Equine arteritis virus (EAV) is a single stranded positive sense RNA genome classified in the genus, Arterivirus, family Arteriviridae. Equine viral arteritis (EVA) is a reportable, highly contagious disease associated with sporadic outbreaks of acute respiratory disease and abortion in horses. Infection can spread between horses at mating, by artificial insemination with contaminated semen, by contact with aborted foetuses, or by direct contact with droplets from the respiratory tract, i.e. through coughing and snorting.
EAV primarily infects macrophages and vessel endothelium throughout a horse's body. The initial infection is followed by viral dissemination via the bloodstream, resulting in viremia. Clinical signs first appear two to 13 (average seven) days after infection, and a fever may continue for two to nine days. Acutely infected horses shed the virus in nasal secretions for up to 16 days. EVA is a notifiable disease of horses. The diseases' greatest economic impact is on the horse-breeding industry.
Swabs / secretion and tissue should be transported at 4°C. Semen samples must be frozen after collection and delivered within 24 hours.
It is required to add RNA preservative media to swabs / secretion and tissue only. Contact MBG Lab for specimen tubes containing RNA preservative if required.
Turn Around Time (TAT)
Normal Turnaround time for pathogen Identification is within 5 working days. Urgent Samples will be reported within half of the minimum test period & will be Charged Double.
Samples delivered after 11:00 AM will be processed next working day unless urgent.
