Summary
The Spinareoviridae virus family includes icosahedral, non-enveloped viruses with segmented dsRNA genomes. These viruses infect diverse hosts, including humans, animals, plants, and fungi, with some posing significant pathogenic risks.
Area of Science:
- Virology
- Microbiology
- Pathogen Discovery
Background:
- The Spinareoviridae family comprises icosahedral, non-enveloped viruses.
- These viruses possess segmented double-stranded RNA (dsRNA) genomes, typically with 9-12 linear segments totaling 23-29 kbp.
- Spinareovirids exhibit a wide host range, infecting animals, fungi, and plants.
Purpose of the Study:
- To provide a summary of the International Committee on Taxonomy of Viruses (ICTV) report on the Spinareoviridae family.
- To consolidate information on the taxonomy, characteristics, and host range of Spinareoviridae.
- To highlight the pathogenic potential of certain Spinareoviridae members.
Main Methods:
- Review and summarization of the official ICTV report on the Spinareoviridae family.
- Compilation of data on viral structure, genome composition, and host interactions.
- Identification of key examples of pathogenic Spinareoviridae.
Main Results:
- The Spinareoviridae family is characterized by icosahedral, non-enveloped virions and segmented dsRNA genomes.
- Infection spans across animals, fungi, and plants, demonstrating a broad host tropism.
- Notable pathogenic members include Colorado tick fever virus (humans), avian orthoreoviruses (livestock), aquareoviruses (fish), and rice viruses (plants).
Conclusions:
- The Spinareoviridae family represents a significant group of viruses with diverse hosts and pathogenic capabilities.
- Understanding Spinareoviridae is crucial for managing diseases in humans, livestock, and agriculture.
- This summary serves as a reference for the current classification and knowledge of the Spinareoviridae family.

01:29Viruses with RNA Genomes
86
RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

01:29Subviral Agents
77
Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...

Archaeal viruses play a crucial role in the ecosystems of extremophilic archaea, particularly those belonging to the phyla Euryarchaeota and Crenarchaeota. By shaping host evolution and facilitating gene transfer, these viruses influence microbial communities and contribute to genetic diversity in extreme environments. The archaea they infect thrive in acidic hot springs and hydrothermal vents characterized by high temperatures and low pH. Archaeal viruses exhibit remarkable structural...

01:10Retrovirus Life Cycles
46.5K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

01:26Size and Structure of Viral Genomes
103
Viral genomes exhibit remarkable diversity in size, structure, and composition, influencing their replication strategies and interactions with host cells. These genomes consist of either DNA or RNA and may be linear or circular. Additionally, they can be single-stranded or double-stranded, with each configuration affecting how the virus propagates within a host. RNA viruses, for instance, generally have smaller genomes than DNA viruses, a factor that contributes to their high mutation rates and...

02:33Retroviruses
12.6K
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...
