The pig from an animal shelter in the Canton of Neuchâtel had been sent to the Clinic for Swine, Vetsuisse Faculty, University of Bern, on Saturday, 2nd May because of the following symptoms: three weeks of lameness, swollen carpal joints, increased body temperature, inappetence and vomiting. At the clinic the pig developed fever, respiratory symptoms and petechiae on ears and trunk.
On Monday, 4th May blood samples were taken, the animal was euthanised and sent to pathology. It had been kept in the isolation unit of the clinic during the whole period of hospitalization. Blood samples were directly sent to the national reference laboratory "Institute of Virology and Immunology (IVI)" and tests yielded negative results for African swine fever and classical swine fever. However, the samples tested positive for antibodies against porcine reproductive and respiratory syndrome virus (PRRSV) as well as for viral RNA of the genotype 1 (EU genotype).
The animal shelter where the positive pig came from is keeping another about six months old pig, that tested positive for antibodies against PRRSV today. These two pigs arrived together at the shelter. The movement history of these two pigs needs to be clarified. Two Vietnamese pot-bellied pigs, already kept in the shelter before the arrival of the piglets, tested negative for antibodies and viral RNA. Movement of these animals has been prohibited. Within the coming days, holdings keeping pigs in a range of 5 km around the animal shelter will be tested as well.
