Which of the following disease is caused by Orthopoxvirus?
Smallpox is caused by variola virus, genus Orthopoxvirus. Other members of this genus that can infect humans are vaccinia virus, monkeypox virus, and cowpox virus. In 1980, the World Health Organization officially declared the worldwide eradication of smallpox.
What is Horsepox?
Definition of horsepox : a virus disease of horses related to cowpox and marked by a vesiculopustular eruption of the skin especially on the pasterns and sometimes by a vesiculopapular inflammation of the buccal mucosa. — called also equine variola.
What is variolation in immunology?
variolation, obsolete method of immunizing patients against smallpox by infecting them with substance from the pustules of patients with a mild form of the disease (variola minor). The disease then usually occurs in a less-dangerous form than when contracted naturally.
What is cowpox virus?
Cowpox is a skin disease caused by a virus belonging to the Orthopoxvirus genus. Sporadic human cases of cowpox have been reported in Europe, mostly linked to handling of infected animal, usually rodents and cats. Human infection results from direct contact with an infected animal.
Is Covid an RNA virus?
COVID-19, short for “coronavirus disease 2019,” is caused by the novel coronavirus SARS-CoV-2. Like many other viruses, SARS-CoV-2 is an RNA virus. This means that, unlike in humans and other mammals, the genetic material for SARS-CoV-2 is encoded in ribonucleic acid (RNA).
What type of microbe is variola virus?
The variola virus is a large, brick-shaped, double-stranded DNA virus that serologically cross-reacts with other members of the poxvirus family, including ectromelia, cowpox, monkeypox, vaccinia, and camelpox. Unlike other DNA viruses, the variola virus multiplies in the cytoplasm of parasitized host cells.
Is horsepox extinct?
Horsepox virus is believed to have become extinct through some natural process. No known horsepox outbreaks have been reported since 1976, at which time the US Department of Agriculture obtained the viral sample used for the sequence published in 2006 in the Journal of Virology – crucial recreating the virus.
What is variolation in biology?
Variolation: The old practice of inoculating someone with the virus of smallpox to produce immunity to the disease.
What is variolation and what is its purpose?
Variolation was the method of inoculation first used to immunize individuals against smallpox (Variola) with material taken from a patient or a recently variolated individual, in the hope that a mild, but protective, infection would result.
