Herpes simplex virus,coloured transmission electron micrograph (TEM). The virus has an icosahedral capsid (protein coat,yellow/light green,centre left) surrounding a core of DNA (deoxyribonucleic acid) genetic material. The membrane envelope surrounds the capsid and is usually continuous with it,but it has broken away here,giving the virus a "fried-egg" appearance. Herpes simplex is one of the most common viral pathogens in humans. It causes inflammation of the skin and mucous membranes,characterized by fluid-filled blisters. Magnification unknown | |
