Species

The genus consists of the following two species: [2]

Structure

Viruses in Scutavirus are enveloped, with icosahedral, spherical to pleomorphic, and round geometries, and T=16 symmetry. The diameter is around 150-200 nm. Genomes are linear and non-segmented. [1]

Life cycle

Viral replication is nuclear, and is lysogenic. Entry into the host cell is achieved by attachment of the viral gB, gC, gD and gH proteins to host receptors, which mediates endocytosis. Replication follows the dsDNA bidirectional replication model. DNA-templated transcription, with some alternative splicing mechanism is the method of transcription. The virus exits the host cell by nuclear egress, and budding. Turtles and tortoises serve as the natural host. [1]

Roseolovirus is a genus of viruses in the order Herpesvirales, in the family Herpesviridae, in the subfamily Betaherpesvirinae. Humans serve as natural hosts. There are currently three species in this genus including the type species Human betaherpesvirus 6A. Diseases associated with this genus include: HHV-6: sixth disease ; HHV-7: symptoms analog to the 'sixth disease'.

Nanoviridae is a family of viruses. Plants serve as natural hosts. There are currently 12 species in this family, divided among 2 genera and one unassigned species. Diseases associated with this family include: stunting. Their name is derived from the Greek word νᾶνος, because of their small genome and their stunting effect on infected plants.

Mardivirus is a genus of viruses in the order Herpesvirales, in the family Herpesviridae, in the subfamily Alphaherpesvirinae. Chickens, turkeys, and quail serve as natural hosts. There are currently five species in this genus including the type species Gallid herpesvirus 2. Diseases associated with this genus include: Marek's disease, which causes asymmetric paralysis of one or more limbs, neurological symptoms, and development of multiple lymphomas that manifest as solid tumors. Gallid herpesvirus 2 is the only one of these viruses known to be pathogenic and due to the antigenic similarity between the three viruses the other two have been used to vaccinate against Marek's disease. These viruses have double stranded DNA genomes with no RNA intermediate.

<i>Alphaherpesvirinae</i> Subfamily of viruses

Alphaherpesvirinae is a subfamily of viruses in the family Herpesviridae, primarily distinguished by reproducing more quickly than other subfamilies in the Herpesviridae. In animal virology the most important herpesviruses belong to the Alphaherpesvirinae. Pseudorabies virus is the causative agent of Aujeszky's disease in pigs and Bovine herpesvirus 1 is the causative agent of bovine infectious rhinotracheitis and pustular vulvovaginitis. Mammals serve as natural hosts. There are currently 42 species in this subfamily, divided among 5 genera with one species unassigned to a genus. Diseases associated with this subfamily include: HHV-1 and HHV-2: skin vesicles or mucosal ulcers, rarely encephalitis and meningitis, HHV-3: chickenpox (varicella) and shingles, GaHV-2: Marek's disease.

Varicellovirus (var′i-sel′ō-vi′rŭs) is a genus of viruses belonging to subfamily Alphaherpesvirinae, a member of family Herpesviridae. Humans and mammals serve as natural hosts.
