Abstract
The family Poxviridae is a large and diverse family of double-stranded DNA viruses with ubiquitous distribution. Poxviruses parasit-ize invertebrates, birds, reptiles and mam-mals suggesting that the family Poxviridae is an ancient virus family. The genomes are lin-ear and encode a large complement of genes. Essential viral functions are clustered in the central region of the genome and a core group of critical genes are conserved among all pox-viruses. In contrast, species-specific genes, nec-essary for host infection and virus virulence, are maintained near the termini. The success of the poxvirus family members is based on the acquisition of cellular genes that have evolved under viral/host selection to permit the virus to modulate the host immune response.
