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 ...

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 ...

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 ...

Orthopoxvirus Purification for High Containment Laboratories
Purification of large viruses in a high containment laboratory can create unique challenges. Traditional purification methods for large viruses rely on equipment and techniques that are not ideal for high containment work. Poxvirus purification has long relied on the use of Genetron®, a reagent that is no longer available.Laura, Hughes +4 more

Mouse Models for Studying Orthopoxvirus Respiratory Infections
2004Concern regarding the use of variola and monkeypox viruses as bioterrorist agents has led to an increased study of orthopoxviruses to understand the molecular and cellular basis of pathogenesis and develop safe and effective antivirals and vaccines against smallpox.

Inactivation of orthopoxvirus for diagnostic PCR analysis
Journal of Virological Methods, 2007Diagnoses of ongoing viral infections commonly rely on PCR methodology. Sample material that may contain hazardous virus should be efficiently inactivated in biological containment or bed-side before diagnostic PCR analysis. Surprisingly little documentation is available for inactivation of human viral pathogens by inactivation reagents that allow for ...

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

Two types of deletions in orthopoxvirus genomes
Virus Genes, 1995The genome nucleotide sequences of two strains of variola major virus and one strain of vaccinia virus were compared. One hundred and sixty-eight short (less than 100 bp in length) and eight long (more than 900 bp in length) deletions, four deletion/insertion regions, and four regions of multiple mutational differences between variola and vaccinia ...

Genus Orthopoxvirus: Variola virus
2007Variola major virus caused the human disease smallpox; interpretations of the historic record indicate that the initial introduction of disease in a naive population had profound effects on its demographics. Smallpox was declared eradicated by the World Health Organization (WHO) in 1980.

Orthopoxvirus Genome Sequencing, Assembly, and Analysis
Poxviruses have exceptionally large genomes compared to most other viruses, which represent unique challenges to sequencing and assembly due to complex features such as repeat elements and low complexity sequences. The 2022 global mpox outbreak led to an unprecedented level of poxvirus sequencing as public health and research institutions faced with ...Crystal M, Gigante +2 more
