| evolution of picornaviridae: an examination of phylogenetic relationships and cophylogeny. | picornaviruses are responsible for some of the most common and debilitating illnesses affecting humans and animals worldwide. to extend our knowledge of the evolution of picornaviruses and their molecular epidemiology, phylogenetic relationships among 11 genera and the unassigned seal picornavirus type 1 were estimated from the conserved proteins 2c, 3c(pro), and 3d(pol). each gene was analyzed separately and as a combined dataset. different tree topologies were recovered from each gene. however ... | 2010 | 19835964 |
