Pathogenic Virus
A viral disease (or viral infection) occurs when an organism's body is invaded by pathogenic viruses, and infectious virus particles (virions) attach to and enter susceptible cells. Structural Characteristics Basic structural characteristics, such as genome type, virion shape and replication site, generally share the same features among virus species within the same family. * Double-stranded DNA families: three are non-enveloped (''Adenoviridae'', ''Papillomaviridae'' and ''Polyomaviridae'') and two are enveloped (''Herpesviridae'' and ''Poxviridae''). All of the non-enveloped families have icosahedral capsids. * Partly double-stranded DNA viruses: ''Hepadnaviridae''. These viruses are enveloped. * One family of single-stranded DNA viruses infects humans: ''Parvoviridae''. These viruses are non-enveloped. * Positive single-stranded RNA families: three non-enveloped (''Astroviridae'', ''Caliciviridae'' and ''Picornaviridae'') and four enveloped (''Coronaviridae'', ''Flaviviridae' ...

Bromoviridae
''Bromoviridae'' is a family of viruses. Plants serve as natural hosts. There are six genera in the family. Taxonomy The following genera are assigned to the family: * ''Alfamovirus'' * ''Anulavirus'' * ''Bromovirus'' * '' Cucumovirus'' * ''Ilarvirus'' * ''Oleavirus ''Oleavirus'' is a genus of viruses, in the family '' Bromoviridae''. Olive trees serve as natural hosts. There is only one species in this genus: ''Olive latent virus 2''. Structure Viruses in the genus ''Oleavirus'' are non-enveloped, with i ...'' Structure Viruses in the family ''Bromoviridae'' are non-enveloped, with icosahedral and bacilliform geometries. The diameter is around 26-35 nm. Genomes are linear and segmented, tripartite. Life cycle Viral replication is cytoplasmic, and is lysogenic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded rna virus transcription, using the interna ...

''Anulavirus'' is a genus of viruses, in the family '' Bromoviridae''. Pelargonium ''Pelargonium'' () is a genus of flowering plants that includes about 280 species of perennials, succulents, and shrubs, commonly called geraniums, pelargoniums, or storksbills. '' Geranium'' is also the botanical name and common name of a separ ... serve as natural hosts. There are two species in this genus. Taxonomy The following species are assigned to the genus: * '' Amazon lily mild mottle virus'' * '' Pelargonium zonate spot virus'' Structure Viruses in the genus ''Anulavirus'' have icosahedral and Quasi-spherical geometries, and T=3 symmetry. The diameter is around 25-35 nm. Genomes are linear and segmented, tripartite. Life cycle Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell.
