Summary
Horses are not a dead-end host for equine influenza A virus, as recent canine transmissions show. Equine influenza viruses evolve and pose ongoing risks.
Area of Science:
- Veterinary Virology
- Equine Infectious Diseases
- Influenza Virus Evolution
Background:
- Traditionally, horses were considered a "dead-end" host for influenza A viruses.
- Equine influenza viruses were thought to be genetically stable.
- Recent equine lineage influenza virus transmission to dogs challenges this view.
Purpose of the Study:
- To review recent advancements in equine influenza virus epidemiology and evolution.
- To summarize clinical presentation, diagnostics, and vaccination strategies for equine influenza.
Main Methods:
- Review of current scientific literature on equine influenza.
- Analysis of epidemiological data and evolutionary trends.
- Summary of diagnostic and clinical findings.
Main Results:
- Equine influenza viruses are not genetically static and exhibit evolutionary dynamics.
- Transmission of equine-lineage influenza viruses to other species, like dogs, has been documented.
- Equine influenza remains a significant concern in horse populations.
Conclusions:
- The role of the horse as a "dead-end" host for influenza A is being re-evaluated.
- Understanding the evolution and epidemiology of equine influenza is crucial for disease control.
- Effective diagnostic and vaccination strategies are essential for managing equine influenza.

Influenza
70
Influenza is an acute, highly communicable viral disease that affects the respiratory tract and is responsible for seasonal epidemics worldwide. Influenza A is the most prevalent type associated with widespread outbreaks and is subtyped based on two surface glycoproteins: hemagglutinin (H) and neuraminidase (N), as in H1N1. These glycoproteins are essential for viral infectivity, transmission, and immune recognition. Transmission occurs primarily through respiratory droplets and contaminated...

Viral Recombination
22.1K
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.

Leaky Scanning
4.5K
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...

Arboviral Encephalitis
52
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
