Herpes Simplex Virus Pathogenesis

Hsv are of two types. Pathogenesis of herpes virus.

Primary infection man is the only natural host to hsv the virus is spread by contact the usual site for the implantation is skin or mucous membrane.

Herpes simplex virus pathogenesis. Following exposure the primary infection of hsv is established at the site of contact. Hsv is large enveloped icosahedral virus. Both viruses have the capacity to invade and replicate in the cns and the capacity to establish a latent infection in dorsal root ganglia roizman and pellett 2001.

Herpes simplex viruses are ubiquitous host adapted pathogens that cause a wide variety of disease states. It is also known as human herpesvirus. The vesicle fluid contains multinucleated giant cells and eosinophilic intra nuclear inclusion with inflammatory cells and cellular debris.

The intermediate and basal undergo acantholysis leading to vesicle formation. The naked virion measures about 100 nm. The herpes simplex virus is a contagious virus that can be transmitted from person to person through direct contact.

The diameter of a complete particle is 120 200 nm. Pathogenesis of herpes simplex viruses infection. This single review article can provide the entire knowledge about the pathogenesis its interesting property of latency and clinical features of hsv infection under one tree.

Hsv 1 and hsv 2 exhibit two unique biologic properties that influence pathogenesis and subsequent human disease. The primary mode of entry is through the skin oral mucosa or eyes. Herpes simplex virus the envelope which surrounds the naked particle is partly nuclear membrane derived partly virally coded with glycoprotein spikes.

It may result into a vesicle formation under the layer of keratinized squamous epithelial cells. Here the viral envelope is fused with the cellular membranes of the skin and mucous membranes and hsv dna. The pathogenesis of herpes simplex herpetic infection the virus of herpes simplex penetrates into the human body through the mucous membranes damaged skin in the cells of the cornermal epithelium of the skin there are no receptors to the virus.

Human is only natural host for hsv. Herpes simplex virus is a highly contagious human pathogen that has widespread infections in the oro facial region which is associated with hsv 1. Structure and genome mode of transmission pathogenesis infection laboratory diagnosis and treatment structure and genome.

Herpes simplex virus type 1 hsv 1 and type 2 hsv 2. Children will often contract hsv 1 from early contact with an infected adult.
