Ectromelia virus
Ectromelia virus A member of the poxvirus family which is a highly virulent natural pathogen of mice that causes mousepox, a severe disease with high mortality rate in mice but does not infect humans. The complete genome sequence of ectromelia virus is known.
RELATED TERMS--------------------------------------
Family
1. A group of individuals related by blood or marriage or by a feeling of closeness. 2. A biological classification of related plants or animals that is a division below the order and above the genus. 3. A group of genes related in structure and in function that descended from an ancestral gene. 4. A group of gene products similarly related in structure and function and of shared genetic descent. 5. Parents and their children. The most fundamental social group in humans.
Natural
Not human-induced or manmade.
Pathogen
A disease causing organism. It can be viral, bacterial, fungal or other items such as prions... The seriousness of the disease is measured as its pathogenicity. How likely/contagious it is, is called virulence.
Disease
Illness or sickness often characterized by typical patient problems (symptoms) and physical findings (signs). Disruption sequence: The events that occur when a fetus that is developing normally is subjected to a destructive agent such as the rubella (German measles) virus.
Mortality
Statistics on deaths within a population based on official death certificates, usually showing numbers of deaths by age, sex and cause.
Genome
The complete genetic material of an organism.
Virus
Ultramicroscopic infectious agent that replicates itself only within cells of living hosts; many are pathogenic; a piece of nucleic acid (DNA or RNA) wrapped in a thin coat of protein.
SIMILAR TERMS--------------------------------------
Ectrodactyly
The congenital absence of all or part of one or more fingers or toes. The term ectrodactyly has been applied to a variety of malformations of the fingers or toes. It is probably best reserved for: transverse terminal aphalangia (absence of the last bone in the finger or toe), adactylia (total absence of a finger or toes), or acheiria (total absence of one or both hands).
Ectropion

PREVIOUS AND NEXT TERMS--------------------------------------

Ectoparasite
A parasite that lives on or in the skin but not within the body. Fleas and lice are ectoparasites. Infestation with an ectoparasite is called an ectoparasitosis.
Ectoparasitosis
Infestation with an ectoparasite, a parasite that lives on or in the skin. The four major ectoparasitoses are pediculosis, scabies, cutaneous larva migrans and tungiasis (sand-flea disease).
Ectopia cordis
A type of birth defect in the heart is abnormally located. In ectopia cordis, the heart usually protrudes outside the chest.

Ectromelia virus
Eczema vaccinatum
A common concern with smallpox vaccination involving the implantation of the vaccinia virus from the vaccination into the skin of a person with eczema (atopic dermatitis), sometimes with a fatal outcome. Disrupted skin permits viral implantation. Once the virus is implanted, it spreads from cell to cell producing extensive lesions. The skin lesions appear identical to a primary smallpox vaccination. Confluent lesions often cover the entire face, the crook of the elbow in the antecubital fossa, and behind the knee in the popliteal fossa. Viremia (viral spread through the bloodstream) may also occur allowing for the spread of virus to other parts of the body, including skin that is not affected by eczema. Bacterial and fungal invasion may occur as a late stage of untreated eczema vaccinatum.
Eczema, allergic contact
Also called allergic contact dermatitis, this is a red, itchy, weepy reaction where the skin has come into contact with a substance that the immune system recognizes as foreign, such as poison ivy or certain preservatives in creams and lotions.
Eczema, contact
A localized reaction that includes redness, itching, and burning where the skin has come into contact with an allergen (an allergy-causing substance) or with an irritant such as an acid, a cleaning agent or another chemical.
Eczema, dyshidrotic
Irritation of the skin on the palms of hands and soles of the feet characterized by clear, deep blisters that itch and burn.
Eczema, nummular
Coin-shaped patches of irritated skin-most common on the arms, back, buttocks, and lower legs that may be crusted, scaling, and extremely itchy.
