Herpesviridae A diverse family of DNA viruses with characteristic morphology. Classification is based formally on genetic content. The virion is 100-200nm in diameter. Buoyant density (CsCl): 1.20-1.29g/ml. Consists of four structural components: (1) the core, a protein fibrillar spool on which the DNA is wrapped; (2) the capsid, 100-110nm in diameter, composed of 12 pentameric and 150 hexameric capsomeres arranged with icosahedral symmetry; (3) the tegument, an amorphous asymmetrical layer between the capsid and (4) the envelope, a bilayer membrane with surface projections. The capsomeres are hexagonal in cross-section and have a hollow running down half their length. The genome consists of linear double-stranded DNA 124-235kb in length, depending on the species, with both terminal reiterations and internal repetitions. G+C content 32-75%. There are more than 20 structural polypeptides, mol. wt. 12000-220000. Lipid content is variable and located in the envelope. Carbohydrate is covalently linked to envelope proteins. After attachment and penetration the genome reaches the nucleus where the viral DNA is transcribed. mRNA passes to the cytoplasm for translation. Virus-specific enzymes and other factors involved in replication and DNA metabolism are induced. Viral DNA is replicated in the nucleus and immature nucleocapsids are formed which bud through the inner lamella of the nuclear membrane, acquiring an envelope and becoming infective. Virus particles accumulate between the inner and outer lamellae of the nuclear membrane and in the cysternae of the endoplasmic reticu-lum from where they are released to the cell surface. Margination of chromatin and intranuclear inclusion bodies are characteristic of herpesvirus-infected cells. Production of infectious progeny virus is accompanied by destruction of the infected cell. All herpesviruses studied so far are also able to remain latent in their host cells. In this case, the genome becomes closed-circular and only a small subset of viral genes is expressed. There are many species and they are found in most eukaryotic hosts which have been examined in detail, from humans to oysters. Some species are cell-associated and free infective units are scarce. A few are oncogenic. Many cause mild or silent infections in their natural hosts but severe disease in others. They replicate with CPE in cell cultures and some species produce pocks on the CAM. There are three subfamilies: Alpha-herpesvirinae, Betaherpesvirinae and Gamma-herpesvirinae. The emphasis in defining the subfamilies and genera, and the species assigned to them, is placed on the DNA structure and sequence data.

herpes zoster An acute self-limited infectious disease (known also as shingles or zona) caused by reactivation of latent VZV (Human herpesvirus 3) infection. It occurs frequently in persons who are severely immunocompromised, e.g. as a result of HIV infection, and may be fatal, and in up to 20% of normal immunocom-petent persons over 45 years of age. Symptoms include vesicular lesions similar to those of varicella which usually follow an anatomical route around the body along the dorsal route ganglia as the virus spreads from cells along the neurons to epithelial cells of the skin. The condition may be painful, and although the lesions disappear in a few weeks a chronic debilitating pain (post-herpetic neuralgia) often begins about a month after the onset of skin lesions and may persist for months.
