Orf disease is a viral infection, affecting patients being involved in the care of livestock either professionally or habitually. It is also known as ecthyma contagious, contagious pustular dermatitis or infectious euphoria being a rare zoonotic disease caused by an epitheliotropic DNA virus from the parapoxvirus group. We report a case of Orf disease affecting the hand of a patient with rheumatoid arthritis (RA) on treatment with methotrexate and adalimumab, an anti-tumor necrosis factor biological agent. The patient was successfully treated with doxycycline, while immunosuppressive treatment was discontinued.

Maternal vaccination is essential for safeguarding both mother and foetus from infectious diseases. This study investigated the immunogenicity and efficacy of a maternal ORF-B2L genetic vaccine in a pregnant rat model, focusing on maternal-neonatal immune modulation, placental and neonatal spleen transcriptomics and the underlying mechanisms contributing to neonatal immune development. Female rats received intramuscular injections of either a gene vaccine (GV) containing 200 μg of recombinant ORF-B2L DNA and 50 μg of a subunit protein or an empty plasmid as a control.

Genome-wide translational profiling has uncovered the synthesis in human cells of thousands of microproteins, a class of proteins traditionally overlooked in functional studies. Although an increasing number of these microproteins have been found to play critical roles in cellular processes, the functional relevance of the majority remains poorly understood. Studying these low-abundance, often unstable proteins is further complicated by the challenge of disentangling their functions from the noncoding roles of the associated DNA, RNA, and the act of translation.

Objectives: To investigate the pathogenicity of feline herpesvirus-1 (FHV-1) to the cornea, FHV-1 strains isolated from feline eyes with dendritic ulcers were subjected to genomic analysis to determine whether FHV-1 vaccine strains are involved in the formation of dendritic ulcers.
Methods: All open reading frame (ORF) sequences of the three F2 strains (Virbac, Intervet and Merial) and the FHV-1 clinical isolates from cats registered in GenBank were compared to detect nucleotide variants unique to the F2 strains, with those nucleotides then being used for simple genotyping of the F2 strains. In all isolates from feline eyes with dendritic ulcers, the regions including nucleotide variants of the F2 strain were amplified with PCR and sequenced.

Carbapenems are last-resort antibiotics for treating bacterial infections. The widespread acquisition of metallo-β-lactamases, such as VIM-2, contributes to the emergence of carbapenem-resistant pathogens, and currently, no metallo-β-lactamase inhibitors are available in the clinic. Here we show that bacteria expressing VIM-2 have impaired growth in zinc-deprived environments, including human serum and murine infection models.

The NS1 protein of nine mosquito-borne flaviviruses, including Dengue virus 1-4, Japanese encephalitis virus, West Nile virus, Yellow fever virus, Tembusu virus, and Zika virus, shows distinct codon usage and evolutionary traits. Codon usage analysis shows notable base composition bias and non-conservatism in NS1, with distinct evolutionary traits from its ORF. Analysis of relative synonymous codon usage (RSCU) indicates that the NS1 genes exhibit non-conservative RSCU patterns within different mosquito-borne pathogenic flaviviruses.
