EM: erythema multiforme INTRODUCTION Orf, also known as ecthyma contagiosum, contagious pustular dermatitis, infectious pustular dermatosis, ovine pustular dermatitis, and sore mouth, is a viral zoonotic disease resulting from the direct or indirect contact of damaged skin with infected animals. The virus is endemic in sheep and goats worldwide and manifests as an acute contagious skin conditio...

Coupled translation, first described in the M2 gene of pneumovirus respiratory syncytial virus (RSV), is an alternative mechanism of translational initiation in which the ribosomes which translate the first (M2-1) open reading frame (ORF) move a short distance upstream after termination and reinitiate translation from a second (M2-2) overlapping ORF. Here, we show that the same mechanism occurs...

Orf virus infection has been prevalent continuously in the population of wild Japanese serows (Capricornis crispus), goat-like grazing cloven-hoofed mammal species that live mainly in mountainous areas of Japan. Currently, definitive diagnosis of infection requires time-consuming laboratory work. To diagnose rapidly on-site, we developed a field-friendly procedure for the detection of orf virus...

Genomic segment S12 of rice dwarf virus and segment S9 of wound tumor virus, both members of the genus Phytoreovirus, have small out-of-phase overlapping open reading frames (ORFs). Western blot (immunoblot) analysis revealed that rice dwarf virus S12 mRNA specified translation products from the large ORF and two overlapping small ORFs both in rice plant hosts and in Spodoptera frugiperda insec...

We prove a Central Limit Theorem for the sequence of random compositions of a two-color randomly reinforced urn. As a consequence, we are able to show that the distribution of the urn limit composition has no point masses.

Vaccinia virus encodes several proteins, the activity of which is essential for multiplication in different cell types. Both the C7L and K1L open reading frames (ORFs) have been characterized as viral determinants for multiplication in human cells. To confirm and extend these findings we inserted the C7L ORF into the genome of a mutant virus unable to multiply in human cells and showed that thi...

Many satellite RNAs (sat-RNAs) can attenuate or intensify the symptoms produced by their helper virus. Sat-RNA C, associated with turnip crinkle virus (TCV), was previously found to intensify the symptoms of TCV on all plants in which TCV produced visible symptoms. However, when the coat protein open reading frame (ORF) of TCV was precisely exchanged with that of cardamine chlorotic fleck virus...

Infection by the parapoxvirus orf virus causes proliferative skin lesions in which extensive capillary proliferation and dilation are prominent histological features. This infective phenotype may be linked to a unique virus-encoded factor, a distinctive new member of the vascular endothelial growth factor (VEGF) family of molecules. We constructed a recombinant orf virus in which the VEGF-like ...

Soybean chlorotic mottle virus (SbCMV) is the type species of the genus 'Soybean chlorotic mottle-like viruses', within the family Caulimoviridae. The double-stranded DNA genome of SbCMV (8178 bp) contains eight major open reading frames (ORFs). Viral genes essential and non-essential for the replication and movement of SbCMV were investigated by mutational analysis of an infectious 1.3-mer DNA...
