We investigated the first laboratory-confirmed human case of cowpox virus infection in Russia since 1991. Phylogenetic studies of haemagglutinin, TNF-α receptor-like protein and thymidine kinase regions showed significant differences with known orthopoxviruses, including unique amino-acid substitutions and deletions. The described cowpox virus strain, taking into account differences, is genetically closely related to strains isolated years ago in the same geographical region (European part of Russia and Finland), which suggests circulation of viral strains with common origin in wild rodents without spread over long distances and appearance in other parts of the world.

Monkeypox virus (MPXV) is an enclosed, double-stranded DNA virus from the Orthopoxvirus genus, which also contains variola, vaccinia, and cowpox. MPXV, which was once confined to West and Central Africa, has recently had a rebound, spreading beyond its original range since 2017. The virus is distinguished by its unique morphology, which includes an oval or brick-shaped structure and a complex lipid and protein makeup.

Previously obtained highly immunogenic Env-VLPs ensure overcoming the natural resistance of HIV-1 surface proteins associated with their low level of incorporation and inaccessibility of conserved epitopes to induce neutralizing antibodies. We also adopted this technology to modify Env trimers of the ZM53(T/F) strain to produce Env-VLPs by recombinant vaccinia viruses (rVVs). For VLP production, rVVs expressing Env, Gag-Pol (HIV-1/SIV), and the cowpox virus hr gene, which overcomes the restriction of vaccinia virus replication in CHO cells, were used.

Introduction: Shelters for stray dogs and cats deserve careful monitoring for zoonotic risk, as they represent a crucial point for prevention and control of infection spread. Data sorting to prioritize zoonotic agents in a geographic area need constant updating, but no regular official programs are ongoing, to allow an efficient risk survey for these animal species. This study aimed to conduct a comprehensive investigation of the prevalence of certain known, potential and emerging zoonoses within the framework of the routine monitoring of dog and cat shelters in North-East Italy.

Article Synopsis
- Poxviruses, especially those in the orthopoxvirus genus, have caused significant health issues throughout history, with smallpox being a prominent example.
- Smallpox, caused by the Variola virus, was successfully eradicated in 1980, marking a milestone in public health and requiring extensive research on orthopoxviruses.
- The text explores both historical and current epidemiology of poxvirus infections, focusing on significant viruses like Monkeypox and Vaccinia.

Article Synopsis
- Monkeypox virus (MPXV) caused a significant outbreak in 2022, with over 90,000 cases and 181 fatalities, exhibiting signs of evolution and adaptation to hosts.
- Research revealed that different MPXV isolates from the Franconia region have mutations affecting their replication capabilities, particularly a variant with a mutation (D616L) that shows faster viral replication.
- The study also found that dihydroorotate dehydrogenase (DHODH) inhibitors are effective against MPXV and related viruses, offering promising low-toxicity options for future antiviral drug development.
