Nowadays one of the major challenges facing herders, dog owners, or working dog training centers is canine parvovirus (CPV-2). The virus has split into several types over the years since it discovered and resulted to genetic and amino acid changes that threaten a wide range of carnivorous around the world. The best way to avoiding the consequences of this disease is vaccination. This study were designed, due to the lack of sufficient studies on the distribution and prevalence of different types of this virus, which may be a prominent cause of vaccine errors, also because of high involvement of Iranian dogs with CPV. Molecular study and phylogenetic comparison of Iranian types compared to other types through the world showed that the dominant type of CPV-2 existed in Iran is CPV-2a with a prevalence of 24% and genetic differences in several points of VP2 gene with other types. We are probably facing to a new version of this virus in our country. In addition, based on the drawn phylogenetic tree, it was found that Iranian isolates on the other side have a relatively high topological difference compared to the origin types and conventional vaccines strain, which supports the initial hypothesis of this study.
