Smallpox belongs to the
Orthopox virus genus. Poxviruses are very large,
brick-shaped viruses about 300 x 200 nm (the size of small
bacteria). They have a complex internal structure - a
large double-stranded DNA genome (about 200 kbp in size)
is enclosed within a core that is flanked by 2 lateral
bodies. The surface of the virus particle is covered with
filamentous protein components, so that the particles have
the appearance of a ball of knitting wool. The entire
particle is enclosed in an envelope derived from the host
cell membranes. |
