Abstract:
In this case report the potential relationship between an Entero- or Teschovirus infection and paresis in two sows in an Austrian breeding farm is discussed. According to the anamnesis and the results of clinical examination at the University of Veterinary Medicine potential diagnoses were discussed. The paralysis of the back legs could either be due to non infectious traumata, selen poising and organphosphate or to infectious diseases like erysipelas, encephalomyelitis due to Teschovirus, pseudorabies, swine fever and brucellosis. During necropsy space-occupying lesions in the spinal cord were excluded, because abscesses can cause paralysis due to nerve compression. These differential diagnoses were excluded during pathological examination. The presence of a severe non-purulent encephalomyelitis was assumed to be indicative for an Entero- or Teschovirus infection. The clinical and histological findings were mainly in accordance with descriptions in literature. However, the results of the molecular-genetic examination in the AGES did not indicate an infection with the notifiable porcine teschovirus 1. Porcine enterovirus 1 was found in the spinal cord sample of one of the animals. Due to often silent disease, infection is often clinically inapparent and is therefore difficult to diagnose. Evidence for infection is a positive finding in porcine teschovirus 1 specific sequencing.
