have vaccinated any puppies you have had against this dreadful disease. Progard, by Intervet, has been proven in university studies to override maternal immunity, and be very effective in young puppies, with a low incidence of vaccine reaction. If you have not had these diseases, (or are younger), you have not had the horrific experience of watching puppies die from such disease. I would much rather vaccinate...than bury them young. Shalom, Syd Harmon Rogers DVM DABVP Clinical Associate Professor Director, Veterinary Teaching Hospital, Pullman, Wa Hi Syd, Itâ??s great to hear from you again. Hope all is going well for you and that ill dogs are a rarity. Please say hello to Brenda for me. Canine distemper is a markedly different virus from parvovirus. It is not possible for canine distemper virus or canine distemper vaccine to create canine parvovirus. It is possible that canine parvovirus might have developed from a mutation of feline distemper. Feline distemper (also called feline panleucopenia) is caused by a parvovirus very similar to canine parvovirus. Feline distemper virus is completely different from canine distemper virus. Below is a quote from an authoritative text, A Concise Review of Veterinary Biology, by Carter, Wise, and Flores. IVIS electronic publishing last updated Dec 2004. Best, Harmon Canine Parvovirus Disease (Canine parvovirus enteritis) Cause Canine parvovirus type 2, which is closely related to feline panleukopenia virus, mink enteritis virus and raccoon enteritis virus. The single-stranded genome (5124 nucleotides in length) of these viruses varies less than 2% in sequence analysis. Variants with minor changes in nucleotide sequences have been reported. It appears that canine parvovirus (CPV) differs from the feline virus in two amino acids in the capsid protein VP2. It is thought that CPV originated from FLPV (Feline Panleucopenia Virus) by mutations in these amino acids in the late 1970â??s. These changes enable CPV to replicate in dogs. ____________________________________ From: Elsyd1@xxxxxxx [mailto:Elsyd1@xxxxxxx] Sent: Monday, January 29, 2007 9:44 AM To: Rogers, Harmon Subject: Hello from Syd SYD MAILBERG 23910 SE 276TH ST MAPLE VALLEY, WA 98038 ============================================================================ POST is Copyrighted 2006.
