Readiness Level of Spanish Labs to Detect Mpox Clade Ib: A Nationwide EQA

open access: yesJournal of Medical Virology, Volume 98, Issue 5, May 2026.
ABSTRACT To assess the preparedness and diagnostic capacity of Spanish clinical microbiology laboratories to detect the emerging monkeypox virus (MPXV) Clade Ib through a nationwide external quality assessment. A blinded 16‐sample panel (serum and DNA eluates) containing MPXV Clade Ib, Clade II, vaccinia, and negatives was distributed.

THE STABILITY OF VARIOLA VIRUS PROPAGATED IN EMBRYONATED EGGS [PDF]

open access: yesJournal of Experimental Medicine, 1943
After 24 transfers in embryonated eggs a strain of variola virus (Chinese) was established in the testis of the rabbit and maintained for 11 passages at intervals of 7 days. Residence in the rabbit testis was not accompanied by any significant alteration in the species identity of the virus.

Expression and functional characterisation of Variola and Monkeypox virus tumour necrosis factor receptor (TNFR) proteins [PDF]

open access: yes, 2012
University of Technology, Sydney. Faculty of Science.Tumour necrosis factor-a (TNFα) is a pleiotropic cytokine that plays a critical role in cellular response to virus infection. Virtually all poxviruses encode genes that are homologous to human tumour

Thermo-Efficient Strains of Variola Major Virus

open access: yesJournal 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.

Evidence for Persistence of Ectromelia Virus in Inbred Mice, Recrudescence Following Immunosuppression and Transmission to Naïve Mice.

open access: yesPLoS 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 ...

Orthopoxvirus Genome Evolution: The Role of Gene Loss

open access: yesViruses, 2010
Poxviruses are highly successful pathogens, known to infect a variety of hosts. The family Poxviridae includes Variola virus, the causative agent of smallpox, which has been eradicated as a public health threat but could potentially reemerge as a ...

Orthopoxvirus Genes That Mediate Disease Virulence and Host Tropism

open access: yesAdvances in Virology, 2012
In the course of evolution, viruses have developed various molecular mechanisms to evade the defense reactions of the host organism. When understanding the mechanisms used by viruses to overcome manifold defense systems of the animal organism ...
