Re-emergence of a genetic outlier strain of equine arteritis virus: Impact on phylogeny.

Abstract: Equine arteritis virus (EAV) is the causative agent of equine viral arteritis (EVA), a respiratory and reproductive disease of equids, which is notifiable in some countries including the Great Britain (GB) and to the OIE. Herein, we present the case of a persistently infected stallion and the phylogenetic tracing of the virus strain isolated. Discussing EAV occurrence and phylogenetic analysis we review features, which may aid to harmonise and enhance the classification of EAV.

The research article deals with the resurgence of a unique strain of Equine Arteritis Virus (EAV), exploring its impact on phylogeny and the implications for equine viral arteritis (EVA), a significant equine respiratory and reproductive illness.

Objective of the Research

  • The main objective of the study was to investigate the re-emergence of a distinct EAV strain in a persistently infected stallion, including tracing this strain’s phylogenetic lineage.

Equine Arteritis Virus (EAV)

  • EAV is a virus causing equine viral arteritis (EVA), a respiratory and reproductive disease affecting equids, a family that includes horses and related animals.
  • The disease is noteworthy enough that it must be reported in certain regions, such as Great Britain, and to international organizations like the OIE (World Organization for Animal Health).

Study Focus

  • The research primarily centered around a stallion that was persistently infected with a unique strain of EAV. The horse was seen as a case study to investigate the re-emergence of this viral strain.
  • The study also involved exploring the phylogenetic lineage of the specific EAV strain found in the stallion – i.e., tracing back its evolutionary background and changes over time.

Implications for EAV Classification

  • By studying the characteristics of the unique EAV strain and its phylogenetic correspondence, the researchers hoped to review features which could aid in harmonizing and improving the classification of EAV.
  • Better classification can lead to improved recognition and handling of infections, helping to reduce the spread of the disease and mitigate its impacts.
