Summary
Equine coronavirus can cause illness in horses. While horses may be susceptible to SARS-CoV-2, they appear to be incidental hosts, necessitating monitoring for human-to-equid transmission of COVID-19.
Area of Science:
- Veterinary Virology
- Equine Infectious Diseases
- Zoonotic Disease Surveillance
Background:
- Coronaviruses are RNA viruses impacting mammals and birds.
- Equine coronavirus causes gastrointestinal issues and systemic signs in horses.
- Horses exhibit susceptibility to SARS-CoV-2 due to ACE-2 receptor homology.
Purpose of the Study:
- To review the potential for SARS-CoV-2 transmission to equids.
- To highlight the importance of monitoring horses for COVID-19.
- To inform veterinary professionals about equine coronavirus and SARS-CoV-2.
Main Methods:
- Literature review on coronaviruses in equids.
- Analysis of ACE-2 receptor homology between humans and horses.
- Discussion of potential spillover events and surveillance needs.
Main Results:
- Equine coronavirus is an established pathogen in horses.
- Horses are likely incidental hosts for SARS-CoV-2.
- Occasional human-to-horse SARS-CoV-2 spillover is possible.
Conclusions:
- Continued monitoring of equids for SARS-CoV-2 is crucial.
- Further clinical and seroepidemiological data are needed.
- Veterinary vigilance is essential for managing potential zoonotic transmissions.

00:57Viral Recombination
23.7K
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

01:29Viruses with RNA Genomes
74
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...

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...

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’...

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...

5.3K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
