Summary
Arteriviruses are enveloped RNA viruses infecting mammals. This summary details the International Committee on Taxonomy of Viruses report on the Arteriviridae family, covering their characteristics and impact.
Area of Science:
- Virology
- Microbiology
- Animal Health
Background:
- The family Arteriviridae includes enveloped RNA viruses.
- These viruses infect non-human mammals independently of vectors.
- Infections can be persistent, ranging from asymptomatic to severe disease.
Purpose of the Study:
- To summarize the International Committee on Taxonomy of Viruses (ICTV) report on the Arteriviridae family.
- To provide an overview of arterivirus characteristics and classification.
- To highlight the veterinary and zoonotic significance of certain arteriviruses.
Main Methods:
- Review and synthesis of the ICTV report on Arteriviridae.
- Analysis of viral genome structure, virion morphology, and protein composition.
- Compilation of information on host range and disease manifestations.
Main Results:
- Arteriviruses possess linear, positive-sense RNA genomes (12.7–15.7 kb).
- Virions are spherical to pleomorphic (50–74 nm) with 8–11 viral proteins.
- The family includes important veterinary pathogens and viruses infecting rodents and non-human primates.
Conclusions:
- Arteriviruses represent a significant viral family with diverse impacts on mammalian health.
- Understanding arterivirus taxonomy is crucial for disease management and research.
- The ICTV report provides a comprehensive resource for the Arteriviridae family.

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...

264
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...

47.8K
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...

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’...

01:28Introduction to Virus
506
Viruses are unique biological entities that blur the boundary between living and non-living systems. Although they lack cellular structure and metabolic processes, they can exhibit characteristics of life when infecting a host. Their defining feature is a nucleic acid core, composed of either DNA or RNA, encapsulated within a protein coat called a capsid. This simple structure allows them to invade host cells and use their machinery for replication efficiently.Viral Structure and...
