They possess a circular single-stranded DNA genome encapsidated in twinned icosahedral virus
particles (Rojas et al., 2005).
The human parvovirus B19 (B19V), a member of the Erythroparvovirus genus (Parvoviridae family), is a small, non-enveloped icosahedral virus
composed of two structural proteins VP1 (83kDa) and VP2 (58kDa) surrounding a linear single-stranded DNA genome of approximately 5.6 Kb.
HPVB19 is the first known human virus in the Parvoviridae family, genus Erythroparvovirus, which is a nonenveloped, icosahedral virus
containing a single-stranded linear DNA genome .
BTV is an icosahedral virus
(80 nm in diameter) with a 10- segmented dsRNA genome (Mellor et al.
In most icosahedral virus
reconstructions from cryoEM, the signal is improved and the noise reduced by imposing icosahedral symmetry on the image data after refinement.

Their topics include producing and purifying viruses for structural studies, the X-ray crystallography of virus capsids, the evolution of viral capsid structures, mechanisms of icosahedral virus
assembly, attachment and entry, developing anti-HIV drugs, and viral vectors for gene delivery.
Other subjects covered include the memory behavior of emerging multi-core workloads, using graphics processors to accelerate the solution of out-of-core linear systems, and automating 3D reconstruction of icosahedral virus
structure with condensed graphs.
They cover, among other topics: radical enzymes in anaerobes, the structural and functional role of RNA in icosahedral virus
assembly, virulence genes in the dimorphic fungi, the adaptive mutation controversy, and multilocus sequence typing of bacteria.
