The poxvirus preparation CONPIND initiated the production of the two major inflammatory mediators interleukin-1 alpha (IL-1 alpha) and tumour necrosis factor-alpha (TNF-alpha) in whole blood and in blood mononuclear cell cultures of man at 37 degrees C within 12-48 h. The release of the cytokines followed a dose-efficacy curve. High levels of IL1-alpha (up to 810 pg/ml) and TNF-alpha (up to 533 pg/ml) were determined by sandwich enzyme-linked immunosorbent assay.

Background: The orf virus (ORFV) is a viral pathogen that primarily causes contagious ecthyma in humans and different ruminants. The infection, which is common worldwide, causes large-scale economic losses to animal breeders.
Objective And Methods: In this study, tissue samples collected from eight randomly selected goats with dermatological lesions on the teats were examined in different goat herds.

Vaccinia virus (VACV), the prototype member of the Poxviridae family, has played a crucial role in medicine as a key component in the development of smallpox vaccines, contributing to the eradication of this deadly disease. Beyond its historical significance, VACV continues to be pivotal in researching metabolic alterations induced by viral infections. Studies have revealed that VACV can impact pathways such as glycolysis, the tricarboxylic acid (TCA) cycle, and lipid metabolism in host cells, offering valuable insights into host-virus interactions and broader cellular metabolism.

Poxviruses are double-stranded DNA viruses that represent the largest known highly pathogenic viruses infecting humans. They undergo dramatic morphological changes during their maturation process, resulting in structural differences between each virion, and their surface is decorated with more than a dozen randomly distributed surface proteins that facilitate viral entry. These are the main reasons poxviruses have eluded high-resolution structure determination.

Bioluminescent images of viral replication in live animals (in vivo) reveal disease dynamics and effects of medical countermeasures over time. After selecting an appropriate orthopoxvirus animal model for the study, a recombinant virus with the firefly luciferase gene inserted in the genome is used to infect the animals. On the day of bioluminescent imaging, the substrate, D-luciferin, is prepared; animals are sedated and injected with the substrate and IVIS imager is utilized; various bioluminescent images are acquired; then animals recover and are able to continue in the study.

The low-frequency natural recombination that is detected in poxvirus-infected cells has long been used to genetically modify poxviruses. Such recombinant poxviruses have found many applications as vaccines for preventing infectious diseases and as experimental cancer therapeutics. Unfortunately, these methods are time consuming, can leave behind "scars" or selectable markers, and many months of work may be required to generate plaque-purified recombinants bearing multiple virus gene substitutions, deletions, and/or inserted transgenes.
