Equine arteritis virus.
Summary
This research centers around the recent progress in understanding Equine arteritis virus (EAV), the causative agent of equine viral arteritis (EVA) in horses; it covers the viral architecture, replication, evolution, epidemiology and genetic variation, as well as looking into possible vaccination and treatment strategies.
Understanding the Equine Arteritis Virus (EAV)
EAV is a virus that causes equine viral arteritis, a respiratory and reproductive disease in equids – members of the horse family such as horses, donkeys, and zebras. This review aims to encapsulate the recent understanding related to the virus and its infection in horses. The study references the application of contemporary genomic techniques and infectious cDNA clones of various EAV strains to obtain extensive information about the basic molecular biology of the virus. Some topics explored include:
- The architecture of the EAV virion, which refers to the structure and make-up of the virus particle itself.
- The replication process of the virus, detailing how the EAV copies itself within host cells.
- The evolution of EAV, providing insight into how the virus has changed and adapted over time.
- The virus’s molecular epidemiology and genetic variation, exploring the distribution and determinants of EAV within horse populations.
Pathogenesis and Host Immune Response
The review also explored how the EAV infection develops and progresses in horses: the pathogenesis. This includes understanding how host genetics might influence the susceptibility to the disease. On the other hand, the host immune response investigates how the immune system of the horse reacts to the EAV infection.
- Pathogenesis: The study delves into how the disease progresses after the horse’s initial infection. It highlights the importance of understanding the influence of the host’s (horse) own genetics on susceptibility to the disease. This information is invaluable as it can help identify horses that are more prone to the infection and take precautionary measures accordingly.
- Host Immune Response: This refers to how the horse’s immune system responds to the infection caused by EAV. Gaining insight into this can provide critical information on the body’s natural defense against the virus and can be instrumental in establishing effective treatments.
Vaccination and Treatment Strategies
In addition to understanding the structure and behavior of the EAV, the review considers current potential vaccination and treatment strategies. Armed with the insights gained from the earlier parts of the review, discussions on promising preventive and therapeutic measures are held. These include the exploration of designing vaccines as a preventive approach and identifying treatments to manage or cure horses already infected by EAV.
