About

The qPCR test detects the genome (DNA) of Equine Herpesvirus Type 2 (EHV-2).

Serological testing has limited value for detecting reactivation of EHV-2 because the virus can remain latent while still being shed at levels capable of infecting other horses.

Molecular detection by qPCR is the most sensitive, specific and accurate method for assessing the infectivity of affected horses.

What is Equine Herpesvirus Type 2 (EHV-2)?

Equine Herpesvirus Type 2 (EHV-2) belongs to the Gammaherpesvirinae subfamily and is widespread in horse populations.

It has been isolated from both healthy horses and animals showing clinical disease.

EHV-2 establishes persistent infections and is considered a potential predisposing factor for Rhodococcus equi respiratory infections. It has also been suggested that EHV-2 may contribute to the reactivation of latent EHV-1 and EHV-4 infections.

Why test?

The qPCR test provides rapid and accurate detection of Equine Herpesvirus Type 2 (EHV-2) and is the preferred method for identifying active viral shedding and assessing infectivity.

Clinical signs

EHV-2 infection occurs most commonly in young foals.

Clinical signs may include:

Keratoconjunctivitis
Respiratory disease
Pneumonia
Pharyngitis
Fever
Enlarged lymph nodes
Inappetence or anorexia
General malaise
Poor performance

There is no evidence that EHV-2 causes abortion.

Transmission

Most foals become infected at an early age.
Transmission is believed to occur through aerosolised respiratory secretions from infected horses.
Initial viral replication occurs in the upper respiratory tract.
Prenatal infection has not been documented.
The virus has not been detected in colostrum or milk.
Experimental studies have shown that infected foals may develop mild rhinitis, conjunctivitis and nasal viral shedding after in utero exposure.

Prevention

Evidence suggests that controlling EHV-2 infection may help reduce the risk of Rhodococcus equi pneumonia in foals.

Preventive and therapeutic approaches reported include:

Passive immunisation with hyperimmune equine serum.
Active immunisation using vaccines containing EHV-2 glycoprotein antigens.
Ophthalmic treatment of ocular disease with idoxuridine or trifluridine, combined with antibiotics and non-steroidal anti-inflammatory drugs where appropriate.

FAQs

Who collects the sample? Your veterinarian. See Sample for the material and the volume this test requires.

How should the sample be sent? Keep it cool and send it by tracked courier as soon as it is collected. Shipping is arranged and paid for by the client.

What happens if the sample arrives unsuitable? We contact you before processing and ask for a new sample.

Can other tests be added to the same sample? Often yes, if the material and the volume allow it. Ask us before shipping.

How long does it take? See Turnaround. The count starts when the sample arrives at the laboratory, not when you order.

More

Unlike serological testing, qPCR allows detection of active viral shedding and is considered the preferred method for assessing infectivity in horses with suspected EHV-2 infection.
