Classification

This is a description of a vertebrate virus at the species level.

ICTVdB Virus Code: 00.031.1.02.013. Virus accession number: 31102013.

Name, Synonyms and Lineage

The taxon has the accepted ICTV name.

Alternative name: Gazelle herpesvirus 1. ICTV approved acronym: EHV-9. Acronym(s): GHV-1. Virus is an ICTV approved species of the genus 00.031.1.02. Varicellovirus; subfamily 00.031.1. Alphaherpesvirinae in the family 00.031. Herpesviridae.

Virion Properties

Morphology

Virions consist of an envelope, a tegument, a capsid, and a core. During their life cycle, virions produce extracellular particles. Virus capsid is enveloped. Virions are spherical. Capsid/nucleocapsid is round and exhibits icosahedral symmetry. The capsid is isometric.

Nucleic Acid

The genome is not segmented and contains a single molecule of linear double-stranded DNA. Sequence can be accessed from DNA Data Bank of Japan is partially sequenced. Sequenced genome has the accession number(s)
[D49800]for the gB homologue; [D85905] for the gG homologue.

Biological Properties

Natural Host

Virus infects during its life cycle a single type of vertebrate host.
Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Animalia.

Kingdom Animalia
Phylum Chordata.

Phylum Vertebrata
Subphylum Vertebrata; Class Mammalia.

Class Mammalia Order Artiodactyla;
Family Bovidae: Subfamily Antilopinae; virus infects Genus Gazella thomsonii.

General Symptoms in Animals Infection can affect the nervous system and dermis, mucosa or epithelium. General symptoms include lesions. Lesions are found in nerve tissue and brain. Signs and symptoms include epizootic encephalitis.

Severity and Occurrence of Disease

Host: Although disease expression is dependent on dose, infection is usually acute. The infection is clinically expressed. Signs and symptoms may vary, but are usually severe and persist. In naturally infected hosts morbidity rate may be as high as 90 %; mortality rate may approach 10 %.

Diagnostic Hosts

For virus isolation the most commonly used cell lines or tissue cultures are MDBK. Diagnostic host: insusceptible host species PK-15. Virus has been propagated in cell culture.

Maintenance and Propagation Hosts

Cell lines or tissue cultures used for propagating virus are MDBK.

Assay Hosts

Host: Cells used for assaying virus MDBK.
