Panleukopenia Virus

Decent Essays
Many before have questioned the relationships between Feline Panleukopenia Virus (FPLV) and Canine Parvovirus (CPV), or whether there are any at all. Multiple different studies have been conducted to determine whether there are any links amongst CPV and FPLV. The studies being reviewed will touch on the following: the evolution of CPV, the connection between hosts, the genetics and the antigenic characteristics among them. “CPV and FPLV are known to be closely related viruses genetically and biologically…” (Horiuchi, Yamaguchi…,1998). There are a few other viruses compared but the CPV and FPLV have the most similarities. Panleukopenia virus in cats infects domestic as well as feral, is a fast- acting, highly contagious viral infection that…show more content…
The first up being about the evolution of CPV theorized that CPV, FPLV, and MEV are all similar parvoviruses and can therefore share similar hosts. To back up their thesis, the authors of the article, Differences in the Evolutionary Pattern of Feline Panleukopenia Virus and Canine Parvovirus state that, “when the entire gene regions are compared, …thereby leading to the interpretation that the gene is changing in a way that is consistent with the neutral theory of molecular evolution, even though positive selection may be operating at least on specific regions of the gene. FPLV appeared to be in evolutionary stasis, which agrees with the idea that a CPV ancestor arose from FPLV or an FPV-like virus as a result of random genetic mutations (Horiuchi, Yamaguchi… 1996).” In short, this article states that there is an evolutionary relationship between CPV and FPLV in that CPV is an ancestor or evolved form of
