1 ) Herpes virus EHV1 / EHV4 (Horse) PCR

The Disease |
Infections with EHV1 and EHV4 primarily cause diseases of the respiratory tract. The relevance of clinical symptoms is depending on age and immune status of the infected animal. Especially infections with EHV1 can spread beyond the respiratory mucosa and cause severe manifestations of the disease: abortions, perinatal death of foals, neurologic disease. Once infected, horses stay carrier of virus lifelong. The virus can be activated endogenously by adverse conditions (stress etc.). Latent organs are the lymphatic tissues and the leucocyte fraction. Including vaccinated horses there is a high sero-prevalence within population. In recent years there are an increasing number of reports about an extremely severe EHV-1 associated form of neurologic disease, which is caused by an neurotropic EHV-1 strain with aggressive replication.

Description |
PCR
PCR from nasal swabs/secretions of respiratory tract, liquor cerebrospinalis or abortion material including faecal membranes. Blood is only second-choice material during pyremia. Since the leucocyte fraction is a latent organ an analysis of the buffy coat can be tempted. Positive results mean that the horse was in contact with Herpes virus. Interpretation as for acute or chronic infection is vague. In contrast analysis of blood can make sense in young animals.

Description |
Realtime PCR
Influenza A viruses belong to the family Orthomyxoviridae and are mostly found in humans, pig, poultry and horses, but also in many others such as birds or dogs.
Horse
Equine influenza is caused by the subtypes A equi 1 (H7N7) and A equi 2 (H3N8), although
H7N7 has not been very present anymore over the past 30 years. In susceptible
Equidae, an infection causes fever and a rough, dry cough. In unvaccinated populations,
the virus spreads quickly. Secondary bacterial infections with mucopurulent nasal
discharge are frequent and mask the clinical picture, especially in partially immune
populations.
Pig
Pigs may not only become infected with porcine, but also with human and avian influenza
viruses and thus contribute to the creation of reassortant influenza viruses. The influenza
pandemics in humans in 1918/19 and in 2009 were caused by pig influenza viruses. In
pigs, primary infections are usually linked to livestock transport. The infection spreads
explosively in the population.
