Reovirus is a double-stranded RNA-containing virus that possesses the distinctive ability to replicate in transformed cells while sparing normal cells, both in vitro and in vivo, reovirus, in rodent models of cancer. Reovirus discovery of this property only arose through years of basic research on the biology of reovirus infection, reovirus.

Mammalian orthoreovirus MRV , also known as reovirus, was discovered in the s and became the first reported segmented double-stranded RNA virus.

Reovirus

Sedoreoviridae formerly Reoviridae is a family of double-stranded RNA viruses. Member viruses have a wide host range, including vertebrates , invertebrates , plants, protists and fungi. Even though viruses in the family Reoviridae have more recently been identified with various diseases, the original name is still used. Reovirus infections occur often in humans, but most cases are mild or subclinical. Rotaviruses , however, can cause severe diarrhea and intestinal distress in children, and lab studies in mice have implicated orthoreoviruses in the expression of coeliac disease in pre-disposed individuals. Despite the ease of finding reoviruses in clinical specimens, their role in human disease or treatment is still uncertain. Some viruses of this family, such as phytoreoviruses and oryzaviruses , infect plants. Most of the plant-infecting reoviruses are transmitted between plants by insect vectors. The viruses replicate in both the plant and the insect, generally causing disease in the plant, but little or no harm to the infected insect. The core contains the genome segments, each of them encode a variety enzyme structure which is required for transcription. Reoviruses have a unique structure which is contains a glycolisated spike protein on the surface. The genomes of viruses in family Reoviridae contain 9—12 segments which are grouped into three categories corresponding to their size: L large , M medium and S small. Segments range from about 0.

Wild birds have great prominence in the transmission of diseases to humans, mainly due to their ease of access to human populations, raising concerns about the potential impact of that proximity on public health. We obtained fecal specimens from 47 species of wild birds for RNA extraction, ARV and PBV detection utilizing molecular methods, nucleotide sequencing, and phylogenetic analysis. ARV prevalence was 0. The PBV strains were assigned to genogroup I based on phylogenetic analysis, and they shared a strong phylogenetic link with strains isolated from different geographic locations. The ARV strain was more closely related to strains that had previously circulated in the same region. The presence of ARV and PBV in this habitat suggests that infection cycles of these agents occur naturally in the wild ecosystem, potentially triggering transmission events between bird species and humans. Additional studies are required to determine the epidemiology, origin, evolution, and emergence of new potentially pathogenic viruses in the Amazon.

Reovirus

Federal government websites often end in. The site is secure. Most viruses that replicate in the cytoplasm of host cells form neoorganelles that serve as sites of viral genome replication and particle assembly. These highly specialized structures concentrate viral proteins and nucleic acids, prevent the activation of cell-intrinsic defenses, and coordinate the release of progeny particles. Reoviruses are common pathogens of mammals that have been linked to celiac disease and show promise for oncolytic applications.
