Abstract

Porcine epidemic diarrhoea virus (PEDV) can cause a severe enteric disease affecting pigs of all ages. In January 2016, diarrhoea with occasional vomiting was observed in a small pig farm in Hungary. All animals became affected, while mortality (of up to 30%) was only seen in piglets. Samples from different age groups and the carcass of a piglet were examined by various methods including pathology, bacteriology and molecular biology. PEDV was confirmed by PCR and its whole genome sequence was determined. The sequence PEDV HUN/5031/2016 showed high identity with recently reported European viruses. Differences were found mostly in the S gene, where recombination was detected with a newly identified and already recombinant swine enteric coronavirus (Se-CoV) from Italy. The present report describes the first porcine epidemic diarrhoea outbreak in Hungary after many years and gives an insight into the genetics of the Hungarian PEDV.
