Acute and recurrent infection with herpes simplex virus in the mouse: a model for studying latency and recurrent disease. 1975

T J Hill, and H J Field, and W A Blyth

Nineteen recent isolated and three laboratory strains of herpes simplex virus types 1 and 2 were tested for their ability to produce clinical signs in mice following intradermal inoculation in the ear. All viruses produced erythema at the inoculation site; this was the most sensitive clinical sign of infection. Virus multiplication in the ear tissue was similar for both types 1 and 2 up to the fifth day after inoculation but type 2 viruses persisted for longer. Latent infection was demonstrated in cervical dorsal root ganglia. Type 1 viruses required a much higher dose than type 2 to produce neurological signs and death after intradermal inoculation but the difference was less after intracerebral inoculation. Erythema of the inoculated ear recurred sporadically during several months observation in about half the mice that survived intradermal infection with a selected type 1 isolate. The presence of virus in the ear tissue during such recurrences was confirmed by electron microscopy and isolation of infectious virus. The system of ear infection in the mouse is presented as a new model for studying neurovirulence, and latent and recurrent infection with herpes simplex virus.

D004890	Erythema	Redness of the skin produced by congestion of the capillaries. This condition may result from a variety of disease processes.	Erythemas
D005727	Ganglia, Spinal	Sensory ganglia located on the dorsal spinal roots within the vertebral column. The spinal ganglion cells are pseudounipolar. The single primary branch bifurcates sending a peripheral process to carry sensory information from the periphery and a central branch which relays that information to the spinal cord or brain.

D006561	Herpes Simplex	A group of acute infections caused by herpes simplex virus type 1 or type 2 that is characterized by the development of one or more small fluid-filled vesicles with a raised erythematous base on the skin or mucous membrane. It occurs as a primary infection or recurs due to a reactivation of a latent infection. (Dorland, 27th ed.)	Herpes Simplex Virus Infection
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012867	Skin	The outer covering of the body that protects it from the environment. It is composed of the DERMIS and the EPIDERMIS.
D014774	Virulence	The degree of pathogenicity within a group or species of microorganisms or viruses as indicated by case fatality rates and/or the ability of the organism to invade the tissues of the host. The pathogenic capacity of an organism is determined by its VIRULENCE FACTORS.	Pathogenicity
