The preparation of orthopoxvirus DNA
Journal of Virological Methods, 1981Abstract A method is presented for the preparation of cross-linked, intact orthopoxvirus DNA from viral cores extracted from virus-infected cell cultures.

An Outbreak of Orthopoxvirus-Associated Disease in Horses in Southern Brazil
Journal of Veterinary Diagnostic Investigation, 2010 An outbreak of severe cutaneous disease associated with an orthopoxvirus in horses in southern Brazil is described. Fourteen Crioulo mares and foals from a husbandry farm developed papules, and vesicles progressing to proliferative and exudative lesions

A Retrospective Study of the Orthopoxvirus Molecular Evolution
Infection, Genetics and Evolution, 2012 The data on the structure of conserved genes of the Old and New World orthopoxviruses and unclassified Yoka poxvirus were used for a Bayesian dating of their independent evolution. This reconstruction estimates the time when an orthopoxvirus ancestor was transferred to the North American continent as approximately 50 thousand years ago (TYA) and allows

1990
Genetic analysis of orthopoxviruses has contributed substantially to our understanding of the functional organization of the poxvirus genome, and individual mutants provide invaluable tools for future studies of poxvirus biology. Deletion and transposition mutants, localized primarily in the termini of the genome, may be particularly useful for ...

Biologic and antigenic properties are often useful for identifying and differentiating orthopoxviruses (OPV). However, polymerase chain reaction (PCR) amplification, with either restriction cleavage or sequencing of amplicons, has been gaining credibility as a more rapid, specific, sensitive, and often cost-saving technique for research and diagnostic ...

Orthopoxvirus vaccines and vaccination
2007Immunization procedures against Variola virus, from the historical perspective most often first credited to Edward Jenner in the late 18th century, helped finally to eradicate smallpox from the world. Since its eradication, the study of this disease and its pathology has been given little attention; however, with the emergence of Monkeypox virus into ...

The mechanism of cytoplasmic orthopoxvirus DNA replication
Cell, 1981Orthopoxvirus DNA replication occurs in the cytoplasm of infected cells within discrete foci designated as virosomes. We show that newly synthesized rabbit poxvirus (RPV) virosomal DNA consists predominantly of concatamers wherein unit length molecules are joined by fusion of two left (LL) or right (RR) ends, resulting in genomes aligned in alternating

Biosecurity Implications for the Synthesis of Horsepox, an Orthopoxvirus
Health Security, 2017This article examines the biosecurity and biodefense implications resulting from the recent creation of horsepox virus, a noncirculating (extinct) species of orthopoxvirus. Here we examine the technical aspects of the horsepox virus synthesis and conclude that orthopox synthesis experiments currently remain technically challenging-and will continue to ...

Regulation of Orthopoxvirus Gene Expression
1990Poxviruses differ from the other major groups of DNA viruses with regard to their use of the cytoplasm, rather than the nucleus, as the site of transcription. Consistent with this strategy, poxviruses encode their own DNA-dependent RNA polymerase as well as many—if not all—of the additional enzymes and factors needed to synthesize functional capped ...

Pharmacological Review on Orthopoxvirus
Research Journal of Pharmacology and PharmacodynamicsMonkeypox is an emerging viral zoonotic disease caused by the monkeypox virus, which is particularly significant as it is endemic to Central and Western Africa. This disease is rare and manifests with a rash resembling that of smallpox. However, its transmission between individuals beyond close contact is limited, and the case fatality rates for ...
