Thermo-Efficient Strains of Variola Major Virus
Journal of General Virology, 1967 Thermo-efficient and thermo-sensitive mutants of pox viruses are obtained, without the aid of mutagens, only with difficulty. Kirn and his colleagues (1, 2) have described both a thermo-sensitive and a thermo-efficient mutant of vaccinia virus. This note reports the derivation and properties of two thermo-efficient strains of variola major virus.

An Antigenically Atypical Strain of Variola Virus
Journal of General Virology, 1976 The Kuwait-5-67 strain of variola virus, although indistinguishable from variola virus in its other properties, behaved atypically in immuno-diffusion tests with antivaccinia serum. The precipitation line pattern produced was similar to that of cowpox virus but lacked one of the main precipitation bands given by all other strains of variola, alastrim ...

Should Remaining Stockpiles of Smallpox Virus (Variola) Be Destroyed?
Emerging Infectious Diseases, 2011 In 2011, the World Health Organization will recommend the fate of existing smallpox stockpiles, but circumstances have changed since the complete destruction of these cultures was first proposed.

Viruses, 2010 The absence of herd immunity to orthopoxviruses and the concern that variola or monkeypox viruses could be used for bioterroristic activities has stimulated the development of therapeutics and safer prophylactics.

Smallpox in the Post-Eradication Era
Viruses, 2020 Widespread vaccination programmes led to the global eradication of smallpox, which was certified by the World Health Organisation (WHO), and, since 1978, there has been no case of smallpox anywhere in the world.

Untersuchungen am Virus der Variola-Vaccine
Zeitschrift für Naturforschung B, 1955 Die nach Chabaud-Fixierung und Pepsinbehandlung in der Elementarkörper-Membran zurückbleibenden Desoxyribonucleoproteide des Vaccine-Virus liegen bei den am häufigsten beobachteten Formen peripher von der im intakten Elementarkörper sichtbaren zentralen Verdichtung und sind nicht mit ihr identisch.

Strategies for the Modification of Vaccinia Virus towards a Better Vaccine Vector
ZoonosesVaccinia virus (VACV) confers cross-protective immunity against variola virus, the causative agent of smallpox, and has therefore been extensively exploited as a preventive vaccine.

Untersuchungen am Virus der Variola-Vaccine
Zeitschrift für Naturforschung B, 1954 Der nach Pepsinhydrolyse von Vaccine-Elementarkörpern freigelegte Innenkörper kann nach Depolymerisierung der DNS durch Desoxyribonuclease mit einer zweiten Pepsinbehandlung fast völlig abgebaut werden. Er verhält sich in dieser Hinsicht wie die Kerne von Bakterien und höheren Zellen und scheint neben DNS-Histon auch noch andere Proteine zu enthalten ...

PLoS Pathogens, 2015 Orthopoxviruses (OPV), including variola, vaccinia, monkeypox, cowpox and ectromelia viruses cause acute infections in their hosts. With the exception of variola virus (VARV), the etiological agent of smallpox, other OPV have been reported to persist in ...
